Choosing a wet-type solenoid for a hydraulic directional valve requires attention to both electrical and mechanical compatibility. The control voltage is important, but it is only one part of the specification. Valve diameter, electromagnetic force, stroke, duty cycle, operating frequency, mounting dimensions, and working environment can all determine whether a solenoid will actuate the valve correctly.
The MFB(Z)1-YC Series Wet-Type Solenoids for Valves provides AC and DC configurations for conventional 6-diameter and 10-diameter hydraulic electromagnetic directional valves. The product family includes MFB1-YC AC wet-type solenoids and MFZ1-YC DC wet-type solenoids, allowing equipment manufacturers and hydraulic system integrators to select an actuator according to their existing control architecture.
MFB1-YC and MFZ1-YC: The Basic Difference
The most obvious distinction between the two series is their power supply.
The MFB1-YC series is designed for AC operation, with rated voltage options including AC110V and AC220V. It is intended for hydraulic equipment where the valve control circuit already uses AC power.
The MFZ1-YC series is designed for DC operation and supports rated voltage options including DC24V, DC110V, and DC220V. It can also be applied with an appropriate rectified DC power supply.
Therefore, the first question for buyers should be whether the hydraulic control system requires AC or DC operation. Force and stroke should be evaluated after the electrical architecture has been identified.
For machinery with an established AC control circuit, an MFB configuration can simplify replacement and integration. For equipment using a PLC-based 24V DC control system, an MFZ configuration may provide a more direct match with the existing electrical architecture.
When an MFB AC Solenoid Makes Sense
MFB1-YC wet-type solenoids are intended for AC control systems and support AC110V and AC220V operating voltages with a 50–60 Hz operating frequency.
An AC configuration can be considered when:
-
The hydraulic control cabinet provides AC power.
-
The directional valve is already controlled through an AC circuit.
-
Existing relays, contactors, or switching components are designed for AC operation.
-
An existing AC solenoid needs to be replaced without substantially modifying the control system.
-
The valve's mechanical interface matches the MFB configuration.
For example, when an older hydraulic machine uses an AC220V valve circuit, replacing the original solenoid with another compatible AC configuration can be more straightforward than converting the system to DC.
The key is to match the electromagnetic actuator with the electrical architecture already established in the machine.
When an MFZ DC Solenoid Is Appropriate
MFZ1-YC wet-type solenoids are designed for DC applications and include DC24V, DC110V, and DC220V voltage options.
The 24V DC option is particularly relevant to industrial automation equipment because PLCs, sensors, relays, controllers, and many machine control circuits commonly use 24V DC.
An MFZ configuration may be suitable when:
-
The machine's control voltage is 24V DC.
-
A PLC is used to control the hydraulic valve.
-
The electrical architecture requires a DC actuator.
-
The equipment provides an appropriate rectified DC supply.
-
The solenoid voltage needs to correspond directly with the existing control circuit.
For a hydraulic system already designed around 24V DC, using an MFZ1-YC solenoid with the correct voltage can avoid unnecessary electrical conversion and additional control components.
However, the correct selection should always be based on the actual control circuit rather than hydraulic pressure or valve size alone.
Mechanical Compatibility Is Equally Important
AC/DC selection is only the first step. The solenoid must also meet the mechanical and electromagnetic requirements of the hydraulic valve.
The MFB(Z)1-YC family is designed for conventional 6-diameter and 10-diameter hydraulic solenoid directional control valves. Depending on the selected model, rated suction force ranges from approximately 15 N to 70 N, while rated stroke specifications range from approximately 3 mm to 7 mm.
A solenoid with the correct voltage but insufficient magnetic force may not move the valve reliably. Likewise, adequate force cannot compensate for an insufficient stroke.
The required electromagnetic performance depends on the valve mechanism, spring force, hydraulic conditions, internal friction, and required movement. Buyers should therefore compare the solenoid specifications directly with the valve manufacturer's requirements.
Understanding Force and Stroke
The available MFB and MFZ configurations cover several electromagnetic performance levels, including approximately:
-
15 N rated suction force
-
25 N rated suction force
-
30 N rated suction force
-
40 N rated suction force
-
55 N rated suction force
-
70 N rated suction force
The corresponding stroke varies by model and can range from approximately 3 mm to 7 mm.
When selecting a model, engineers should distinguish between rated travel and total stroke. A valve may require a specific movement distance to complete its switching action, so both parameters should be checked before installation.
A practical selection should therefore consider voltage, electromagnetic force, rated travel, total stroke, valve diameter, mounting dimensions, and operating requirements together.
Continuous-Duty Operation and Thermal Considerations
Both MFB1-YC and MFZ1-YC configurations are specified for a 100% duty cycle, making them suitable for hydraulic equipment where the solenoid may remain energized for extended periods.
Continuous operation still requires appropriate electrical and thermal management. The stated permissible supply voltage fluctuation is from -15% to +10% of the rated voltage. Keeping the actual supply within the specified range helps maintain stable electromagnetic performance.
The series uses full-copper coils, which support electrical conductivity and heat dissipation during operation. For machines operating through long production shifts or performing frequent valve actions, the temperature around the coil and the overall cabinet ventilation should still be evaluated.
Operating frequency is another factor. Most models in the supplied range support up to 7,200 operations per hour, while the larger 7-size model is specified for up to 3,600 operations per hour. The selected model should therefore correspond to the actual switching frequency of the hydraulic system.
Check Valve Compatibility Before Purchasing
Selecting a solenoid only according to its voltage is a common source of replacement problems. Before ordering, buyers should verify the complete valve and solenoid interface.

Electrical connector and wiring arrangement
The MFB(Z)1-YC series is designed for 6-diameter and 10-diameter hydraulic electromagnetic directional valves and supports specifications associated with Taiwan-made hydraulic valves.
This can be useful for replacement projects involving Taiwan-origin or Taiwan-style hydraulic equipment. Nevertheless, compatibility should be confirmed using the actual valve model, technical drawing, or existing solenoid rather than assuming that similarly named components will have identical interfaces.
Applications for Hydraulic Equipment Manufacturers
The MFB(Z)1-YC series can be considered for hydraulic machinery where electromagnetic directional valves are used to control hydraulic flow.
Potential applications include industrial hydraulic equipment, automated machinery, machine tools, production equipment, material handling systems, and other systems requiring electrically controlled hydraulic actuation.
For OEM applications, the solenoid should be selected during the valve and control-system design stage. For maintenance projects, the existing valve and electrical circuit provide the starting point for identifying a suitable replacement.
The AC/DC choice, valve diameter, force, stroke, mounting dimensions, duty cycle, and switching frequency should all be verified before finalizing the configuration.
Why Direct Manufacturer Supply Can Help B2B Buyers
For hydraulic equipment manufacturers and distributors, supply consistency can be just as important as technical compatibility. Repeated production programs require stable specifications, predictable lead times, and consistent product quality.
Wuxi Huilifu Intelligent Technology Co., Ltd. focuses on the R&D, manufacturing, and sales of electromagnets and electromagnet coils. Its technical background is connected with the powder metallurgy manufacturing experience of Wuxi Jincheng Powder Metallurgy Co., Ltd., which was established in 2003.
The company operates a production base of approximately 2,500 square meters with dedicated R&D, manufacturing, testing, and warehousing areas. Precision processing and performance testing capabilities support the production of electromagnetic components for different industrial applications.
For B2B customers, factory-direct supply can be useful for recurring replacement orders and OEM production programs. The stated lead time for the relevant supply arrangement is approximately 15 working days, with export shipments available through major ports such as Shanghai and Ningbo. Actual schedules should be confirmed according to order volume and production requirements.
Non-standard electromagnetic requirements can also be discussed where standard models do not completely satisfy an application. Providing the valve model, rated voltage, force, stroke, dimensions, duty cycle, and operating environment at the inquiry stage can make technical evaluation more efficient.
A Simple Process for Choosing MFB or MFZ
The selection process can be organized into several practical steps.
First, identify the valve. Confirm whether the application uses a 6-diameter or 10-diameter hydraulic directional control valve and obtain the original model information if possible.
Second, identify the control voltage. Choose the MFB1-YC series when the application requires AC110V or AC220V. Select the MFZ1-YC series when the system requires a suitable DC voltage such as DC24V, DC110V, or DC220V.
Third, verify electromagnetic performance. Compare the valve's required actuation force and movement with the solenoid's rated suction force, rated stroke, and total stroke.
Fourth, review operating conditions. Check duty cycle, switching frequency, voltage fluctuation, hydraulic pressure, ambient conditions, and thermal requirements.
Finally, confirm mechanical compatibility. Mounting dimensions, valve interface, coil configuration, and connector arrangement should be checked before placing a bulk order.
This method helps avoid situations where the purchased solenoid has the correct voltage but cannot physically or mechanically operate the intended hydraulic valve.
MFB vs. MFZ: Which Configuration Should You Choose?
There is no universal winner between MFB and MFZ. The appropriate choice depends primarily on the electrical architecture of the hydraulic equipment.
MFB1-YC is the natural option for compatible AC control systems, including applications using AC110V or AC220V. MFZ1-YC is intended for DC control systems and provides options such as DC24V, DC110V, and DC220V.
Once the electrical type is established, buyers should continue by checking valve diameter, suction force, stroke, mounting dimensions, duty cycle, operating frequency, and actual valve compatibility.
For OEM production, replacement maintenance, and hydraulic equipment distribution, the MFB(Z)1-YC Series Wet-Type Solenoids for Valves provides both AC and DC configurations for conventional hydraulic directional valve applications. By matching the electrical system first and then verifying mechanical and operating parameters, users can reduce installation risks and simplify component selection.
For bulk procurement or applications requiring customized electromagnetic components, Wuxi Huilifu Intelligent Technology Co., Ltd. can provide factory-based technical coordination and production support. The MFB(Z)1-YC Series Wet-Type Solenoids for Valves can therefore be evaluated as a practical option for hydraulic machinery manufacturers, system integrators, distributors, and replacement projects requiring dependable electromagnetic valve actuation.
