Product Definition
Power the solenoid, and it pushes the spool to shift the oil flow. Cut the power, and the spring pushes it back. That's how a solenoid valve works.
Now add a handle.
Move the handle, and it physically pushes the spool. No power. No pilot pressure. No electronics. Just a mechanical link that works when nothing else will.
That's the WEMM6 Solenoid Directional Valve with Handle. Two ways to control the valve. Solenoid for daily operation. Handle for emergencies.
If power fails, the machine doesn't stop. You shift the handle, keep the equipment running. NG6 size. 80 L/min. 315 bar. Direct-acting solenoid with 20-50ms response.
What you get with this valve
A solenoid valve that works normally. Direct-acting. 20-50ms response. No pilot delay. Energize the coil, the spool shifts. De-energize, the spring returns it.
A manual override that actually works. Not a recessed pin you need a tool to reach. An exposed handle you can grab and move. No power required. No tools. Just your hand.
Coil replacement without disassembly. Loosen the retaining nut, swap the coil, tighten it back. No oil leakage. No taking the valve apart. Five minutes of work.
Multiple options to fit your machine. 4/3, 3/2, or 2/2-way spool. O, Y, H, or other center positions. DC12V, DC24V, AC110V, AC220V. NBR or FKM seals.
When you need manual override
Manual override isn't just for emergencies. It's useful in several situations.
Power failure. The machine loses power. The solenoid can't shift the spool. The manual handle lets you shift it by hand - emergency lowering of forks, retracting booms, releasing pressure.
Commissioning. You're setting up the machine. You need to test the hydraulic circuit. Instead of wiring up the solenoid and applying power, you just move the handle. Faster, simpler.
Solenoid failure. The coil burns out. You don't have a spare. The manual handle lets you keep the machine running until you can replace the coil.
Maintenance. You need to shift the valve without energizing the system. The handle gives you direct mechanical control.
If any of these sound familiar, the WEMM6 is worth considering.

Where it belongs
The WEMM6 Solenoid Directional Valve with Handle is for systems that can't afford downtime:
Material handling equipment. Forklifts, stackers, telescopic handlers. Controls lifting, tilting, attachment functions. Manual override allows emergency lowering of forks during power failure.
Mobile machinery. Compact loaders, aerial work platforms, skid-steer loaders. Controls boom movement, slewing, steering. Emergency platform lowering during power loss.
Industrial automation. Automated hydraulic systems, clamping systems, press auxiliaries. Sequential control. Manual override saves time during commissioning.
Installation - what matters
Mounting surface. ISO 4401-03. Flat and clean. Check the valve body for shipping damage before installation. Flush lines clean.
Bolts. M5. Torque to 4.5-6Nm. Tighten diagonally, in stages. Uneven tightening distorts the body and causes leaks.
Handle clearance. Leave enough space around the manual handle so nothing blocks it.
First start. Run at low pressure to bleed air. Filter to ≤10μm.
Maintenance. Check oil cleanliness. Operate the manual handle every 3-6 months to keep it from sticking. Check the solenoid plug for looseness and the coil for moisture. Inspect seals annually.
Wear parts. Coils can be replaced individually. The push-rod seal is a wear part - if it leaks, remove the solenoid and replace the seal. Be careful not to scratch the push-rod surface.
Model Comparison
| Feature | WEMM6 | 4WE6 |
|---|---|---|
| Manual Override | Standard (exposed handle) | Concealed (tool required) |
| Control Method | Solenoid + Manual Handle | Solenoid only |
| Nominal Size | NG6 | NG6 |
| Max. Flow | 80 L/min | 80 L/min |
| Max. Pressure | 315 bar | 350 bar |
| Best For | Circuits requiring emergency backup | Standard directional control |
| Typical Applications | Forklifts, aerial platforms, mobile equipment | Machine tools, industrial hydraulics |
The key difference is the manual override handle-the 4WE6 relies solely on solenoid control and stops working when power fails, while the WEMM6 with handle keeps you in control even without electricity. That extra feature is what makes it the go-to choice for applications where downtime isn't an option.
Why Choose Us
Source Factory with 30+ Years of Expertise
We started in 1988 and have over 30 years of experience making hydraulic valves, with a particular focus on directional control and emergency-override valves. We run our own factory-casting, machining, testing-all done in-house. That way, we control the quality from start to finish.
Precision Manufacturing
Critical part machining accuracy: ±0.005mm. Spools are carburized, quenched, and hard chrome-plated for better wear resistance. Imported seals (Parker) with automated assembly keep leakage under 5 drops per minute.
100% Inspection Before Shipping
Every unit undergoes pressure testing, leakage checks, and switching response testing before shipping-100% inspected, not random sampling. Valve bodies are phosphated with 48-hour salt spray treatment for corrosion protection.
Global Market Recognition
Products exported to over 20 countries-Russia, Europe, Middle East, South America, Southeast Asia. Annual exports exceed 10,000 containers.
FAQ
Q: What is the WEMM6 solenoid valve with emergency handle, and what are its key features?
A: This is a direct-acting solenoid directional valve with a manual override handle for medium-pressure hydraulic systems. It offers dual-control modes: solenoid for precise daily operation and a manual handle for emergency shifting during power failures or solenoid malfunctions-keeping your equipment running.
Q: How do you use the manual override handle?
A: Simply move the handle to shift the spool-no power required. Ideal for commissioning, emergency operation, and backup during outages. No tools needed-just your hand.
Q: What equipment is this valve suitable for?
A: Material handling equipment (forklifts, stackers), mobile machinery (compact loaders, aerial platforms), industrial automation lines, and any medium-pressure hydraulic system requiring reliable directional control and emergency backup.
Q: What is the lead time?
A: Our standard lead time is 10-15 working days. For urgent requirements, please contact our sales team to discuss expedited options.
Q: What is your warranty policy?
A: We offer a 12-month warranty from the date of shipment. Any quality issues arising during normal use are covered.
Q: Do you provide technical support and documentation?
A: Yes, we provide comprehensive technical support, including installation guidance, hydraulic circuit diagrams, and factory test reports with each shipment.
Q: Does the manual handle require regular maintenance?
A: Not normally. However, it's advisable to operate the handle occasionally to prevent sticking-especially in humid or dusty environments. Prolonged inactivity can cause moving parts to rust or seize.
Q: What's the difference between this valve and a standard 4WE6?
A: The main difference is the manual override handle. The 4WE6 relies solely on solenoid control and stops working when power fails. The WEMM6 solenoid directional valve with handle has a manual handle-if power fails, simply shift the handle to keep the valve operating. That's the kind of peace of mind that makes this valve worth considering.
Q: Can the solenoid coil be replaced separately?
A: Yes. The wet-type solenoid coil is detachable-just loosen the retaining nut to replace it. No valve disassembly or oil leakage. Ensure the replacement coil matches the original voltage and power rating.
