What Makes This Valve Different
The 4WEH25 is a pilot-operated valve - not a direct-acting solenoid valve. That distinction matters when you're moving 700 L/min.
In a direct-acting valve, the solenoid has to be big enough to move the spool directly. At 700 L/min, that spool is large, and the forces are high. You'd need a massive solenoid - expensive, power-hungry, and physically large.
The 4WEH25 Valve Electromagnetic 220v 24v takes a different approach. A small solenoid shifts a pilot spool. That pilot spool directs hydraulic pressure to move the main spool. The solenoid doesn't do the heavy work - the hydraulic pressure does. This means a compact, efficient solenoid can control a very large flow.
700 L/min at 350 bar. NG25 size. 4/3-way, spring-centered. IP65 rated. Available in 24V DC or 220V AC.
If you're working with large hydraulic systems - presses, heavy machinery, steel mills - this is the kind of valve you need. Direct-acting valves max out around 80 L/min. For anything above that, pilot operation is the practical answer
One-stop Hydraulic Valve Factory in China
As a professional one-stop hydraulic valve manufacturer in China, we produce a full range of directional, pressure and flow control valves. Featuring stable performance, strict quality control and competitive prices, we support customized solutions and efficient global delivery for machinery and industrial clients.
About our product
We manufacture a full range of hydraulic valves - directional valves (4WE, 4WEH series), solenoid valves, check valves, relief valves, and flow control valves. They go into construction machinery, presses, metallurgical equipment, injection molding machines, and automated production lines.
Quality comes from the details. We use good materials, machine to tight tolerances, and test every valve before it leaves the shop. The result: stable pressure resistance, low leakage, and long service life.
Standard or custom - we do both. If your system has specific requirements, we can build to match.
We ship to Asia, Europe, the Middle East, and beyond. Our customers keep coming back because the valves work, the price is fair, and the delivery is consistent. That's what matters.
Applications
Based on its flow rating and pilot-operated design, the 4WEH25 Valve Electromagnetic 220v 24v typically ends up in:
Hydraulic Presses
Controlling the main cylinder in large forming presses. The 700 L/min flow enables rapid approach and return speeds - faster cycles mean more parts per shift.
Heavy Machinery
Excavators, loaders, cranes - controlling large cylinders and motors. The valve handles the flow demands of the largest machines.
Metallurgical Equipment
Steel mills, rolling mills, forging presses. High pressure, high flow, harsh conditions. The robust construction and IP65 protection are essential here.
Injection Molding Machines
Controlling injection and clamping on large molding machines. The pilot-operated design provides smooth, precise control of large actuators.
Marine and Mining
Offshore and mining applications where reliability is critical and downtime is expensive.
Exhibitions
We actively participate in global top hydraulic and industrial exhibitions to showcase our products and connect with partners. Key shows include PTC ASIA (Shanghai), Asia's largest power transmission fair, IFPE (Las Vegas), the world's leading fluid power expo, and Valve World Düsseldorf. We also join Bauma China, Hydraulik & Pneumatik shows and regional industrial expos in Europe, Asia and the Middle East. These events let us demonstrate our hydraulic valves, share innovations and build long-term partnership worldwide.
About Our Company
Shijiazhuang Laiye Import & Export Trading Co., Ltd., part of Hebei Onederful® Hydraulic Technology Co., Ltd., has been manufacturing hydraulic components since 1988 - over 35 years of experience. We are a factory, not a trading company, with around 200 employees and a full in-house production process covering casting, machining, assembly, testing, and phosphating. Every valve is individually tested, not spot-checked, with test data filed against its serial number for full traceability. We export to more than 20 countries, hold ISO 9001 certification, and offer OEM customization, technical support, and a 12-month warranty. Test reports, material certificates, and certificates of origin are available upon request.
FAQ
Q: What kind of valve is the 4WEH25, and where is it primarily used?
A: The 4WEH25 is an electro-hydraulic directional control valve, consisting of a solenoid-operated pilot valve and a hydraulically operated main valve. It uses a solenoid to actuate the pilot spool, which then directs pilot oil pressure to shift the main spool, thereby controlling the direction of high-volume fluid flow. It supports a maximum flow rate of 700 L/min and is commonly used in high-flow, high-pressure hydraulic systems.
Q: What are the options for control methods and voltages?
A: Control methods include internal and external control, while return flow options include internal and external exhaust. Common voltage ratings are DC 24V and AC 220V; please confirm the voltage specification when ordering-insufficient voltage fails to actuate the pilot valve, while excessive voltage burns out the coil.
Q: Are there any special precautions during installation?
A: Before installation, ensure the system is depressurized and the power is disconnected. Hydraulic lines must be absolutely clean. During installation, ensure the seals are intact and that connections at all ports are free from mechanical stress. When installing multiple valves side-by-side, maintain the minimum required spacing to prevent the solenoids from overheating.
Q: What is the mounting surface standard?
A: The mounting surface of the 4WEH25 complies with the ISO 4401 standard; the subplate must be purchased separately. When installing the subplate, ensure that the port markings align with the markings on the valve body.
Q: What should be considered before initial use?
A: Check that the model is correct before starting up for the first time. Ensure all ports are properly connected or sealed. If the system is equipped with a venting device, bleed the air from the system first. Observe the safety instructions in the operating manual.
