Custom properties
A standard solenoid valve works fine in a normal factory. Put it in a petrochemical plant, a mine, or an oil refinery, and it becomes a liability.
The coil can spark. The terminals can arc. In an explosive atmosphere, that spark can ignite the surrounding gas or dust. You don't want that.
The G1WE Series Hydraulic Directional Valve solves it. Same directional control function as a standard valve. Same spool, same ports, same flow. But with a flameproof enclosure around the solenoid and electrical connections. If a spark occurs inside, the enclosure contains it. The flame doesn't get out.
NG6 size. 80 L/min. 31.5 MPa at P/A/B, 16 MPa at T. DC12V/24V or AC110/220V. Spool types E, J, H, G, D, Y.

Installation - what matters
Mounting. Standard NG6 / CETOP 03 subplate. Check the porting pattern matches your manifold.
Electrical. Certified flameproof cable glands. The gland is part of the certification - not just a seal. Use the right cable type and sealing method.
Flame path. Don't modify the flame path surfaces. If the gaps are damaged, the valve is no longer safe to use.
Maintenance. If you open the enclosure, check the flame path gaps before putting it back together. If they're out of spec, the valve goes back to the factory for repair or recertification.
Coil replacement. Certified coils only. A standard coil from a non-explosion-proof valve won't maintain the certification.
Where it belongs
The G1WE Series Hydraulic Directional Valve is used in hydraulic systems located in hazardous areas:
Petrochemical plants - flammable gas and vapor atmospheres
Mining equipment - methane and coal dust hazards
Offshore platforms - oil and gas environments
Chemical processing - flammable solvents
Paint and coating facilities - solvent vapors
Grain handling - combustible dust
About the company
Shijiazhuang Laiye Import & Export Trading Co., Ltd., part of Hebei Onederful® Hydraulic Technology Co., Ltd., has been making hydraulic components since 1988 - over 35 years.
We're a factory, not a trading company. Around 200 employees. Full in-house production: casting, machining, assembly, testing, phosphating.
Products go to Russia, Europe, the Middle East, South America, and Asia. ISO 9001 certified. Every valve is tested individually, with data linked to its serial number.
Production process
Raw Material Inspection
Cast iron and alloy steel come in. We check composition and mechanical properties before anything else.
Precision Machining
CNC machines handle milling, drilling, grinding, and honing. Tight tolerances on bodies, spools, and end covers. After machining, parts get deburred, cleaned, and measured. For explosion-proof valves, the flame path surfaces are machined to precise gap tolerances.
Heat Treatment
Spools and valve seats get hardened. Better wear resistance, longer service life.
Surface Treatment
Phosphating or other rust-proof coatings go on. Protects against corrosion, improves surface durability.
Assembly
Spools, springs, seals, and control parts go in sequence. Torque controlled on every connection. For explosion-proof valves, the flameproof enclosure is assembled carefully to maintain the specified gap clearances.
Pressure Testing
Every assembled valve gets hydraulic tested - pressure resistance, leakage detection, functional debugging at rated working pressure.
Final Inspection
Visual check. Dimensions confirmed. Test data reviewed. Each valve tested individually, not spot-checked. Test data tied to the serial number.

FAQ
Q: What kind of valve is the G1WE, and what are its key features?
A: The G1WE series is a cost-effective and versatile direct-acting solenoid directional control valve designed for light-to-medium-duty hydraulic systems, such as those found in material handling equipment, packaging machinery, and agricultural implements. Featuring a simplified direct-acting solenoid design, it offers low internal pressure drop and high switching efficiency, enabling precise control over the directional movement of hydraulic cylinders and motors.
Q: What distinguishes the G1WE from standard solenoid directional valves?
A: The G1WE series features a simplified direct-acting solenoid design, offering low internal pressure drop, high switching efficiency, and reduced energy consumption. Its die-cast aluminum alloy housing provides excellent corrosion resistance, making it suitable for light- to medium-duty applications.
Q: Can the G1WE series operate in harsh environments?
A: Yes. Its die-cast aluminum alloy housing offers excellent corrosion resistance, and the highly wear-resistant seals maintain stable performance even in high-temperature and contaminated environments, making it suitable for continuous use in light-to-medium industrial applications.
Q: Is the G1WE series easy to install and maintain?
A: Yes. Its direct-acting design is simple and has fewer potential points of failure. The mounting interface complies with international standards, allowing for direct replacement of existing valves of the same specifications. The coil is detachable, so the valve body does not need to be removed during replacement.
Q: Why does the G1WE series offer low energy consumption?
A: It features a direct-acting solenoid design with optimized internal flow paths, resulting in minimal pressure loss. Unlike pilot-operated valves, it does not require a continuous supply of pilot oil, and the solenoid consumes less power during switching.
