Six ways to think about this valve
When you're looking at an explosion-proof solenoid valve, you're really asking a handful of practical questions. Here's how the G1WE6 answers each one.
1. What makes it explosion-proof?
The solenoid and electrical connections are housed in a flameproof enclosure. If a spark or flame occurs inside-from a coil fault, switching arc, or other failure-the enclosure contains it. The flame path is designed with precise gap clearances that cool escaping gases before they reach the outside atmosphere. This is not a coating. It's a structural design that is tested and certified.
2. What spool types are available-and which one do I need?
Six options: E, J, H, G, D, and Y.
E - closed center, all ports blocked in neutral. For load holding: clamping, presses, cylinders that must stay put.
J - open center, A and B to T. For actuator float: booms, arms, construction equipment.
H - P to T in neutral. For system unloading: energy saving during idle.
G - P to A and B in neutral. For regeneration circuits.
D - P to A in neutral. For single-acting cylinders.
Y - A and B to T. For motor control and smooth deceleration.
If you're not sure which one fits your circuit, send a schematic and we'll confirm.
3. What flow and pressure can it handle?
80 L/min and 31.5 MPa at P/A/B ports. T port is rated at 16 MPa-that's the return line, which sees lower pressure. This covers most industrial hydraulic systems that need directional control in hazardous areas.
4. How do I install it-and what's different from a standard valve?
Mounting is the same-NG6 / CETOP 03 subplate. The bolt pattern is identical to a standard WE6. If you're replacing a standard valve in a hazardous area, the G1WE6 bolts onto the same manifold. No adapter needed.
What's different: the electrical connection. You must use certified flameproof cable glands or conduit. The gland is part of the flame path-not just a seal. Do not open the enclosure with power on.
5. What about maintenance?
The coil is replaceable, but the replacement must also be certified explosion-proof. You cannot use a standard WE6 coil as a replacement-it doesn't have the flameproof enclosure and will break the certification.
Check the enclosure bolts periodically. They must be torqued to the specified value. Loose bolts can break the flame path.
6. What certifications does it carry?
That depends on the configuration-coil type, voltage, and the standard required for your region. We can supply the G1WE6 with ATEX, IECEx, or CNEx certification. Specify your required standard and zone classification when ordering, and we'll confirm availability and provide the relevant certificates.

Installation notes
Mounting
Mount on a standard NG6 / CETOP 03 subplate.
Torque bolts to the specified value. No impact tools-the valve body is certified as a matched assembly.
Loose bolts can break the flame path. This is not just about leaks-it's about safety.
Electrical connection
Use certified flameproof cable glands or conduit. The gland is part of the certification.
Do not open the solenoid enclosure while powered.
Replacement parts
Only use certified replacement coils. Standard WE6 coils will not maintain the certification.
The solenoid tube assembly is a matched unit-don't mix parts from different valves.
Where this valve ends up
The G1WE6 is used wherever hydraulic directional control is needed in hazardous areas. Some typical places:
Mining-underground equipment, shearers, roof supports
Oil and gas-offshore platforms, refineries, wellhead controls
Chemical plants-processing equipment in flammable environments
Paint facilities-spray booths, mixing areas
Grain handling-elevators, milling equipment, dust-laden areas
If your site has explosion risk classifications, confirm the certification and zone rating with our technical team before ordering.
Company background
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 (based on our 2024 annual shipping records), hold ISO 9001 certification, and offer OEM customization, technical support, and a 12-month warranty. Material certificates, test reports, and certificates of origin are available upon request.
Production Process
The manufacturing process for the G1WE6 explosion isolation valve follows the same sequence as standard hydraulic valves, with additional quality controls for the flameproof enclosure. Each step is documented and traceable.
Raw Material Inspection
High-strength cast iron and alloy steel are checked for composition and mechanical properties before anything else happens.
Precision Machining
CNC equipment handles milling, drilling, grinding, and honing to hold tight tolerances on bodies, spools, and end covers. After machining, all parts go through deburring, cleaning, and dimensional verification.
Heat Treatment
Key components such as spools and valve seats undergo hardening to improve wear resistance and extend service life.
Surface Treatment
Phosphating or other rust-proof coatings are applied to protect against corrosion and improve surface durability.
Assembly
Skilled workers install spools, springs, seals, and control parts in sequence, with torque control on each connection. For explosion isolation valves, additional care is taken with the flameproof enclosure assembly to ensure the specified gap clearances are maintained.
Pressure Testing
Every assembled valve goes through hydraulic testing-pressure resistance, leakage detection, and functional debugging under rated working pressure.
Final Inspection
Visual inspection, dimensional confirmation, and test data review. Each valve is individually tested, not spot-checked, with test data filed against its serial number for full traceability. For explosion isolation valves, the flameproof enclosure is also verified to ensure it meets certification requirements.
FAQ
Q: Manufacturer or trader?
A: Manufacturer. We run our own production.
Q: Is the G1WE6 interchangeable with a standard WE6 valve?
A: Hydraulically and mechanically, yes. The mounting pattern is the same NG6 / CETOP 03 footprint. If you're replacing a standard WE6 in a hazardous area, the G1WE6 bolts onto the same manifold. The key difference is the explosion-proof enclosure and certification.
Q: Can I use a standard WE6 coil as a replacement on the G1WE6?
A: No. The replacement coil must also be explosion-proof certified. A standard WE6 coil does not have the flameproof enclosure and will void the valve's certification.
Q: What should I check before installing the G1WE6?
A: Confirm the certification matches your site classification. Use certified flameproof cable glands. Check the enclosure bolts are torqued to the specified value. Do not open the enclosure while powered.
