What Makes This Valve Different
Most solenoid valves are not safe in explosive atmospheres. That's the problem the G1WE6 solves.
It's an explosion-proof valve - Exd certified. That means the coil is designed to contain any internal spark or heat. Nothing escapes to ignite the surrounding gas, dust, or vapor. In a coal mine or an oilfield, that's the difference between safe operation and a disaster.
The G1WE6 looks like a standard 4WE6 solenoid valve. Same NG6 size. Same ISO 4401 mounting. Same 80 L/min flow and 315 bar pressure. But inside, the coil is built differently - it's certified for hazardous environments.
If your equipment operates where flammable gas, dust, or explosive mixtures are present, this is not an option. It's a requirement.
For applications that demand safety in hazardous environments, the Explosion Proof Valve Have Certificate is the right choice.
A Closer Look
Exd Certification - What It Means
Exd is the international standard for explosion-proof equipment. The "d" stands for "flameproof" - the enclosure contains any internal explosion, preventing it from igniting the outside atmosphere. In practical terms, this means the valve can operate safely in areas where flammable gas or dust is present.
Direct-Acting - No Delay
The solenoid moves the spool directly. No pilot stage to wait for. The valve shifts as soon as power is applied.
Wet-Pin Solenoid - Replaceable Coil
The coil is a wet-pin type - it sits in oil, which keeps it cool. And it's removable. If the coil fails, you don't replace the whole valve - just the coil. Loosen a nut, pull it off, slide the new one on. No disassembly. No oil leak.
NG6 Size - Standard and Compact
NG6 is the most common size for small directional valves. Fits standard subplates. No custom adapters.
80 L/min at 315 bar
80 L/min flow and 315 bar pressure - the same as the standard 4WE6. You're not giving up performance for safety.

Product application
Based on its explosion-proof certification, the Explosion Proof Valve Have Certificate is required in hazardous environments where standard valves would be unsafe:
Coal Mines
Underground mining equipment - where methane gas and coal dust create explosive conditions. The Exd-rated coil ensures safe operation.
Oil and Gas Drilling
Drilling rigs, wellhead control systems - where flammable gases are present. The explosion-proof design prevents ignition from electrical sparks.
Chemical Plants
Process control systems, chemical reactors - where volatile chemicals and explosive vapors are common.
Offshore Platforms
Subsea control systems, platform hydraulic equipment - where explosive gases may accumulate in confined spaces.
Petrochemical Facilities
Refineries, storage facilities - where flammable liquids and gases are handled daily.
Installation and Care
Installation
Mounting surface is ISO 4401. Use a compatible subplate. Before installation: depressurize the system. Disconnect power. Clean the lines - dirt causes spool sticking. Check O-rings for damage. Don't overtighten mounting bolts.
Important: Verify the model, voltage, and explosion-proof certification match your site requirements. Installation must follow safety regulations for hazardous area equipment.
Electrical
Confirm voltage matches your supply - DC 12V or 24V. Check polarity on DC models. Use properly rated cable and connectors for hazardous area installations.
Coil Replacement
The coil is detachable. Loosen the retaining nut, pull it off, slide the new one on. No disassembly. No leakage. Make sure the replacement matches the original voltage and power ratings.
First Start
Check model and voltage. Start at low pressure and look for leaks. Cycle the valve a few times.
Common Issues
Won't shift: Check voltage. Check polarity on DC models. Test coil resistance. Check for contaminated oil.
Slow or jerky: Dirty oil. Check filter.
Leaking: Check O-rings and mounting bolts.

Our production and equipment
Raw Material Inspection
Iron castings and steel arrive with mill certificates. We verify each batch through spectral analysis for material composition and inspect for internal defects. Any material that doesn't meet spec gets rejected at the door.
↓
Precision Machining
Each valve body goes to the CNC machining center. The G1WE6 is a solenoid valve - the body is machined as a single piece with spool bores, mounting surfaces, and porting all completed in one setup. Tolerances are held to microns.
↓
Heat Treatment
Once machined, the bodies go through heat treatment. This relieves internal stress from the cutting process, improves wear resistance, and locks in dimensional stability.
↓
Spool Grinding
Each spool is precision-ground to final dimensions. Clearances are held to tight tolerances - this determines internal leakage performance.
↓
Explosion-Proof Coil Assembly
The explosion-proof coil is assembled and tested separately. Each coil undergoes rigorous testing to verify Exd certification compliance - spark containment, heat resistance, and enclosure integrity.
↓
Assembly
The valve body, spool, springs, seals, and explosion-proof solenoid coil are assembled. Each assembler stamps their work for traceability.
↓
Pressure Testing
Every valve is individually tested - not spot-checked. Pressure tests, seal integrity checks, and flow performance tests are performed. Test data is filed against the serial number.
↓
Final Inspection & Packaging
One last check - appearance, marking, certification label, packaging. If it passes, it goes to inventory. If it doesn't, it goes back. We don't ship valves we wouldn't use ourselves.

FAQ
Q: What is the G1WE6 series valve?
A: The G1WE6 is an explosion-proof hydraulic solenoid directional valve, designed for use in hazardous environments where flammable gas, dust, or explosive mixtures may be present.
Q: How does it operate?
A: It is a direct-acting solenoid valve. The solenoid directly pushes the spool to shift positions, controlling the direction of hydraulic fluid flow. The coil is a wet-pin type, removable design, ensuring the pressure chamber is filled with oil for proper operation.
Q: Can the coil be replaced separately?
A: Yes. The explosion-proof coil is detachable and can be replaced by loosening the retaining nut-without opening the pressure-tight chamber or causing oil leakage.
Q: What should be checked before installation?
A: Verify the model, voltage, and explosion-proof certification match your site requirements. Ensure the mounting surface meets ISO 4401 standards. Clean piping thoroughly to avoid contamination. Installation should follow safety regulations for hazardous area equipment.
Q: What if the solenoid is energized but the valve doesn't shift?
A: Check power supply voltage, inspect the coil (test resistance), and confirm the spool is not stuck due to fluid contamination. Keep hydraulic fluid clean.
