High Pressure Gas Relief Valve Product Description
The Gas Relief Valve (also known as a proportional relief valve) is a safety device used in gas pipeline systems. It automatically releases gas when the pressure exceeds a set threshold, ensuring stable system pressure and preventing equipment damage or safety hazards. VIGOUR brand relief valves are renowned for their high reliability, precise control, and durability, making them especially suitable for high-pressure gas systems in industries such as manufacturing, energy, and chemicals.
- Ultra-High Pressure Resistance: Supports a maximum pressure of up to 413 bar (about 6000 psi), meeting the demands of extreme high-pressure conditions.
- Precise Proportional Control: Utilizes proportional unloading technology to achieve dynamic pressure regulation, with fast response times and high stability.
- Multiple Safety Protections: Features a built-in redundancy design to prevent system overpressure risks caused by valve failure.
- Wide Applicability: Compatible with various industrial gases such as nitrogen, oxygen, and argon (selection depends on the medium).
- Certifications and Materials: Complies with international safety standards (e.g., ASME, CE), with the valve body made from high-strength stainless steel or special alloys, resistant to corrosion and high temperatures.
- Connection Types: Supports NPT (National Pipe Thread) and Tube Fitting options, catering to different piping connection requirements.
- Size Range: Common connection sizes range from 1/4" to 1" (custom sizes available upon request).
Q: How do I choose between NPT or Tube Fitting connections?
A: Choose based on your existing piping design-NPT is suitable for threaded sealing applications, while Tube Fitting is ideal for precision, threadless tube connections.
Q: What should I consider when installing?
A: Ensure the valve is installed in the correct direction, with the gas flow direction matching the arrow on the valve body. Leave enough space for maintenance, and perform a pressure test after installation.
Q: How can I adjust the set pressure on the relief valve?
A: Use the top adjustment knob or an external control module (available on some models) to calibrate. Monitor pressure in real-time using a pressure gauge.
Q: What should I do if the valve leaks?
A: Check if the sealing rings are worn or the valve seat is contaminated. Replace the seals if necessary. If the leakage persists, contact after-sales support for inspection.
Q: What is the recommended maintenance cycle?
A: For normal conditions, it is recommended to check the high pressure gas relief valve's sealing and response sensitivity every 6-12 months. In harsh environments, the maintenance cycle should be shortened.
