Overview
It ensures stable pressure supply to burners, appliances, and equipment, preventing damage from over-pressurization and optimizing fuel efficiency. Constructed with corrosion-resistant materials and advanced sealing technology, this valve withstands extreme temperatures and harsh environments, ensuring long-term reliability.
Features
Precision Pressure Regulation: Maintains outlet pressure within ±5% of the setpoint, even under fluctuating inlet pressures .
Wide Pressure Range: Handles inlet pressures up to 20 bar (290 psi) and outlet pressures from 0.1–5 bar (1.4–72.5 psi) .
Freeze Protection: Integral thermal insulation prevents ice formation during rapid pressure reduction in cryogenic applications like LNG storage .
Fail-Safe Design: Spring-loaded diaphragm ensures the valve closes automatically in case of downstream pressure loss.
Easy Adjustment: External pressure regulator allows quick setpoint changes without disassembling the valve.
Multi-Port Configurations: Available in 1/2" to 2" connections for diverse pipeline sizes.
Application
Industrial Gas Systems: Regulates pressure in welding, cutting, and heat treatment processes.
Commercial Kitchens: Supplies stable pressure to gas stoves, ovens, and fryers in restaurants and hotels.
Residential Heating: Controls pressure in home furnaces, water heaters, and outdoor grills.
LNG Storage: Reduces pressure in cryogenic tanks for safe distribution .
Marine Applications: Manages fuel pressure in shipboard LPG systems.
FAQ
Q: How do I adjust the outlet pressure?
A: Loosen the locknut, turn the adjustment screw clockwise to increase pressure or counterclockwise to decrease, then retighten the locknut .
Q: Can the valve be used with corrosive gases?
A: Yes, select models with 316 stainless steel bodies and Viton seals for compatibility with acidic or caustic gases.
Q: What causes pressure fluctuations?
A: Common causes include clogged filters, worn diaphragms, or incorrect spring tension. Regular maintenance and filtration prevent these issues.
Q: How often should the valve be inspected?
A: Inspect every 6 months or after 1000 operating hours. Check for leaks, diaphragm wear, and proper spring tension.
Q: Does the valve require external power?
A: No, it operates purely mechanically, making it suitable for remote or off-grid applications.
