Key Benefits and Advantages
-
Space-Saving Construction: The compact, vertical design allows these relief valves to be installed in tight piping configurations or small enclosures where larger relief devices would not fit.
-
Economical Protection: Provides a cost-effective solution for overpressure protection in systems where a high degree of relieving precision is not required, making it ideal for high-volume deployments.
-
Durable Build Quality: Constructed to withstand the rigors of outdoor installation, the H200 Series is designed for long-term exposure to the elements without compromising safety performance.
-
Protective Cap: Each unit comes equipped with a protective cap that prevents rain, snow, and debris from entering the valve and interfering with the spring mechanism or seating surface.
-
Simplified Operation: The direct-operated “pop” action provides immediate response to overpressure events, ensuring that downstream piping and components are protected from surges.
-
Wide Spring Selection: Available in a variety of factory-preset ranges to match the specific pressure limits of different gas distribution networks.
Technical Properties
-
Operation: Direct-operated pop-style relief.
-
Configuration: Preset and pinned spring retainers to prevent unauthorized or accidental setpoint changes.
-
Media Compatibility: Optimized for natural gas, air, and propane service.
-
End Connections: Typically available in 1/4-inch, 3/4-inch, or 1-inch NPT threaded inlets.
-
Venting: Designed for atmospheric discharge.
-
Adjustability: Factory set to specific pressures to ensure safety compliance in the field.
Field of Application
The H200 Series is specifically designed for use in utility and distribution systems where simple, dependable relief is required. It is the industry standard for secondary safety in rural gas sets.
Primary Industries and Uses:
-
Farm Tap Installations: Providing overpressure protection for residential gas service pulled directly from high-pressure transmission lines.
-
Agricultural Gas Systems: Relief for propane or natural gas lines serving grain dryers and heaters.
-
Small Industrial Skids: Secondary safety for air compressors or small-volume gas manifolds.
-
Gas Distribution: Used as a backup relief device on low-pressure distribution headers.
