Key Benefits and Advantages
-
High Capacity Performance: Despite its compact design, the HSR provides exceptional flow rates, ensuring consistent gas supply even during peak demand periods.
-
Integrated Safety: Features high-capacity internal relief across the diaphragm to help minimize overpressure. If the outlet pressure exceeds the start-to-discharge point, the diaphragm moves off the relief valve seat to vent excess pressure safely.
-
Versatile Body Configurations: Available in both globe and angle body styles, allowing for flexible installation in various piping layouts and meter sets.
-
Precision Accuracy: Meets or exceeds Fixed Factor / PFM (Pressure Factor Measurement) accuracy requirements, ensuring precise billing and stable downstream pressure for gas appliances.
-
Industry Compliance: Fully meets the rigorous standards of ANSI B109.4 and CGA 6.18, providing peace of mind regarding structural integrity and operational safety.
-
Durable and Compact: The streamlined housing is built to withstand outdoor environmental exposure while fitting into tight spaces, such as residential meter enclosures.
Technical Properties
-
Operation: Direct-operated and spring-loaded for immediate response to load changes.
-
Media Compatibility: Suitable for natural gas, LP gas, and manufactured gases.
-
Body Sizes: Typically available in 3/4, 1, and 1-1/4 inch NPT end connections.
-
Internal Relief: Non-adjustable relief valve spring designed for consistent overpressure protection.
-
Orifice Sizes: Multiple orifice options available to optimize the regulator for specific inlet pressures and required flow capacities.
Field of Application
The Type HSR is the standard solution for domestic and light commercial gas service. Its ability to provide stable pressure to appliances makes it a staple for utility companies and HVAC professionals.
Primary Industries and Uses:
-
Residential Gas Service: Standard pressure reduction for homes and small apartment complexes.
-
Commercial Establishments: Gas supply for restaurants, small boilers, and rooftop units.
-
Industrial Utilities: Low-pressure gas feed for localized process heaters or pilot lights.
-
LP Gas Systems: Pressure regulation for propane tank installations.
