Relief Valves
Relief Valves
Provide critical over-pressure protection for gas systems, helping prevent equipment damage and unsafe operating conditions
257-S, 250-S, and 250-DW
We have three relief valve models available to meet your capacity requirements: 257-S, 250-S, and 250-DW. They were created to protect gas systems from dangerous over-pressurization in transmission, distribution, metering, and industrial applications. They add an extra layer of security to a utility's natural gas system by automatically venting excess pressure to the atmosphere when there is a leak or failure in the pressure regulation.
Features & Benefits
Designed to safely discharge excess gas volume and maintain pressure below predetermined limits.
The weatherproof and watertight construction makes the valves suitable for indoor or outdoor installations in utility and industrial environments.
Protects downstream piping, meters, and equipment from over-pressurization events.
No external power or controls required. The valve operates automatically based on system pressure.
