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
