USG Safety Relief valves offer an economical installation for large capacity relief applications. And that’s exactly the solution you need when other devices in the system don’t relieve dangerous overpressure in the transmission, distribution, and use of gas. Leaking bypass valves can sometimes permit pressure to build during off-peak hours. Pressure regulators with damaged valves or seats are not able to effectively shut off when required, possibly leading to dangerous conditions.

USG mechanical safety relief valves are an economical solution with large relieving capacity. The Model 250-S and 250-DW valves incorporate a deep molded diaphragm and offer an angled body with a large exit area for a high flow rate.
