The SRV 811R safety relief valve is installed downstream of pressure regulators to relieve limited volumes of gas. Used where venting to the atmosphere is acceptable, it provides a cost-effective solution to prevent safety shut-off valves from triggering in case of creep leaks from regulators. This valve is design for indoor installation and is ideal for low and medium pressure settings.

KEY BENEFITS
» Compact design
» Accurate operation
» High flow capacity
» Easy maintenance
» Reliable
» Tight shut-off

DESCRIPTION
The SRV 811R safety relief valve is a spring loaded throttling relief valve, where a diaphragm measures the system (inlet) pressure, a spring provides the initial load to the diaphragm and establishes the relief set point, and a valve throttles the relief flow.
