ITRON SRV811

ITRON SRV811

The Itron SRV 801 and 811 relief valves are ideal for low pressure settings due to the increased sensitivity provided by a large diaphragm area. They provide a cost-effective solution to prevent safety shut of valves from triggering in case of thermal expansion, transient pressure surges and creep leaks from regulators.

The Itron SRV801/811 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.
