Safety Relief Valve SRV 155 D - Peppas Ltd

1 ApplicationsThe 155 D Relief Valve is used downstreamof pressure regulators to Relief limitedvolumes of gas. Used where venting toatmosphere is acceptable, it provides costeffective solution to avoid triggering safetyshutoff valves in case of creep leaks fromregulators. This Valve is ideal for mediumpressure settings and offers a wide settingrange and good 155 D Relief Valve is a spring-loadedthrottling Relief Valve , where a diaphragmmeasures the system (inlet) pressure, aspring provides the initial load to the diaphragm and establishes the Relief setpoint and a Valve throttles the Relief Relief ValveSRV 155 D< Accurate operation< Tight shutoff< Durable<Approved by German DVGW<SRV 155 DBody Sizes & ConnectionsMaterialsBodyGGG 40 ActuatorGGG 40 OrificeBrassInternal partsBrass, Steel, zinc coatedSeals / O-RingsNBR rubber / Viton DiaphragmNBR rubber, fabric reinforcedMaximum Relief (inlet)
