V Series Relief Valves V/50 and V/60 Series Spring-Loaded Relief Valves The spring-loaded relief valves are designed to keep line pressure below preset values. They are mounted downstream of regulators and perform the specific function of releasing small amounts of gas in the event of the regulator not closing perfectly. Thanks to their effective release capacity and compact size, the V/ series relief valves are ideal for use in civil and industrial equipment. The valves are extremely easy to install and are designed for ready and easy maintenance. The V/50 and V/60 series relief valves are...

V Series Relief Valves Applications The relief valves V/50 and V/60 series can be used with natural gas, manufactured gas, air, propane and other gases, as long as they do not contain a high percentage of benzol. V/50 and V/60: for very low pressure applications V/52 and V/62: for middle pressure applications Seat diameter Threaded connections Standard version Body/Cover Aluminium Valve seat Brass Diaphragm Fabric NBR nitrile rubber Gaskets NBR nitrile rubber

V Series Relief Valves V/20-2 Model Spring-Loaded Relief Valves The V/20-2 relief valves are designed for use at medium and high pressures and cover a wide range of setting values (1.5 to 40 bar). To change setting, simply replace the spring with the one appropriate for the desired value. Operation Whenever gas pressure under pad (O) is higher than the force exerted by spring (M) in the opposite direction, pad older device (P) is raised, thereby causing the release orifice to open. G Setting is carried out by adjusting the compression of spring (M) through the appropriate ring (G). It is...
