Constructed from brass and suited for many applications as it has a 7/8″ ODF inlet and outlet from the valve. It is suitable for use in a broad temperature spectrum of -58°F to 311°F, thus flexibility in environmental conditions. The working pressure of this model is 710 PSIG and it provides high pressure and high performance. This specific valve helps to avoid back flow in the system and this is crucial, because, if a back flow occurs in the system either the system will be damaged or its efficiency will be lowered in the process.
