All valves satisfy the requirements of NFPA 58 and can be used in stationary applications. All Cavagna internal valves have a robust, one piece body design and an incorporated excess flow function. Each valve has a weak section that allows the pump or piping to “shear” in the event of an accident, thereby leaving the valve mechanism intact. Cavagna threaded valves are compact and can be operated either manually or remotely via cable or pneumatic control. Valves contain spring-loaded, PFFE packing providing excellent leakage protection and the standard disc material provided is Nitrile.
