V70900-39 Air Pilot Operated Solenoid Valve

Air Pilot Operated Solenoid Valve 70900-39

Description

This ruggedly built three way valve is designed to meet all the requirements for in containment vessel service as an air system pilot valve for other safety related valves. It is qualified to the latest IEEE 323 requirements for active valves. A NEMA 4 Type solenoid enclosure ensures that the coil assembly will withstand the steam, pressure, boric acid/ sodium hydroxide spray, temperature and radiation requirements of a LOCA situation. The valve element is a simple direct acting poppet type which does not require a minimum differential pressure. It will seal bubble tight at operating pressures to 150 PSIG. The seats are positively retained to insure reliable sealing under all operation conditions. There are no dynamic seal leakage points to the environments.
