2-way Gate Type Process Solenoid Valve 526G


This gate type design uses spring loaded seal discs that seal tightly at all pressures from 0 psig to maximum rating. Extreme reliability is inherent due to the rugged design and simplicity of operation and a minimum number of moving parts. Isolation standoffs prevent excessive heat transfer to the solenoid operator. Because of the straight-through flow path with self-cleaning sealing surfaces, internal passages inherently resist any build-up of contamination and sludge. Compact, lightweight design provides excellent resistance to seismic vibration and shock. A completely enclosed and encapsulated coil ensures continuous operation during LOCA event.
