O453P
High-pressure solenoid valve · 2/2 normally open · Pilot-piston
DEMA O453P is a 2/2 normally open pilot-piston high-pressure solenoid valve with a brass body and PTFE seal: open when de-energized, closed when energized, for high-pressure spray and water circuits that must stay open on power loss. Because the pilot port sits in a chamber separate from the piston, the plunger works closer to the top plug with greater force and a higher opening pressure. Differential pressure 10–1000 psi; an 80-mesh strainer is recommended ahead of the valve, and a DC coil must be derated to 900 psi. Confirm coil voltage and configuration code; price, lead time and availability are subject to confirmation.
