DEMA 458 Series Brass High Pressure SS Piston 1" 1200 PSI Normally Closed Solenoid Valves

DEMA Series 458 high pressure valves are designed for pressures from 10 psi up to 1200 psi on 1" pipe and are intended for use with water only. They operate the same as a pilot operated valve except the pilot port is in a separate chamber from the piston. This allows the plunger to operate closer to the top plug with more force and consequently higher opening pressure.

Series 458P valves feature a stainless steel piston, and 458PS valves features both a stainless steel piston and a stainless steel sleeve.
