Normally Closed High Pressure Valves

DEMA’s high pressure valves are designed for pressures from 10 psi up to 1200 psi, are available for 3/8-1” pipes, have orifices from 11/32-15/16” 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.
