Normally Closed High Pressure Valves

Normally Closed High Pressure Valves
Normally Closed High Pressure Valves
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.
