OCV 1330

The OCV 1330 is a two-way, normally closed pilot, that senses pressure under its diaphragm and balances it against an adjustable spring load. An increase in pressure above the spring set point, tends to make the pilot open. The OCV 1330 is the standard pilot for OCV Series 108 Pressure Relief/Sustaining Valves. Sensing upstream pressure and opening at the set point, modulates the main valve to maintain the required pressure. There are other applications for the pilot as a normally closed, pressure to open control.
