The Model 1330XS is a two-way, normally closed pilot, that senses minute pressure changes 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 Model 1330XS is the standard pilot for OCV Series 108XS Pressure Relief/ Sustaining Valves. Sensing upstream pressure and opening at the set point, the pilot modulates the main valve to maintain the required pressure.
Mode 1330XS Pressure Reducing Pilot:
1. Adjusting Screw Cover
