The Model 1340XS is a two-way, normally open 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 close.
The Model 1340XS is the standard pilot for OCV Series 127XS Pressure Reducing Valves. Sensing downstream pressure and closing at the set point, the pilot modulates the main valve to maintain the required pressure.
Model 1340XS Extra Sensitive Pressure Reducing Pilot:
Elastomers (diaphragm, seat disc, o-rings)
1-15 psig / 7-105 kPa
Rubber components are typically the only parts that may require periodic replacement. These are available in kits consisting of the diaphragm, the seat disc and all O-rings.
Buna-N Kit – Part # 930014
