The Model 2400 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 Model 2400 is the standard pilot for OCV Series 108HP Pressure Relief/ Sustaining Valves. Sensing upstream pressure and opening at the set point, it modulates the main valve to maintain the required pressure.
There are other applications for the Model 2400 as a normally closed, pressure to open control.
Model 2400 Pressure Relief Pilot:
Stainless Steel ASTM A743/CF8-M
Elastomers (diaphragm, seat disc, o-rings)
200 – 750 psig / 1380 – 5170 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.
