The 25P is a self actuated pilot operated pressure regulator downstream pressure is fed back through an external sensing line to the pressure pilot, which adjusts the opening of the main valve so as to maintain the set pressure the main valve can close tight for ANSI/FCI 70-2 Class IV shut off when steam is not required. The 25P is a reliable, accurate regulator to reduce steam from a high supply pressure to the most efficient operating pressure of the equipment, and to protect the equipment from dangerously high pressures.

Pressure Pilot, Series/Model: Model 25P, Connection Type: Flanged, Pressure Rating: 20 - 100 PSIG, Material: Cast Iron, Finish/Color: Blue Spring

• Pressure pilots open and close the main valve by sensing the flow of steam through them, controlled by a pressure spring
• The pressure range of the pilot is adjustable within its presets by an adjustment nut on the top of the unit
• The pilot has a downstream sensing line which tells the valves to put more pressure on the main valves diaphragm to open and allow more steam to pass
• As the demand is met, the pilot relieves the pressure on the main valve diaphragm causing it to throttle to the closed position

Application: For pressure pilots on 25 series with combination main valves
