Pressure Reducing Valve 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.

Pressure Reducing Valve 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.

Sizes: 1/2"- 4"
End Connection: NPT ANSI 125 flanged. NPT ANSI 300 flanged.
Material: Cast Iron, Cast Steel

Downstream Pressure Ranges
For the following downstream pressures, three color-coded pilot valve springs are available:
Yellow: 3 to 30 psi
Blue: 20 to 100 psi
Red: 80 to 250 psi

Installation
The regulator should be installed in a horizontal line with suitable bypass and isolating valves. A steam trap should be installed upstream to prevent condensate from reaching the regulator. The trap and regulator should both be protected with a strainer. The pressure sensing line should be located in a straight section of the downstream piping at least 10 pipe diameters from the nearest fitting.
