Spirax Sarco 25P Pressure Reducing Valves

Spirax Sarco 25P Series Regulators are a popular main valve choice as they offer the ability to interchange or configure two or more pilots on the same regulator body—thus combining remote on/off control and pressure reduction. They use pressure pilots to provide accurate control of pressure in a choice of three pressure ranges and their corresponding color-coded springs (yellow, red, and blue). 

Depending on size and spring style, Spirax Sarco 25P Regulators can allow for pressure ratings anywhere from 125 PSI up to 300 PSIG and a maximum operating temperature of 450° to as high as 600° Fahrenheit. Temperature pilots can also be mounted along with these pressure pilots using an adapter bracket.

Cooney Brothers is proud to be an authorized distributor for Spirax Sarco and carry a large inventory of the 25P Pilot Operated Pressure Reducing Valves. They are available with Cast Iron, Steel, or Stainless Steel bodies and Stainless Steel internals that ensure excellent durability and corrosion resistance. These regulators are ½” to 4” in nominal size and they come in a wide range of screwed and flanged connection options. 

The Spirax Sarco 25P is a reliable, accurate regulator for reducing steam from high supply pressure to the most efficient operating pressure of the equipment, and it protects the equipment from dangerously high pressures. This capability allows these valves to be well-equipped for many applications where pressure reduction/control is the main concern.
