Spirax Sarco Pressure Reducing Valve DP27
Spirax Sarco Pressure Reducing Valve DP27 A pilot operated pressure reducing valve for steam or compressed air applications.Only one control spring for down stream pressure range 0.2 bar g to 17 bar g.
Externally accessible pilot filter to protect the pilot valve from pipeline dirt.
All DP27, DP27E, DP27G, DP27GY, DP27R and DP27Y pilot operated pressure reducing valves have bodies manufactured using SG iron.
These products are not suitable for oxygen service.
DP27 Suitable for steam or compressed air applications.
DP27E Suitable for steam applications. It incorporates an electrical solenoid valve in the pipe assembly allowing remote closure by means of a switching or timer device.
DP27G Suitable for compressed air and inert industrial gas applications. Its design incorporates a nitrile soft seal pilot and main valve. Note: it is not available with a solenoid valve.
DP27GY Suitable for compressed air, inert industrial gas and critical low-pressure control applications. Its design incorporates a nitrile soft seal pilot and main valve, and uses a lower rate control spring with a downstream pressure range of 0.2 - 3.0 bar.
DP27R This can be remotely adjusted by varying a pressure signal to the pilot diaphragm. This is usually achieved using a pressure regulator and an instrument air supply. DP27Y Suitable for steriliser or critical low -pressure control applications. It uses a lower rate control spring with a downstream pressure range of 0.2 - 3.0 bar.
