DP27, DP27E, DP27G, DP27GY,

DP27R and DP27Y Pilot Operated

Pressure Reducing Valves with SG Iron Bodies

Description

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.

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.

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.

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. Note: it is not available with a solenoid valve.

This can be remotely adjusted by varying a pressure signal to the pilot diaphragm. This is usually achieved

using a Spirax-Monnier pressure regulator and an instrument air supply.

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.
