Available types

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.
