Hoke Gyrolok compression tube fittings have been selected by Birkett for the latest models in its range of pilot-operated safety and thermal relief valves to ensure the highest available standards of quality and reliability.
Factors contributing to the choice of Hoke were the unique features of the Gyrolok fitting including its controlled ferrule drive to improve remake life, a butt-seal to provide secondary seal and the Gyrogage which ensures proper fitting make-up.
The Birkett Safeset pilot-operated valve is available in a variety of sizes from 1in x 2in to 8in x 10 in. Pressure ratings up to 450 bar and temperature ranges of -40°C to +260°C are also available.
Birkett has been providing relief valves for use in the process, petrochemical and oil & gas industries for more than 100 years. A policy of continuous improvement ensures that Birkett valves will always meet current legislative requirements including ISO 9001, ISO 4126, ASME VIII, TUV, NACE and DNV.
