The newly released AV619 safety relief valve from Witt Gas Techniques Ltd, the Warrington based gas safety, control, mixing and analysis equipment supplier, is a new spring loaded, direct acting safety relief valve for venting excess gas pressure from receivers, pipelines and other equipment used in the chemical and oil processing industries.

Features of the new safety valve include a sensitive opening pressure from 5 mbar up to 500 mbar, a high relieving capacity due to the large cross section of the valve opening and the capability to work in a temperature range of -40°C to approximately 300°C.

An addition to the existing range of relief valves available from Witt Gas Techniques, the company’s new product is available in either brass or stainless steel and has a range of inlet and outlet connections to suit. An adaptor is also available for connection to a ventilation pipe.

The valve seat seal material is dependent on the gas being used and specified at the point of order., while the valves are compact in size for easy installation and every unit is 100% tested by Witt Gas Techniques before leaving the factory.
