New safety valve for opening pressures less than 0.5 bar

Production of sophisticated hydroformed components

Salzgitter Hydroforming (SZHF) is a specialist in the series production and development of hydroformed components. This unique technology enables the production of sophisticated com-

The AV619 safety relief valve from Witt Gas Techniques Ltd, UK, 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. Supplied with a TÜV pressure-setting certificate, this new safety valve provides a sensitive opening pressure from 5 mbar up to 500 mbar. A high relieving capacity is also possible due to the large cross section of the valve opening. It is also able to work in a temperature range of -40°C to approximately +300°C. This new safety relief valve, which can be used with all technical gases, is an addition to the existing range of relief valves available from Witt Gas Techniques. It 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. Depending on the connection, the flow capacity can range from 2.6m 3 /hr to 90.7m 3 / hr, whilst the setting pressure p e ranges from 5-500 mbar. The valve seat seal material is dependent on the gas being used and specified at the point of order. These valves are compact in size for easy installation and every valve is 100 per cent tested by Witt Gas Techniques before leaving the factory. Witt Gas Techniques Ltd – UK Fax : +44 1925 230055

ponents. The main advantages are the low weight, high rigidity of the parts and the possibility to avoid joining operations. All of these properties con- tribute to a cost-effective lightweight construction. The company uses the most modern production equipment and one of the largest machine facilities in this industry sector to manu- facture components
