The VGD gas valves from Siemens make full use of the advantages offered by the double valve design: Compact and low weight. They afford high inlet pressures of up to 100 KPa and excel in high flow rates. Any valve of the VGD line can be combined with any of our actuators. And since we also attach great importance to versatile accessories, the universal mounting plate enables any valve of the VGD40 line to be equipped with pressure switches and valve proving systems of all major suppliers. The mounting plates are interchangeable, allowing them to be matched to gas trains arranged on the left or right hand side. The VRD40 variant was specifically designed and developed for use with alternative types of gas, such as recycling gas.
Technology for more safety
Safety is of prime importance when it comes to gas applications. While VGD20 are of single-seat design, all double valves of the VGD40 line use a unique, patented double-seat design. This special design ensures that both valve seats are closed by two individual prings producing independent forces of more than 100 N. The resultant automatic compensation of distance offers more safety.
