VGD40 Series is offered in pipe sizes from 1.5 to 6". The gas valve contains a double-seated design to provide high flow rates. A 4" valve assembly incorporating the control functions of a strainer, regulator and two safety shut-off valves is less than 14" long. Ports allow the mounting of high and low gas-pressure switches, vent valves or gas-valve leak-testing control all on one block. The double valve can be fitted with the company's actuator so that one compact unit provides the functions of the main gas regulator, safety shut-off valve, air-gas ratio regulator and mixing tube.
