VGD20.403U Siemens Combustion 1 1/2" GAS VALVE DOUBLE | Midwest Appliance Parts

NEW Siemens VGD20.403U 1-1/2" Double Gas Valve 1" The normally closed VG Series of modular single and double-body gas valves combined with SKP Series electro-hydraulic actuators provide safety shut-off, gas pressure regulation and air/gas ratio control for commercial and industrial gas burner. Features: Compact VGD20 double-valve bodies consist of two safety shut-off valves in series. The first (inlet) valve has a flat valve disc applicable for safety shut-off function only. The second (outlet) valve has a contoured valve disc for use with pressure regulating actuators. A one-inch NPT vent connection between the valves. Each VGD20 double-valve requires two threaded mounting flanges (AGAxxU). Each flange includes the necessary installation hardware (bolts, nuts and O-ring). Each mounting flange has a 1/4-inch NPT pressure tap. The flanges can be pre-mounted onto the pipe, and then bolted onto the VGD20 gas valve body. This feature eliminates the use of pipe unions and permits the gas valve assembly to be easily removed from a gas train. The overall dimensions of both the 1-1/2-inch and 2-inch AGAxxU flanges are identical. This permits a 1-1/2-inch flange to be mounted on a 2-inch valve body or vice versa
