1 1/4" VGD Double Gas Valve

The normally closed VGD series of modular double-body gas valves combine with SKP series electro-hydraulic actuators to provide safety shut-off, gas pressure regulation and/or air-gas ratio control for commercial or industrial gas burners.

• UL listed, FM approved, CSA certified, IRI approvable, ISO 9001 and 14000 certified.   CE, Australian approved versions available
• ¼“‐inch NPT pressure taps on the inlet and outlet and between main valves (see Table 2 for details)
• Stainless steel mesh inlet filter protects the valve seat(s) as well as downstream components
• Dual stem guides ensure precise disc alignment and tight shut‐off
• Valves in connection with SKPxx.xxxU actuators open slowly and close rapidly
• Compact VGD20.xxxU double‐valve bodies consist of 2 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 (SKP2x.xxxU, SKP5x.xxxU, SKP7x.xxxU)
• A 1‐inch NPT vent connection between the valves
• Each VGD20.xxxU double‐valve requires 2 threaded mounting flanges(AGFxx.xxU). Each flange includesthe necessary installation hardware (bolts, nuts and O‐ring). Each mounting flange has a ¼â€inch NPT pressure tap. The flanges can be pre‐mounted onto the pipe, and then bolted onto the VGD20.xxxU 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
• Connecting pattern of the 1...2 inch AGFxx.xxU flanges are identical. This space permits any AGFxx.xxU flange to be mounted to any VGD20.xxxU valve body
