G—GM-20/25 and GM-40/45 Series Dual-block Multi-function Gas Control Valves Technical Bulletin 3
Introduction
Figure 1: GM Series Dual-block Multi-function
The GM Series dual-block multi-function gas control valves are intended
for use on atmospheric and forced-draft gas burners in heating
installations. This multi-functional control on a dual-block valve body
provides a compact answer to gas train applications. The GM valve
replaces multiple gas train components, such as on/off gas valves, gas
pressure regulators, and modulating gas valves. Optional sizing of body
flanges offers greater adaptation to diversified burner designs and
applications. Valves are approved to European and North American gas
valve standards.
Typical applications include boilers, burners and ovens, rooftop units,
makeup air heaters, hot water heaters, kilns, and paint booths.
