G—UL Listed GS-20/25 and GS-40/45 Series Single-block Multi-function Gas Control Valves Technical Bulletin 3
Introduction
Figure 1: UL Listed GS Series Single-block
Multi-function Control Valves
The UL Listed GS Series single-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 single-block valve body
provides a compact answer to gas train applications. The GS 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 North American and European gas
valve standards, including UL 429.
Typical applications include boilers, burners and ovens, rooftop units,
makeup air heaters, hot water heaters, kilns, and paint booths.
