Robertshaw 700-503 Gas Valve

The Robertshaw 700-503 is a combination gas valve designed for furnace applications with a straight-thru flow direction. It supports liquid propane, liquid propane/air mixtures and natural gas. The unit handles a maximum heating capacity of 240000 BtuH and operates between -40 and 175 degrees F. A mechanical thermostat is included while a pressure regulator is not included.

Suits furnace installs needing straight-thru flow

This valve suits installers fitting furnaces that require a straight-thru port configuration and a heating capacity up to 240000 BtuH. It works with the three listed gas media and includes a mechanical thermostat for direct control. Buyers who need a built-in pressure regulator or a different port orientation should look at alternative models.

Mechanical thermostat included.

The bundled mechanical thermostat allows immediate temperature control without a separate purchase. The absence of a pressure regulator means you must supply and install one separately to meet system requirements. Pilot port connection is 1/4 in and main ports accept 1/2 in and 3/4 in sizes.
