Robertshaw 700-507 Gas Valve

The Robertshaw 700-507 Gas Valve is a professional-grade millivolt replacement valve designed for high-capacity applications up to 240,000 BTU. Engineering for heavy-duty performance, this 7000BMVR-S7C model features a slow-opening operator that ensures quiet ignition and stable burner engagement, a critical factor for furnace and boiler longevity. This combination valve integrates a manual gas cock, automatic pilot safety, and a millivolt operator into a single compact housing. It is calibrated for Natural Gas with a standard 3.5" W.C. regulation, though it can be field-converted for LP applications using the appropriate regulator cover plate. With a 1/2" NPT inlet and 3/4" straight-thru outlet, it accommodates diverse manifold configurations. The thermocouple and thermopile compatibility (250mV to 750mV) provides the flexibility technical contractors require for field servicing across various appliance brands.

• 240,000 BTU Capacity: High-output rating makes it suitable for large residential and light commercial furnaces.
• Slow-Opening Feature: Reduces ignition noise and provides soft starts for burner assemblies.
• Flexible Mounting: Multiposition design allows installation in any orientation except upside down.
• Standard Connection: Features 1/2" NPT inlet and 3/4" NPT outlet with an included 1" NPT reducer bushing.
• Pilot Safety: Independent automatic pilot safety valve ensures total gas shutoff if the pilot flame is lost.

Can I use this to replace a fast-opening valve?
Yes, the Robertshaw 700-507 is an ideal upgrade to prevent "booming" or hard ignitions in systems that originally used fast-opening valves, provided plumbing and electrical specs match.

Is this valve compatible with LP Gas?
The factory setting is for natural gas at 3.5" W.C., but it includes a regulator cover plate for LP conversion. Always verify manifold pressure with a manometer after conversion.

What electrical components are required for operation?
This is a self-powered millivolt valve typically used with a 750mV thermopile or a 250mV–750mV system, eliminating the need for an external 24V transformer.
