Gas Valve for Furnaces and Pools
This Robertshaw 700-506 gas valve serves natural-gas furnaces and swimming-pool heaters with a straight-through flow design. It operates on a 750 mV standing-pilot system and includes an integrated pressure regulator with an outlet pressure tap for precise adjustment.
Upgrading from Worn or Mismatched Valves
The valve replaces failed or incorrectly sized units in existing 200,000 BtuH heating systems. The jump is worth it when the original valve leaks, fails to hold pilot voltage, or cannot deliver the required 3.5 in wc manifold pressure for reliable burner ignition.
Capacity and Headroom
The valve comfortably handles heating loads up to 200,000 BtuH on natural gas or liquid propane using the supplied conversion kit. It runs out of headroom above that rating, so larger commercial boilers or multi-zone installations will require a higher-capacity valve.

Questions about this item
What size outlet pressure tap does the 700-506 gas valve include?
The Robertshaw 700-506 includes a pressure tap on the outlet side for checking the 3.5 in wc manifold pressure during setup.
How do you wire the 750 mV pilot circuit on this Robertshaw valve, and what step is often missed?
Connect the thermocouple leads to the screw/spade terminals marked for the pilot circuit; the step often missed is verifying the generator produces a full 750 mV before turning the knob to On.
When should the pressure regulator on the 700-506 be checked or replaced?
Inspect the built-in regulator if manifold pressure drifts from 3.5 in wc or after any exposure to debris; replace the valve if regulation cannot be restored.
