Grand Canyon 710-502 Standard Millivolt Gas Valve - NG

The Grand Canyon 710-502 Standard Millivolt Gas Valve (NG) is the natural-gas millivolt control valve used across many Grand Canyon vented burner systems. Designed for dependable manual and remote-capable operation, this valve regulates gas flow through a standing-pilot millivolt circuit and pairs with compatible millivolt pilot assemblies and remote systems.

Because it uses a self-powered millivolt generator, the 710-502 operates without external electricity—providing reliable performance even during power interruptions. This valve is listed under Grand Canyon’s replacement parts catalog and is intended for use only with GCGL burners and compatible ignition components.
