Hydroheat Supplies offer the Apollo range of reduced pressure zone back flow prevention valves and dual check valves.
Designed to provide maximum protection against back-siphonage or backpressure from substances that are hazardous to the potable water supply. The top accessed modular check valve cartridges provide captured springs, replaceable seats, and reversible silicone seat discs. This Made in America assembly features ball valves with stainless steel handles and trim as standard.
A low hazard device that prevents backflow by either backpressure or back-siphonage resulting from a cross-connection between potable water lines and substances that are objectionable, but not health-hazards.
