Series CR-101-HP High Pressure Air Vent and Vacuum Relief Valve

SERIES CR-101-HP ALUMINUM BODY CONTINUOUS ACTING HIGH PRESSURE AIR VENT AND VACUUM RELIEF VALVE is a higher-pressure air vent for areas with extreme elevations and where extra protection is required. It has a high-strength, corrosion-resistant aluminum alloy body, baffle, and hard anodized aluminum poppet, and a specially-designed cylindrical float. The guide rod and assembly are stainless steel. Cast iron is used for the threaded base to provide easy installation and removal without the thread damage that can occur with aluminum threads.

The 2″, 3″, and 4″ models are rated to 300 psi, and laboratory tested to 750 psi. The continuous acting mechanism seals at pressures as low as 2 psi, providing the best published performance in the industry.
