Product Specifications

Phase One EVR approved pressure/vacuum vent valve.

• Three precision valve assemblies are at the core of our vent valve design.
• The first overpressure valve is diaphragm operated giving 10 times more sealing force than gravity devices.
• It consistently opens at 2.5-6” of water column (WC) pressure.
• The safety overpressure valve is designed to handle high pressure/ high flow conditions. This valve will vent at a rate of 7900 SCFH @ 2 psi.
• The vacuum valve is also diaphragm operated and provides 10 times more sealing force than gravity devices.
• It consistently opens at 6”-10” of water (WC) vacuum.
• An internal wire mesh screen is incorporated into the design of the 5885 vent valve to protect the pressure plate in the event of an improper bulk drop.

The Husky 5885 is the only CARB approved Phase One EVR vent valve available for use in California. The valve is identified with yellow colored labels one of which boldly identifies the vent valve as EVR approved.
