Model 5885 has three separate valves that address pressure / vacuum conditions in underground storage tanks (UST). • The Husky 5885 pressure / vacuum (PN) vent incorporates three separate valves to control over -pressure and vacuum conditions that arise in storage tanks. This three valve system provides the necessary protection and durability needed in a UST vent cap. • The 5885 has an internal screen to protect the pressure plate in the event of a bad bulk drop. ■ The vacuum valve is diaphragm operated and provides 10 times more sealing force than gravity devices. It consistantly opens at 6" - 10" of water column (WC) vacuum. • HUSKY PRESSURE / VACUUM VENT • The first over -pressure valve is diaphragm operated, giving 10 times more sealing force than gravity devices. It opens at 2.5" - 6" WC pressure. • The safety over -pressure valve is designed to handle high pressure / high flow conditions. This valve will vent up to 7900 SCFH at 2 PSI. • Certified to less than 1/3 of the new CARB EVR Standard CP -201 which allows installation of 3 P/V vents maximum. This reduces installation time by not having to manifold the vent pipes together. • The 5885 is a threaded vent cap that is easily installed by using the cast -on hex nut. This also allows tightening without having to go between vent pipes.
