Hayward DIRECTIONAL VENT VALVE W/O-RIN

The Hayward Directional Vent Valve with O-Ring is a specialized manual air relief component designed for use on the top of filter tanks to facilitate the safe release of trapped air from the pressurized vessel. Manufactured from a durable, UV-stabilized and chemical-resistant polymer, this valve features a directional nozzle that allows the operator to control the path of the water spray during the venting process, keeping the equipment pad dry. Its primary mechanical function is to bleed air from the system during pump startup and to provide a manual vacuum break when draining the tank for maintenance or cartridge cleaning. The integrated O-ring provides a precise, airtight seal at the base of the valve, preventing accidental leaks and maintaining the internal hydraulic pressure necessary for efficient filtration. This assembly is engineered to withstand the constant pressure fluctuations and the corrosive effects of salt-chlorine environments without becoming brittle or seizing. For shipping and logistical purposes, the estimated weight of the Hayward Directional Vent Valve with O-Ring is approximately 0.32 pounds in its retail protective packaging, while the actual dry weight of the valve and rubber seal is roughly 0.18 pounds.
