3" 100 psi AV-150 Series Air/Vacuum Relief Valve | WTRAV1503

Key Features

• The Model AV-150 uses a semi hard, precision ground, inert solid plastic float ball
• The float seats against a precision "O-ring" providing a tight seal at very low pressures where other vents often leak
• They have excellent seating characteristics and operate trouble-free at pressures up 100 psi on the 3 in. units
• The aerodynamic "air flow" design of a high strength alloy aluminum body and full baffle assures maximum vent capacity without premature closing
