Oatey Sure-Vent Air Admission Valve

This valve’s sweet spot technology opens at -0.01 psi and seals at 0 psi and above, screening on air inlets to guard the seal. This one-way valve is designed to allow air to enter the plumbing drainage system when negative pressures develop in the piping system. This device shall close by gravity and seal the vent terminal at zero differential pressure (no flow conditions) and under positive internal pressures.

• Sweet Spot technology opens at -0.01 psi and seals at 0 psi and above, screening on air inlets to guard the seal
• For use as a secondary vent, one size approved to handle up to 3 in vent pipe
• Opens/closes as needed by building’s plumbing system, Complies to ASSE Standard 1050 and 1051
• Air admittance valve provide air to enter the plumbing drainage system without the use of a vent extended to open air and to prevent sewer gases from escaping
• One way valve designed to allow air to enter the plumbing drainage system when negative pressures develop in the piping system
• The device shall close by gravity and seal the vent terminal at zero differential pressure (no flow conditions) and under positive internal pressures
