TurboVent Air Admittance Valve with Combo Adapter & Tubular Waste Arm Extension

Sioux Chief 250 series TurboVent air admittance valves can be installed in either branch or stack applications as vent terminal for secondary venting within the plumbing system. The 250 series valve can connect to DWV system via a Schedule 40 adapter which complies with ASTM D2665 (PVC) or D2661 (ABS), or with a 1-1/2" tubular adapter. This valve will incorporate an actuating device which spins upon activation to keep the elastomeric sealing surface clean and free of debris. During drainage, actuating device should raise a designed distance under negative line pressure to allow optimal air flow into the DWV system. This valve provides a positive seal at 0 PSI and under any positive line pressure to prevent sewer gasses from entering the living space. Made in USA, compliant with IPC model code and certified to ASSE 1050 and 1051 standards.

Features:

• Actuating device within the unit spins with each activation, keeping the seal free of dust and debris
• Quick opening air valve at 0.01" negative pressure. Positive seal with 13 PSIG of back-pressure
• Protective debris cover
