White PVC Shut-off Valve for air ducts
PVC Shut-off or Non-Return Valve for Ventilation, Ducts, Pipes, and Extraction Ventilation Systems. The non-return valve blocks the passage of air through ducts, extraction pipes, etc., when the extraction system is turned off. The PVC shut-off valve is also called a "butterfly" valve; it is a valve where the shutter is a disc that rotates around an axis perpendicular to that of the pipe, obstructing the passage, and is operated by a "spring-loaded" mechanical return system. Assembly is simple, fast, and secure. It prevents the escape of odors when the extraction system is not in operation. Available sizes:- Ø100mm non-return valve.
- Ø125mm non-return valve.
- Ø150mm non-return valve.
