Material: Cast iron air vent valves are typically made from high-quality cast iron to ensure durability and resistance to corrosion.
Size: Available in various sizes to suit different pipe diameters and system requirements.
Pressure Rating: Designed to withstand specific pressure ranges typical of plumbing systems.
Temperature Rating: Suitable for operating temperatures commonly encountered in plumbing applications.
Connection Type: Threaded or flanged connections for easy installation and compatibility with existing plumbing systems.
Operation: Manual or automatic operation, depending on the design and application requirements.
Classification:
Based on Operation:
Manual Air Vent Valves: These valves require manual intervention, typically operated by a screw or lever mechanism to release trapped air.
Automatic Air Vent Valves: Equipped with a float mechanism or other automatic mechanisms to release air as it accumulates in the system without manual intervention.
Based on Design:
Float Type: Uses a float mechanism that rises with the accumulated air, triggering the valve to open and release the air.
Disc Type: Utilizes a disc or diaphragm that opens and closes based on air pressure differentials, allowing air to escape when necessary.
Spring-loaded Type: Employs a spring-loaded mechanism that opens the valve under certain pressure conditions to release air.
Based on Application:
Residential: Designed for use in residential plumbing systems, typically smaller in size and simpler in design.
Commercial/Industrial: Built to withstand higher pressures and volumes of air, suitable for larger-scale plumbing systems in commercial or industrial settings.
