CTV Type 11-SC3F Air Release Valve
The CTV Type 11-SC3F is a Single Chamber - Triple (3) Function Air Release Valve, available from DN50 to DN 300 in PN10, PN16 and PN25.
Type 11-SC3F Single Chamber-Triple Function air release valve provides 3 functions:
1. Large air release during filling of the pipeline.
2. Small air release under pressurized pipeline.
3. Large air intake during draining of the pipeline.
- Elegant design with simple mechanism, strong float to prevent cracking during sudden water hammer or quick closure.
- Aerokinetic mechanism to resist blow shut under higher air velocity even up to sonic velocity of air.
- No arms or levers to prevent vibrating, bending, direct closure of the float.
- Smooth cage outside of the float, keep float moving in specified guide rail.
- Bottom rubber buffer for collision prevention, and drain easy with proper holes around the cage during vacuum.
- Outside screen will be an option for safety and prevent insects or birds in.
