Full Flow Area Conbination Air Release Valve , Fire Fighting For Clean Water
Triple Function:
1. Large air release during filling of the pipeline
2. Large air intake during draining of the pipeline
3. Small air release under pressurized pipeline
Features:
. Advanced design: Strong float and simple mechanism can prevent cracking during sudden water hammer& quick closure.
. No arms or levers that can prevent vibrating, bending, direct closure of the fl oat.
. Smooth cage outside of the float, keep float moving in specifi ed guide rail.
. Bottom rubber buffer for collision prevention, and drain easy with proper holes around the cage during vacuum.
. Outside screen is for safety and prevent insects in.
. Fully fusion epoxy coated inside and outside of valve body for long term services.
. Flange drilling and dimension comply with : BS EN 1092 and BS EN 558 and ANSI flange.
