Description

Fire Fighting System Combination Air Valve SS304/SS316 Internal Parts


Conbination Air Release Valve Fire Fighting For Clean Water​ Full Flow Area


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.
