Combination Air Release Valve With SS304 Internal Parts For Fire Fighting Service
Features:
. Advanced design: Simple mechanism and strong float inside to prevent cracking during water hammer& quick close.
. 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 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 : BS EN 1092 and BS EN 558 and ANSI flange.
Triple Function:
1. Huge air release during filling of the pipeline
2. Small air release under pressurized pipeline
3. Huge air intake during draining of the pipeline
