SS316 Internals Triple Function Full Flow Area Single Chamber Sewage Combination Air Release Valve
Features:
. Spilling free is an outstanding feature.
. Advanced design: Simple mechanism and strong float to prevent cracking during sudden water hammer& quick closure.
. Wider middle body, shorter in height.
. Slow down the flow velocity, keep sewage in the body.
. Drain boss at the top & bottom for cleaning.
. Float movement support by both cage and body guide
. Fast water rising on the back of middle part, prevent direct flushing up to top and out of main body.
. No arms or levers to prevent vibrating, bending, direct closure of the float.
. Fully fusion epoxy coated inside and outside of valve body for long term services.
. Manufacturing standard : BS EN1074-4, AWWA C512
. Flange drilling and dimension : BS EN 1092 and BS EN 558 and ANSI flange.
• 100% -full flow area thru the valve internal.
• Can blow off the water on top of the sealing arc thru small orifice and keep it dry to prevent polluted water coming into pipeline during vacuum.
• Most parts of valves can be recycled.
• All internal parts are 316SS material without rusting.
• Float with a rubber sealing on top providing better sealing ( larger buoyancy ) effect on small orifice.
• Float with a rubber sealing can be as an absorber to prohibit water hammer direct acting on the sealing arc and seat impact.
