• 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, provide 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.
