FREE-VALVE Brand Pneumatic Swing Disc Fly Ash Discharge Valve is designed for pressurized and vacuum systems including dense and dilute phase pneumatic conveying systems, discharge and vent applications in steel plant and coal power. The whole of ceramic sealing faces of the valves are well ground and polished, which is ensure a reliable sealing performance of the valve.
Features
1.The cylinder piston rod does not contact with the medium directly, which greatly prolongs the service life of the cylinder and has a higher service temperature without damaging the cylinder.
2.The sealing faces of the valve are made toughened tungsten carbide with good abrasion resistance and prolonged service life.
3.Product with customized structural length and connection size is available.
4.The valve disc rotational motion can avoid the ash deposition on the sealing surface during opening and closing, so the valves have much longer service.
5.Higher temperature can be installed on site .
