Product Description GeneralFREE-VALVE Flanged Pneumatic Ceramic Rotary Double Disc Discharge Gate Valves are 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 double ceramic sealing faces of the valves are well ground and polished, which is ensure a reliable sealing performance of the valve.Features1. The valves are sturdy and maintenance free enough to withstand the most severe conditions.2.The sealing faces of the valve are made of toughened engineering ceramics with good abrasion resistance and prolonged service life.3.Product with customized structural length and connection size is available.4.The valve plate rotational motion of the valve disc can avoid the ash deposition on the sealing surface, so the valves have much longer service.5.The rotation structure with shorter stroke makes and the whole of ceramic sealing faces of the valves, which are ensure a reliable sealing performance of the valve.6.The ceramic gate is designed with double rotary disc ,two-side sealing can realized due to double disc structure of the Ceramic Rotary Double Disc Gate Valve.7.The valve body is equipped with a blow hole to prevent the body cavity from accumulating fly ash.Technical Specification 1Size RangeNPS2~NPS16,DN50~DN4002Nominal pressureNPS4~NPS12,DN100~DN3003Applicable Temperature0~200oC4Connection TypeFlange5DiscCarbon steel+ceramic,stainlees steel+ceramic6SeatCeramic7Pressure testGB/T13927, API5988Face to FaceGB/T12221, API6099OperatingPneumatic double acting cylinder Main dimensionsDNPNLDD1D2n-?dDN50PN10200160125994-?18DN65PN102201801451184-?18DN80PN102302001601328-?18DN100PN102502201801568-?18DN125PN102652502101868-?18DN150PN102802852402108-?22DN200PN103103402952668-?22DN250PN1040039535032012-?22DN300PN1045044040037012-?22Note:Face to Face dimension "L" can be customized according to customer requirements ApplicationFREE-VALVE Flanged Pneumatic Ceramic Rotary Double Disc Discharge Gate Valves are suitable for coal fired power plant, steel plant, cereals transport system, cement transport systems. In these applications, pneumatic conveying method is used to reduce manpower demand, and improve system efficiency and reliability, and is easy to realize automation.
