Knife Gate Valve Normal Features  Sizes:DN 50~600mm  NPS 2"-24" Body Material:WCB/CF8/CF8M/CF3/CF3M Gate: 2Cr13/ 304/304L/316/316L Sealing Material: NBR:90°C    EPDM: 120°C Viton: 200°C PTFE: 200°C Metal seal :304/316+Satellite Design Standard: MSS SP81 Max Working pressure: DN50~DN250:10Bar NPS2~NPS10:150Psi DN300~DN450: 7Bar  NPS12~NPS18:90Psi DN500~DN600: 4Bar  NPS20~NPS24: 60Psi  Working Temperature:  -29°C ~120°C  Standard flange connection:   The series knife gate valve is a normal uni-directional knife gate valve which shutoff medium directly.The beveled knife-like edge cuts through fibers and solid particles in the flow stream.  Body:  l   Integral body structure design,small flow resistance,easy assembly,minimize the possibility of shell leakage.  l   Fixed guide claw,no groove design,the solid would not be accumulated and stuck.  Gate:  l   The slide gate has a bevelled cutting edge. As a result, solids can be cut through, achieving a tight seal in the closed position.  l   On request, the thickness of the knife gate valves gate can be increased for higher operating pressures and/or higher quality material can be used.   Seat:  l   Side entry and replaceable seat design,can be changed freely.  l   Theseat ring retainer avoid flow fluid flushing the seat ring.  l   Material of seat is selected according to the meduim and service convice condition,choosing metal seal or soft seal.Metal seal is 304+stl or 316+stl.Soft seats are PTFE,EPDM,NBR,which have good sealing performance.  Test:  l   Body test: Working pressurex1.5  l   Seat test: Working pressurex1.1  Application:  knife gate valve is widely used in the industry application such as Pulp and Paper,Power plants,Wastewater treatment plants,Chemical plants,Iron and Steel Industry,Food and Beverage,Bulk handling,Mining,etc.   Brake Valves,Cnc Machined Housing,Maxi Air Brake Valve,Iron Casting For Low Pressure Ningbo CCMS Industrial Co.
