The plate radius of the knife gate valves slide gate has a bevelled cutting edge. As a result, solids can be cut through, achieving a tight seal in the closed position. On request, the thickness of the knife gate valves plate can be increased for higher operating pressures and/or higher quality material can be used.The slide plate's seat in the monoblock body is sealed tight by an elastomer seal in Body groove or metal to metal sealing.The standard material used for the knife gate valves elastomer seal is EPDM/ NBRor metal seatAlternatively, nitrile, viton, PTFE or else are available.The gland packing consists of several layers of braided fibre.An EPDM o-ring is additionally integrated into the layers of the knife gate valves gland packing as standard if request by customersTestingTesting includes a body shell test, a seat test and a cycling test to insure proper functioning of moving parts.Standard Shell test: Hydro test at 1.5 times the rated CWP (cold working pressure) Zero allowable leakageStandard Resilient Seat test: Hydro test at 15 psi (1 bar) and rated CWPMax. operating pressures for GAOCHUANG type PZ43 Knife Gate Valves:DN050-DN250: 10 barDN300-DN400: 6 barDN450: 5 barDN500-DN600: 4 barDN700-DN1200: 2 barMPaDNLDD1D2HN-MD0W(Kg)1.050431601251002854-M16180865461801451202984-M161801080461951601353154-M1622012100522151801553658-M1622014125562452101854008-M1623022150562802402104758-M2028029200603352952655408-M20360382506839035032063012-M20360663007844040036878012-M204001003507850046042888516-M2040011940010256551548299016-M22400195450114615565532110020-M22530285500127670620585120020-M22530389600154780725685145020-M27600529700165895840800170024-M276007908001901010950898200024-M30680850900203111010501005230028-M306809001000216122011601115250028-M3070010501200254145013801325280032-M3680013001.65043160125992854-M161808.565461851451202954-M1618010.780462001601353158-M1622013100522201801553658-M1622015125562502101854008-M1623023.5150562852402104758-M20280312006034029526554012-M2036040.72506840535531063012-M22360703007846041037578012-M224001073507852047043588516-M2240012940010258052548599016-M27400215450114640585545110020-M27530305500127715650609120020-M30530410600154840770720145020-M36600550700165910840788170024-M366008208001901025950898200024-M3668095090020311251050998230028-M3668010201000216125511701110250028-M4270011201200254148513901325280032-M488001480
