chain wheel lugged Knife Gate Valve

The Lug knife gate valve is a uni-directional wafer valve for common industrial application.
The nominal diameter CZPT range from DN50 to DN600 with Lugged flange connections complying with EN 1092-one PN10/PN16 or alternatively, ANSI B16.5.
The knife gate valve is predominantly utilised in the paper and pulp, chemical, and mining industries, andthe foodstuff sector as well as sewage remedy vegetation, and in the sugar, metal and animal feed sectors.
Generate actuators offered for the knife gate valve incorporate handwheel with rising or non-climbing stem, or alternatively double-or single-acting pneumatic cylinders (spring return), Bevel Gear, chain equipment and electric powered actuators.
The framework of the uni-directional knife gate valves is a wafer fashion forged monoblock human body, with lifted encounter and bolstered ribs for greater nominal diameters for further physique toughness.
The monoblock body of the knife gate valves is CZPT in both WCB or alternatively in stainless metal CF8M/CF8/CF3/CF3M.
The slide plate of the knife gate valves is making use of stainless metal AISI 304,201,301,304L, 316L or AISI 316 or else. The plate radius of the knife gate valves slide gate has a bevelled cutting edge. As a consequence, solids can be cut by way of, achieving a restricted seal in the shut place. On ask for, the thickness of the knife gate valves plate can be improved for higher running pressures and/or increased high quality substance can be used.
The slide plate’s seat in the monoblock body is sealed tight by an elastomer seal in Body groove or Steel to metallic sealing.
The regular substance employed for the knife gate valves elastomer seal is EPDM/ NBRor Steel seat
Alternatively, nitrile, viton, PTFE or else are CZPT.
The gland packing is made up of numerous layers of braided fibre.

An EPDM o-ring is furthermore built-in into the layers of the knife gate valves gland packing as common if ask for by clients

Testing
Tests involves a human body shell take a look at, a seat take a look at and a biking examination to insure proper performing of shifting components.
CZPT Shell take a look at: Hydro test at one.5 instances the rated CWP (cold working force) Zero allowable leakage
CZPT Resilient Seat examination: Hydro check at fifteen psi (one bar) and rated CWP

Max. running pressures for GAOCHUANG type PZ43 Knife Gate Valves:
DN050-DN250: 10 bar
DN300-DN400: six bar
DN450: five bar
DN500-DN600: 4 bar
DN700-DN1200: two bar
