Chain Wheel Flange Industrial Knife Gate Valve

Chain wheel Flange Knife Gate Valve

The knife gate valve is a uni-directional wafer valve for general industrial software.
The nominal diameter CZPT range from DN50 to DN600 with flange connections complying with EN 1092-one PN10/PN16 or alternatively, ANSI B16.five,MSS SP 81
The knife gate valve is predominantly utilised in the paper and pulp, chemical, and mining industries, and the foods sector as well as sewage remedy crops, and in the sugar, metal and animal feed sectors.
Travel actuators offered for the knife gate valve consist of handwheel with increasing or non-rising stem, or alternatively double-or solitary-acting pneumatic cylinders (spring return), Bevel Gear, chain gear and electrical actuators.
The composition of the uni-directional knife gate valves is a wafer style forged monoblock body, with raised confront and strengthened ribs for more substantial nominal diameters for extra human body energy.
The monoblock body of the knife gate valves is CZPT in possibly WCB or alternatively in stainless metal CF8M/CF8/CF3/CF3M.
The slide plate of the knife gate valves is using 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 chopping edge. As a consequence, solids can be reduce by way of, obtaining a limited seal in the shut position. On ask for, the thickness of the knife gate valves plate can be elevated for higher working pressures and/or higher top quality substance can be used.  
The slide plate’s seat in the monoblock physique is sealed limited by an elastomer seal in Body groove or Metallic to steel sealing
The normal substance utilized for the knife gate valves elastomer seal is EPDM/ NBR or Steel seat
Alternatively, nitrile, viton, PTFE or else are CZPT.
The gland packing is made up of many levels of braided fibre.
An EPDM o-ring is furthermore integrated into the levels of the knife gate valves gland packing as common if ask for by customers
 
Tests
Tests includes a body shell test, a seat test and a biking test to insure suitable operating of relocating areas.
CZPT Shell test: Hydro check at one.five moments the rated CWP (chilly functioning force) Zero allowable leakage
CZPT Resilient Seat test: Hydro check at 15 psi (one bar) and rated CWP
