Bevel Equipment stainless steel JIS Flange CZPT Knife Edge Gate Valve

The knife gate valve is a uni-directional wafer valve for general industrial software.
The nominal diameter CZPT selection from DN50 to DN600 with flange connections complying with EN 1092-one PN10/PN16 or alternatively, ANSI B16.5,MSS SP eighty one
The knife gate valve is predominantly utilised in the paper and pulp, chemical, and mining industries, and the meals business as well as sewage treatment method crops, and in the sugar, metal and animal feed sectors.
Push actuators provided for the knife gate valve include handwheel with growing or non-rising stem, or alternatively double-or one-performing pneumatic cylinders (spring return), Bevel Gear, chain equipment and electric actuators.
The framework of the uni-directional knife gate valves is a wafer design forged monoblock entire body, with elevated experience and strengthened ribs for bigger nominal diameters for added physique strength.
The monoblock human 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 steel 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 reduce through, attaining a restricted seal in the shut placement. On request, the thickness of the knife gate valves plate can be enhanced for increased operating pressures and/or increased quality substance can be used.  
The slide plate’s seat in the monoblock physique is sealed limited by an elastomer seal in Physique groove or Metallic to metallic sealing
The standard substance used 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 a number of levels of braided fibre.
An EPDM o-ring is moreover integrated into the layers of the knife gate valves gland packing as standard if request by consumers
 
Tests
Testing involves a human body shell test, a seat check and a biking test to insure proper operating of transferring parts.
CZPT Shell test: Hydro examination at 1.5 occasions the rated CWP (chilly doing work force) Zero allowable leakage
CZPT Resilient Seat take a look at: Hydro examination at fifteen psi (one bar) and rated CWP
