Product Descriptio 

I Summary 

Knife gate valve design is based on the growing needs of the industry that closed performance and flow regulation performance of the valve is reliable. Its high functionality,simple maintainability and excellent flow characteristics is suitable for fluid and dry media.

II  Pneumatic movable sealing regulate knife gate valve 

ZC Knife gate valve can be used as oil storage stations oil level regulating,shut-off valve,slurry tank discharge valve,and kitchenware coating applications,Etc.
This kind valve is designed to withstand the high differential pressure and full Bore,difficult to plug, easy to operate.

ZF Knife gate valve is a kind of valve which is used for slag discharge processor,coarse slag filter and desander,This valve has a circular import and a square export to prevent the valve plug.Standard products,ZF Knife gate valve provide whole quenching treatment flash board.This valve can provide a adapter connector at the export, its easy to transit to circular flange. ZF Knife gate valve is the valve for extreme operating conditions.

ZA Knife gate valve is unidirectional sealing valve, especially suitable for high concentration pulp and other working conditions of risk of clogging. Insert type knife gate valve ensure that the valve can close in the solid granules medium.Commonly used medium is pulp, corrosive liquid,waste and garbage.

Common valve material

1IRON

 Good strength and corrosion resistance

·Cast Iron：GG25，ASTM A126

·Ductile Iron：GGG40，GGG40.3，GGG50，ASTM A 395        

  

2STEEL

·Carbon steel：

·Cast steel corresponding to the material label：ASTM A216 WCB，DIN 17 245 –    1.0619，AFNOR A48 C – M，BS1504-16，JIS SCPH 2。  

·The corresponding material label of forged steel：ASTM A105(A105N)

·LCBLow carbon steel，WC6 and WC9 High temperature carbon steel

· Stainless Steel

·304/CF8stainless steel：The corrosion resistance is worse than 316. The typical temperature range is -200 c to 800 c

·Cast steel corresponding to the standard number：ASTM A351 CF8，AISI 304，DIN 10213-4 – 1.4308

·Standard number for forged steel：ASTM A 182-F304，1.4301 

·304L/CF3stainless steel：304L stainless steel is a low carbon type of 304,with improved welding performance

·Cast steel corresponding to the standard number：ASTM A351 CF3，AISI 304L，DIN 17440 – 1.4306

·Standard number for forged steel：ASTM A 182-F304L DIN 1.4452

·316/CF8Mstainless steel：316 stainless steel is often used in corrosive media, such as organic or inorganic acids, but it can not.For hydrochloric acid, sulfuric acid and phosphoric acid. Its corrosion resistance is better than 304. Because of the presence of molybdenum, the creep resistance at elevated temperature has been greatly improved. Typical temperature ranges from -253 to 815 C.

·Cast steel corresponding to the standard number：ASTM A351 CF8M，AISI 316，DIN 17445 – 1.4408，AFNOR，Z6CND18.10.3M，BS 1505 – 316C15，JIS SCS 14 A

·Standard number for forged steel：ASTM A 182-F316，A240gr，F316，AISI316，DIN 17 440-1.4401

·316L/CF3Mstainless steel：316L stainless steel is 316 carbon steel with low carbon and welding performance is improved.The corrosion resistance under temperature is higher than that of 316, and the applied temperature is similar to that of 316, the highest temperature is 455 degrees.

·Cast steel corresponding to the standard number：ASTM A351 CF3M，AISI 316L，DIN 17440 – 1.4404，AFNORZ2CND18.12.3M，BS 1504 – 316 C12，JIS SCS 16A

·Standard number for forged steel：ASTM A 182-F316L DIN 17122 1.4404，18-14-3 1.4435
