 Main purposes: 
 The electric fluid knife gate valve is a mechanical, electrical, hydraulic, instrument integration, new automated knife gate valve, hydraulic cylinder, motor, fuel tank, fuel pumps, oil filters, hydraulic control valve combination percent. Control power to the piston rod displacement reciprocating motion to control the opening and closing of the valve, long-range, high altitude dangerous areas of concentration or process control, widely used in mine power plants, coal preparation, slag, food, building paper, pharmaceutical, chemical pipeline, connect or disconnect the line of grout, gold powder, iron ore, fiber, dust, chemicals, sewage treatment, asphalt exports and other media. 

 Main components of materials: 
 Body, covers carbon steel, stainless steel 
 Valve plate stainless steel 
 Stem stainless steel 
 Ring of rubber, PTFE, stainless steel, carbide 

 Two main performance specifications:
