1.The body is casted as whole,it is more relaxed to open,easier to replace the sealing ring,more convenient to maintain than slurry.
2.Back sealing is graphite or PTFE,the sealing is the best.
3.The polishing treatment on the gate surface can enhance the sealing and prolong life-span of packing and seat.
4.Products are widely used in paper making,sugar,mining,metallurgy,chemical industry,electric power,water treatment,etc.

Can offer all the type of actuators and manufactures,manual,electrical,peneumatic and pneumatic-hydraulic.
The pneumatic actuator of knife gate valve is usually straighe travel and double action,while installing set of handle,it clould open/close the valve by handle once the pneumaticis broken;it is extremely suitable for being applied fast open/close and frequent open/close.
It could realize the remote automatic control depends the working situation with the accessories included solenoid valve,air strainer and limited switch.
The electric actuator of knife gate valve is support the rotary actuator,conventional1380v voltage(220 v to be customized)The electric actuator is competewith handle,the handlecould open/close the valve once no power,It could effective control the medium to prevent the accident happening.
The Chainwheel actuator of knife gate valve is installed on the pipc in the air,It must keep the chain and sprocket parallel while operating,do not pull 90 degrees.
The bevel gear of knife gate valve is very easy to open/close.
Electric& Hydraulic Actuator
The electric&Hydraulic actuator of knife gate valve open/close through the reciprocating push.it come true far distance,high air and dangeranceor process control.The normal voltage is 380V,also could custom-made 220Vor 660V.
