Pneumatic gate valve has been widely utilized to control medium in petroleum, chemical, ocean shipping and other industries, for its reliable sealing and convenient maintenance.
Characteristics
1. The valve is equipped with pneumatic actuator.
2. Actuator of gate valve adopts double cylinder. Lift is increased by one time, compared with single cylinder pneumatic gate valve.
3. Avoiding the disadvantage of single cylinder gate valve that disc cannot be opened because of wedging inside body.
