The pneumatic knife gate valve is a relatively complex automatic control instrument, consisting of various pneumatic components and a valve body. It is commonly used in applications requiring rapid shutoff or opening. Double-acting: two-position control of valve opening and closing; Single-acting (spring return): the valve automatically opens or closes in the event of electrical and pneumatic circuit shutoff or failure.
