For a valve of the non Rising Stem type, there is no upward stem movement if the valve is opened. The stem is threaded into the disk. As the handwheel on the stem is rotated, the disk travels up or down the stem on the threads while the stem remains vertically stationary.

DN 50-400 BI- Direction Tightness Pneamatic Knife Gate Valve

Characteristics of pneumatic knife gate valve:
1. Adopting a clip on structure, it has a small volume, light weight, low flow resistance, and easy installation and maintenance.
A fully open channel can prevent the medium from depositing inside the valve.
The newly developed U-shaped sealing ring ensures good sealing of the valve.
4. The external sealing of the pressure head is achieved through a sealing strip embedded in the valve body, which can be adjusted by screws and pressure plates.
Pneumatic knife gate valve pneumatic device parameters and characteristics:
Pneumatic knife gate valve is a relatively complex automatic control instrument composed of various pneumatic components and valve bodies. It is typically used in applications that require quick cutting or opening.
1. Dual action: Dual position control, used for opening and closing valves;
2. Single action: (spring reset): When the equipment and air circuit are cut off or fail, the valve will automatically open or close.
Optional accessories:
1. Single control or dual control solenoid valve (24V, 220V and other voltages are available for selection, and explosion-proof solenoid valve can be optionally selected if necessary).
2. Proximity switch
3. Air source treatment triple joint (including pressure reducing valve, filter, oil mist device).
4. Electric/gas valve positioner (for regulating type).
