Pneumatic Lug/Pnentration Type Knife Gate Valve
Summary:
Pneumatic knife gate valve is composed of stainless steel clamp knife gate valve and pneumatic actuator. The bottom of the gate is a knift-type oblique cut, with good shear effect, so that the valve is closed without media blocking, and can scrape the adhesion on the sealing surface, automatic removal of debris. It is most suitable for fluids that are difficult to control, such as slurry, powder particles, fibers, etc. PZ673H strikes with pneumatic knife gate valve pressure ranges generally use within 1.0 MPa, the temperature is below 120 ° C. High temperature can be replaced by special materials. It is widely used in papermaking, petrochemical, mining, drainage, food and other industries. It has a variety of seats to choose from, and can be based on the field control requirements, equipped with electric or pneumatic actuator, valve automation.

Advantages:
1. It adopts double-clamped structure, and has small volume, heavy reclamation and light weight. It has fully open channels to prevent media deposition in the valve.
2. In the process of opening and closing, the gate and sealing surface are specially designed with less friction and durability.
3. The upper seal adopts the upper cover structure. So that the upper seal is changed from a large area of rectangular seal to a small area of circular seal, and the sealing performance is greatly improved.
4. After the sealing device is installed on the top of the handwheel, all the moving parts of the valve can be closed, and the screw drive of the gate and stem will not get stuck due to dry lubrication.
5. The gate plate has the function of knife gate, which can effectively deal with all kinds of sundries in the new brake medium.

Principle:                                                                                                                                      
Pneumatic knife gate valve can be divided into single action and double action according to the action form of pneumatic actuator. Double acting principle (air open, air close) : that is, the valve open and close the two - way control. Single acting principle (gas open reset, gas close reset) : play the spring reset function, the valve will open or close automatically when the circuit and gas circuit are cut off or malfunction occurs.
