The performance characteristics of pneumatic valve stainless steel knife gate

stainless steel pneumatic knife gate valve type knife gate, has good shearing action, the most suitable for paste, powder materials, such as fiber is difficult to control the fluid flow, widely used in papermaking, petrochemical, mining, water drainage, food and other industries. Has a variety of pneumatic valve seat to choose from, and can be on the basis of field control requirements, equipped with electric or pneumatic actuators, pneumatic valve automation operation.

use the matters needing attention and its characteristics: imported stainless steel pneumatic knife gate valve opening and closing is ram, ram movement direction and perpendicular to the direction of flow of imported pneumatic knife gate valve can only be fully open and close, not to adjust and throttling.

the damper has two sealing surface, the two most commonly used model of pneumatic valve gate sealing surface form a wedge, the wedge Angle vary with parameters of pneumatic valve, usually, pneumatic type wedge knife gate valve disc can be made into a whole, is called a rigid disc; Can also make it generates trace of deformation of ram, in order to improve the manufacturability, make up for the sealing surface Angle in the process of our processing deviation, this damper is called elastic brake.

stainless steel pneumatic knife gate valve is closed, sealing surface can only in accordance with the medium pressure seal, that in accordance with the medium pressure, the disc will be to the other side of the pneumatic valve seat sealing surface pressure to ensure that the seal face seal, this is the seal.

most pneumatic type knife gate valve is sealed with mandatory, namely the pneumatic valve is closed, want to rely on outside force forced the ram pressure to the pneumatic valve seat, to ensure the sealing surface sealing.

stainless steel pneumatic knife gate valve features:

, sealing effect is good, U gasket has good elasticity.

and full size design, through the ability.

, good effect of brake is broken, can effectively solve the containing block, particles and fibers medium brake break leakage phenomenon.

and convenient maintenance, no need to remove the pneumatic valve can replace pneumatic valve seal.
