Pneumatic knife type stainless steel gate valve PZ673W

Pneumatic knife gate valve is a pneumatic actuator control valve, in order to achieve the valve opening and closing of a valve. It can be divided into upper and lower parts, the upper part of the pneumatic actuator, the lower part of the valve.

Pneumatic knife-type gate valve is the gate opening and closing pieces, the direction of movement of the gate and the direction perpendicular to the fluid, manual knife-type gate valve can only be fully open and fully closed, can not be adjusted and throttling. Gate has two sealing surface, the most commonly used mode gate valve sealing surface of the formation of two wedge-shaped wedge angle varies with the valve parameters, usually 50, wedge-type knife gate valve can be made into a whole, called the Rigid gate; also available

Pneumatic knife gate valve can be made to produce micro-deformation of the gate to improve its technology to make up the angle of the sealing surface in the process of deviation, this gate is called the elastic gate knife gate valve closed, the sealing surface can only Rely on the medium pressure to seal, that is, relying on the media pressure to the gate of the sealing surface to the other side of the valve seat to ensure the sealing surface of the seal, which is self-sealing.Most of the knife-type gate valve is forced seal, the valve closed , To rely on external force to force the gate pressure to the seat in order to ensure the sealing surface of the seal.

Knife blade gate valve Product Notes and features: knife-type gate valve is the gate opening and closing pieces of the gate, the direction of movement of the gate and the direction perpendicular to the fluid, the knife-type Gate valve can only be fully open and fully closed, can not be adjusted and throttling. Gate has two sealing surface, the most commonly used mode gate valve sealing surface of the formation of two wedge-shaped wedge angle varies with the valve parameters, usually 50, wedge-type knife gate valve can be made into a whole, called the Rigid gate; can also be made to produce micro-deformation of the gate to improve its technology, to make up the sealing surface angle deviation in the processing process, this gate is called flexible gate knife gate valve closed, the sealing surface Can rely on the medium pressure to seal, that is, relying on the media pressure to the gate of the sealing surface to the other side of the valve seat to ensure the sealing surface of the seal, which is self-sealing.Most of the knife gate valve is forced seal, Valve closed, to rely on external force to force the gate pressure to the valve seat to ensure the sealing surface of the seal.

The pneumatic knife type gate valve has the advantages of simple and compact structure, reasonable design, light section material, reliable sealing, light and flexible operation, small volume, smooth channel, small flow resistance, light weight, easy installation and easy dismantling, etc., working pressure 1.0MPa -2.5MPa, the use of temperature -29-650 ℃ under normal circumstances. The knife-type gate valve with a shear function, can be scraped on the sealing surface of the adhesive material, automatic removal of debris, stainless steel gate to prevent corrosion caused by leakage of the seal.
