Stainless Steel knife gate valve(Knife Gate Valves/API gate valve)

Knife Gate Valve Product Description: Knife gate valve opening and closing member is, the direction of movement of the fluid direction perpendicular to the gate, knife gate valve can only be fully open and fully closed, can not be adjusted and the throttle. Knife gate valve is mainly made up of body, O-rings, gate, stem, frame and other components. Wafer knife gate valve integrated structure, small size, light weight; completely open channel, you can prevent the deposition of the media in the valve, the use of replaceable seal structure, a change in general slurry valves and knife gate valve maintenance difficult problem. Body material cast from the traditional replace became ductile iron, better corrosion resistance, effectively extending the service life.
Knife gate valve has two sealing surfaces, sealing surfaces most common mode of gate valve wedge formation, the wedge angle with the valve parameters vary, usually 50, wedge type knife gate valve can be made into a whole, called the rigid gate; also be made to produce small quantities of deformation gate in order to improve its process of, to make up the sealing surface angle deviations arising during processing, this gate is called the flexible gate knife gate valve is closed sealing surface can only rely on media pressure to seal, which rely on media pressure to ram pressure to the sealing surface of the other side of the seat to ensure the sealing surface of the seal, which is self-sealing. Most knife gate valve is sealed by force, that the valve is closed to rely on external pressure to force the gate valve to ensure that the sealing of the sealing surface.   Knife Gate Valve Applications: Knife gate valves due to the use knife gate, has a good shearing, best suited difficult to control fluid slurry, powder aggregates, fibers, etc., it is widely used in papermaking, petrochemical, mining, drainage, food and other industries. Knife gate valve with a variety of seating options, and can be based on the needs of field control, equipped with electric devices or pneumatic actuators, valve automation to achieve.   Knife gate valve advantages: 1. The fluid resistance, sealing surface by erosion distressed medium and small brush.
2. The knife gate valves open and close more effort.
3. The medium flows unrestricted, non-spoiler, without reducing pressure.
The valve body is simple structure, length short, good manufacturing processes, a wide range.
