Knife gate valve due to use of a knife-type gate, has a good shearing, best suited to slurry, powder granules, fibers, etc. difficult to control the fluid is widely used in papermaking, petrochemical, mining, drainage, food and other industries. With a variety of seat options, and can be based on on-site control requirements, equipped with electric or pneumatic actuators to achieve the valve automation. Material: cast iron, carbon steel, stainless steel Size range: DN50 ~ DN600 Maximum pressure: 1.0MPa knife gate valves for use of a knife-type gate, has a good shearing, best suited to slurry, powder granules, fibers, etc. are difficult to control of the fluid, are widely used in papermaking, petrochemical, mining, drainage, food and other industries. With a variety of seat options, and can be based on on-site control requirements, equipped with electric or pneumatic actuators to achieve the valve automation. Material: cast iron, carbon steel, stainless steel Size range: DN50 ~ DN600 Maximum pressure: 1.0MPa Knife-type valve product use and characteristics of Attention: Knife-type valve is a gate to open and close cases, ram direction of motion perpendicular to the direction of the fluid, knife-type gate valve can only be fully open and fully closed and can not to make adjustments and cut expenditure. There are two gate sealing surface, the most common mode of gate valve sealing surface to form two wedge-shaped, wedge-shaped angle with the valve parameters vary, usually 50, wedge-type knife gate valve of the gate can be made a whole , called the rigid damper; also be made to produce small quantities of deformation gate in order to improve their craft-oriented, to make up the sealing surface angle in the processing error generated in the process, this gate is called the elastic-type knife gate valve is closed , sealing surface can only rely on media pressure to seal, that is, to rely on media pressure to ram pressure to the other side of the sealing surface of the valve seat to ensure the sealing surface of the seal, which is a self-sealing. most of the knife-type gate valve is the adoption of compulsory sealed, that is, the valve is closed, we must rely on outside pressure to force the gate to the seat in order to ensure the sealing surface of the seal.
