Pneumatic type knife gate valve main product overview

the products in the industry have a certain price advantage and technological advantages. Sealing face has two gate, two of the 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, the pneumatic type damper is called elastic disc knife gate valve is closed, sealing surface can only rely on medium pressure to seal, that depend on 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 of the pneumatic type knife gate valve is sealed with mandatory, the pneumatic valve is closed, to rely on outside force forced the ram pressure to the pneumatic seat, to ensure the sealing of sealing face this kind of pneumatic valves shall generally be installed in the pipeline.
pneumatic type knife gate valve drive mode: manual, electric, pneumatic, hydraulic, bevel gear, electric hydraulic and hydraulic drive mode, etc.
shape pneumatic type knife gate valve: stem, non-rising stem two
pneumatic type knife gate valve material: cast iron, cast steel, carbon steel, stainless steel, etc.
the knife type brake lining fluorine pneumatic valve seal: hard seal, soft seal, single seal, double sealed and other sealing material.
enter our country from eighty s. In less than twenty years, its use range from the common areas expanded into wider all walks of life. From power plant of coal mines, conveyor, slag discharge. Development of the urban sewage treatment, from the general industrial pipeline to food, health, medicine and other professional pipeline system. Ultra-thin breaker of the pneumatic valve with its small volume, light weight, small flow resistance, and the advantages of easy to install, easy to remove completely solve the common brake pneumatic valve, pneumatic valve, pneumatic ball valve, flat gate as pneumatic valve, regulating valve, pneumatic valve such as pneumatic butterfly valve of flow resistance, weight big, difficult to install, covers an area of big problems. Breaker pneumatic valve, a large number of gm cut class of pneumatic valve and regulating valve has been replaced. Today, pneumatic valve dosage breaker of the world's biggest is the United States and Japan.
