Diaphragm valve is a special form of cut-off valve, a piece of soft material made of diaphragm is his opening and closing parts, diaphragm to the valve body cavity and bonnet cavity and drive parts separated.Because the diaphragm valve itself structure design characteristics are particularly suitable for ultra pure media or serious pollution, very viscous liquid, gas, corrosive or inert media.When combined with control equipment, diaphragm valve can replace other traditional control systems, especially for solid and easily contaminated inert media.In the operation of the diaphragm valve should pay attention to the rupture of the diaphragm and the diaphragm and disc off and other faults.

Type knife gate valve

Type knife gate valve is a gate opening and closing parts, gate movement and fluid direction perpendicular to the direction, type knife gate valve can be fully open and fully closed, can not be adjusted and the throttle. Ram has two sealing surface, the most common mode of gate valve sealing surface formed two wedge, wedge angle varies with the valve Balance Valvesparameters, usually 50, knife-type gate valve wedge gate can be molded into a whole , called the rigid gate; also be made to produce micro-deformation of the gate, in order to improve its process of, to make up the sealing surface angle deviations arising during processing, this gate is called the Instrumentation Ball Valveselastic-type knife gate valve closed , the sealing surface can only rely on media pressure to seal, in which the medium 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 knife-type gate valve is sealed by Needle & Gauge Valvesforce, that the valve is closed, to rely on external pressure to force the gate to the seat, to ensure the sealing surface of the seal. Knife-type valve is equipped with knife-type gate, has a good shearing, best suited to pulp, powder granules,Safety Relief Valves fibers, etc. difficult to control the fluid, are widely used in papermaking, petrochemical, mining, water, food and other industries . With a variety of seat options, and can be controlled according to site requirements, equipped with electric or pneumatic actuators, valve automation to achieve.Instrument Manifolds Material: cast iron, carbon steel, stainless steel Size range: DN50 ~ DN600 Maximum pressure: 1.0MPa knife knife type gate valve for use with a good shearing, best suited to pulp, powder granules, fibers, etc. difficult to control fluid, are widely used in papermaking, petrochemical, mining, drainage, food and other industries. With a variety of seat options, and can be controlled according to site requirements, equipped with electric or pneumatic actuators, valve automation to achieve. Material: cast iron, carbon steel, stainless steel Size range: DN50 ~ DN600 Maximum pressure: 1.0MPa fmlww1117.
