The type of imported pneumatic valves

the pneumatic valve ( 阀) Is a fluid conveying system in the control unit, a cut-off, regulation, guide, to prevent the reverse flow, voltage regulator, the leakage of the shunt or overflow, and other functions.
used for fluid flow control system of pneumatic valve, pneumatic valve from the simplest as to the extremely complex control system used in all kinds of pneumatic valves, its quite a wide varieties and specifications. Pneumatic valve can be used to control air, water, steam, all kinds of corrosive medium, mud, oil, liquid metal and radioactive medium such as various types of fluid flow. According to the material also can be divided into pneumatic valve pneumatic valve, cast iron cast steel pneumatic valve, pneumatic valve (stainless steel ,,,, etc. ) Pneumatic valve, chrome molybdenum steel, chrome molybdenum vanadium steel pneumatic valve, pneumatic valve, dual phase steel plastic pneumatic valves, such as non-standard custom-made pneumatic valve materials.
according to the function and purpose ( ） Truncation: such as brake pneumatic valve, pneumatic valve, the cut-off cock pneumatic valve, pneumatic ball valve, pneumatic valve, needle type pneumatic butterfly valve, pneumatic diaphragm valve, etc. Truncation type pneumatic valve, pneumatic valve, also known as closed circuit by the pneumatic valve, its role is connected or truncated medium pipeline. Check pneumatic valve, also known as one-way pneumatic valve, pneumatic valve and non-return check pneumatic valve belongs to a kind of automatic pneumatic valve, its role is to prevent the backflow medium pipeline, prevent the pump and drive motor reversal, and the container medium leakage. Pump suction off hand of pneumatic valve also belong to the check valve class. Explosion-proof, pneumatic valve, pneumatic valve of accidents, and etc, the function of the pneumatic valve is to prevent the pipeline safety device or the medium pressure in excess of the prescribed values, so as to achieve the goal of security and protection. Regulating pneumatic valve, pneumatic valve and throttle pressure relief valve, its function is to regulate parameters such as pressure, flow rate of the medium. （ ） Vacuum, such as vacuum pneumatic ball valve, pneumatic valve, vacuum baffle vacuum pneumatic valve, pneumatic vacuum pneumatic valve, etc. Its role is in the vacuum system, which is used to change the direction of air flow, adjust volume size, cut off or connect pipe of the vacuum system components is called vacuum pneumatic valves. （ ） Special purpose: such as pigging pneumatic valve, object completely dynamic valve, pneumatic valve, pneumatic valve exhaust emission, filters, etc. Exhaust pneumatic valve in the pipe system is indispensable auxiliary components, are widely used in boiler, air conditioning, oil and gas, water supply and drainage pipeline. Often installed in the place such as the commanding heights or bend, get rid of extra gas pipeline, pipe road use efficiency and reduce energy consumption.
