The classification of pneumatic butterfly valve

    Chinabase Machinery is a group of manufacturing facilities, offering one-stop solution for mechanical power transmission products in China. We can supply a full-range of power transmission products, such as chains, sprockets and plate wheels, pulleys, gearboxes, sprocket gear，motors, couplings, gears and racks. Our product range also covers locking assemblies (clamping elements/locking device), taper bushes, QD bushes, bolt-on hubs, torque limiters, shaft collars, motor bases and motor slides, chain detachers, chain guides, universal joint, rod ends and yokes.

    Pneumatic butterfly valve is a pneumatic actuator and valve.Pneumatic butterfly valve is a circular rotation with orange butterfly valve plate to open and close, to enable the action of pneumaticvalve main shut-off valve used to do, can be designed to have asection of the valve regulating or the function and regulation, thebutterfly valve in the low pressure large caliber pipe is used more and more. 

    Pneumatic butterfly valve classification: stainless steelpneumatic butterfly valve, hard seal pneumatic butterfly valve, soft seal pneumatic butterfly valve, pneumatic butterfly valve steel.

     Specific classification

    Pneumatic butterfly valve flange, flange type pneumatic butterfly valve the product made of rubber seal butterfly valve and carbon steel or stainless steel valve plate, a valve rod. Apply to the temperature below 80 ℃ to 120 ℃ such as food, chemical,petroleum, electric power, textile, paper and other water supply and drainage, gas pipes to regulate the role of flow and closure of media.

    Pneumatic butterfly valve is a valve (valve plate) rotating aroundfixed axis perpendicular to the channel, the piston type double orsingle action (spring reset) pneumatic actuator and the butterflyvalve, belonging to the rotating high performance control or cut off the valve, the valve is used with electric, pneumatic valve positioneror electromagnetic valve, air filter regulator, limit switch (valve position), which can realize the fluid process pipeline in theproportion regulation and two cut-off control, automation control so as to achieve the parameters on the fluid flow, pressure,temperature, liquid level etc..

     Pneumatic clip on butterfly valve, novel structure, body structure to meet the short distance pipeline narrow space and the formation ofthe clamp type structure, the external zero leakage, internal leakage in line with national standards.

    Pneumatic butterfly valve, with flange connection, the clamp, the sealing is lined with NBR, EPDM, heat resistant ethylene propylene rubber, natural rubber, chloroprene rubber, fluorine rubber, PTFE,according to media and chemical properties have a more rational choice.

    Pneumatic fluorine valve, corrosion-resistant fluorine valve using the bisection valve combination two piece, the valve seat and valveliner valve integration, work, only the full plastic seat and plastic lined butterfly plate contact with the media, the product can withstand "any medium corrosion in molten alkali metal andelemental fluorine" outside, where D71F46 stem and disc board(forging) as a whole, the surface is uniformly coated with a layer of FEP. The channel of the valve body inner surface is smooth, fluid resistance small, high CV value, flow capacity, torque is moderate,the use of four seal structure and the elastic gasket seat with SIrubber with high temperature aging in sealing surface, all to achieve zero leakage medium.

    Pneumatic butterfly, characteristics, there is a slit left valve plate and valve seat, the product is suitable for the use of poor air circulation in the environment.

    The pneumatic telescopic butterfly valve and its main features:novel design, reasonable, unique structure, light weight, convenient operation, rapid opening and closing; telescopic butterfly valve canbe adjusted and the closure effect, compensate the pipelinetemperature generated by thermal expansion and contractionfunction, but also for the installation and replacement, repair valves provide a convenient. Characteristics of sealing adjustablereplacement, reliable sealing performance.
