Butterfly Valve

Double flanged butterfly valve ues the ductile iron materials with good casting performance, low cost, convenient production

Pneumatic actuator butterfly valve use pneumatic actuator more easy maintenance and good adaptability to the environment,the output power is large,and fast opening and closing speed.

Large Size Double Flange Butterfly Valve are our main products

The double eccentric butterfly valve is more resistant to high pressure, has a longer life and good stability. Compared with other valves, the larger the diameter, the lighter the material, and the lower the cost

The eccentric butterfly valve structure is adopted to reduce the friction of the sealing ring and prolong the service life of the valv

Large Size Butterfly Valve use ductile iron material saves material and is lighter than cast steel

1.SS316l Butterfly Valve use the good quality stainless steel more wear resistance, corrosion resistance, high temperature and low temperature resistance.
2.Butterfly valve body sealing surface the use of welding stainless steel cobalt-based alloy sealing surface wear-resistent,long service life.
3.For butterfly valve we could provide different type of operator :worm gear,electric actuator or pneumatic,according to client's requirement.

1. Air Actuated Butterfly Valve use pneumatic actuator the advantage is Compact structure, small size, higher precision
2. Eccentric Air Actuated Butterfly Valve ues double eccentric structure has longer life and better stability
3. This butterfly valve made of high-quality WCB material casting to be stronger and more durable

1. Ductile Iron Wafer Butterfly Valve use ductile iron material good casting performance, low cost, convenient production
2. The butterfly valve with replaceable seat more resistance to acid, alkali, water, superheated water, and water vapor; resistance to polar oil
3. The butterfly valve use the 2Cr13 for stem with good hardness, more wear-resistant

Grooved End Butterfly Valve Small and light, easy to disassemble and repair, and can be installed in any position

The structure of grooved End Butterfly Valveis is simple and compact, and the 90° turn to open and close quickly.

The number of opening and closing tests for grooved butterfly valve is as many as tens of thousands, and the service life is long.

The groove butterfly vlave achieve complete sealing and zero gas test leakage

1.Wafer type cast iron Butterfly Valve size can be 50mm-1000mm
2.Wafer butterfly valve light in weight easy instllation and mintenance
3.Butterfly valve miniminzed operating torque ,energy saving
4.Butterfly valve with good sealing,no leakage under the pressure test

▶▷All parts are covered by fluorine material, which completely prevents corrosion of metal parts by corrosive media.
▶▷The valve seat filled with rubber has good elasticity, is easy to operate, has a long life, and has better sealing.
▶▷The centerline structure can be used for fast cutting off or adjusting the flow, suitable for occasions requiring reliable sealing and good adjustment characteristics.
▶▷The valve body of the fluorine-lined butterfly valve adopts a split type, which is very convenient when replacing the valve stem. The valve can be completed without removing the pipeline.
▶▷Fluorine-lined butterfly valves are widely used in the transportation of liquids and gases (including steam) in various types of industrial pipelines, especially in the use of heavy corrosive media.

▶▷The metal hard seal butterfly valve adopts a triple eccentric sealing structure, the valve seat and the butterfly plate are almost wear-free, and have a tighter and tighter sealing function.
▶▷The sealing ring is made of stainless steel, which has the dual advantages of metal hard seal and elastic seal. It has excellent sealing performance, corrosion resistance and long service life regardless of low temperature and high temperature.
▶▷The sealing surface of the butterfly plate adopts surfacing cobalt-based hard alloy, the sealing surface is wear-resistant and has a long service life.
▶▷The large-size butterfly board adopts the quilted frame structure, which has high strength, large flow area and small flow resistance.
