butterfly valve

Epdm Seat Butterfly Valve use ductile iron material and EPDM for sealing materials for the temperature -10°C to 120°C For the butterfly valve will test before left the factory,and Shell test : 1.5 times rated pressure,seal test 1.1 times rate This butterfly valve usd pneumatic actuator Fast opening and closing speed and Easy maintenance and good adaptability to the environment. we can choose pneumatic actuator according to customer's require

1.Electric butterfly valve body only needs a small installation space, and the task principle is easy and reliable 2.Motorized Butterfly Valve power supply：AC220、380V/DC24、220V 3.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

Rubber lined butterfly valve small operating torque, convenient operation, labor-saving and smart. 6 Inch Butterfly Valve can be installed in any position and is easy to maintain. The seal of the butterfly valve can be replaced, and the sealing performance is reliable to achieve two-way sealing with zero leakage.

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
