a lot of new to the valve industry customers, must have such a question, is how should according to the needs of customers to choose the most suitable for his valve?

here will tell you about the electric ball valve with electric butterfly valve each its own characteristics, we will know how to choose.

the choice of generally small electric ball valves, large diameter with electric butterfly valve. Because of small butterfly valve is to be custom-made, need to open mold, so the cost is relatively high.

electric butterfly valve has simple structure, low cost, adjustable range is larger, ball valve usually applies to the class without pellet impurity of the liquid, gas, fluid pressure loss is small, sealed performance is good.

1, the flow control accuracy is not high fluid pressure small place with butterfly valve, butterfly valve is one of the most simple valve! Mainly used in regulating air volume and powder through put on!

in view of the liquid gas control fluid pressure, flow effect is good, requires quick open to completely cut off traffic with the ball!

2, and ball valve is spherical sealing between metal and metal, the machining accuracy is high, is generally used for pressure, valve, temperature impact is bigger, sealed strict, diameter is not very big, such as: pulverized coal pipe and air pipe and so on.

electric butterfly valve is flat seal between rubber and metal, machining accuracy is lower, generally used to facilitate control flow, low temperature, is not very strict, larger diameter of water pipe.

3 ingeneral, high temperature, the characteristics of the butterfly valve for pressure range is higher also, nominal valve size is big, the body is made of carbon steel, the sealing face of valve plate surface wear-resisting rubber are adopted. Butterfly valve has simple structure, sealing ring, which generally remove replacement is more convenient. In full open or full close, the body through the sealing surface and the dielectric isolation, medium by, do not cause the erosion of the body.

ball valve fluid resistance small, its resistance coefficient with section of equal length. Compact and reliable, the widespread use of plastic ball valve sealing surface of materials, good sealing, has been widely used in vacuum system is easy to operate, open and close quickly, from open to close just rotate it 90 & deg; Convenient, facilitate long-distance control and maintenance.

what has been discussed above, I believe you on how to choose the butterfly valve and ball valve has a new understanding. Zhejiang valve as a domestic high-end Industrial Valves manufacturer, always respond to national policy and called for, committed to researching, developing and manufacturing electric butterfly valve, stainless steel ball valve, discharge valve, electric gate valves, stainless steel gate, stainless steel valve, stainless steel check valve, high pressure gate valves high-quality let customer trust of good valve, the valve to keep traditional valve product sales profits to escort for the innovation research.

Currently there is a global trend growing. People are more conscious about cast iron valve and are seeking alternatives to traditional solutions.
