High quality  Double Plate Wafer Swing Check Valve

1. Product description

1. We are professional Pinless butterfly valve manufacturer, high quality electrical wafer butterfly valve is the introduction of similar designing and manufacturing advanced products and a series of new connection butterfly valve types from the  United States and  Germany.  

2. The Butterfly valve can be installed express, simple, safe, reliable and not subject to restriction on the installation site, facilitating the maintenance of piping and valves. 

3. Besides, the butterfly valve types can reduce noise and vibration, can overcome poor imitation caused by connecting pipelines to different axises, can solve the expansion caused by heat and contraction caused by cold.

4.Widely used in transmission fluid to the drainage pipes, fire, air-conditioning, gas, petroleum, chemicals, water treatment, municipal, pipeline engineering and shipbuilding role as the control fluid.

2. Product features advantages

1. Small in size and light in weight. This electronic valve can be installed easily, simple, safely,  reliably 

2. Not subject to restrictions on the installation site, it is convenient for pipelines and butterfly electro valves types to maintenance

3. The ball-and-socket valve board path causes the valve rotation to be flexible

The butterfly valve types disc is formed according to a complete sphere processing, each part of the packing surface is  a spherical surface part, even the axial packing surface place in the top and the bottom of valve board is not exceptional. Although has contacted, when seal, such the packing surface is quite smooth. Therefore, the moment of the force is reduced, the sealing property is improved, especially the axial seal place friction is reduced, and the butterfly motor operated valve types seat life increases three times.
