Butterfly valves have been around for a long time, and are used for a variety of applications. They made their first appearance during the 1930s, and have been utilized by several industries ever since. Often made out of cast iron, butterfly valve's name is based from the functionality of its disc.
The wafer butterfly valve is one of the most common types of valves in industrial pipelines. The structure of wafer butterfly valve itself is relatively small. It is only necessary to put the butterfly valve in the middle of the flange at both ends of the pipe, and use the stud bolt to pass through the pipe flange and the pair.
Valves are the most common equipment in chemical companies. It seems easy to install valves, but if they are not implemented in accordance with the re...
The manual valve is a valve operated by the handle and the hand wheel, and is a commonly used valve on the equipment pipeline.

MINOTAUR series replaceable seat high performance butterfly valve
1. The difference between the valve ball and butterfly valve is that the ball valve is a ball around its axis for rotation, and the butterfly valve is a piece of plate around its axis for rotation, you can adjust the flow through the opening degree, the ball valve can not adjust the flow through the opening degree.
2. Butterfly valve is characterized by fast opening and closing speed, simple structure, low cost, but the tightness and pressure capacity is not good. The characteristics of ball valves and gate valves are similar, but, by the volume and open - close resistance restrictions, it is difficult to achieve large diameter.
3. The structural principle of butterfly valve is especially suitable for the installation of butterfly plate of large-diameter valve in the diameter direction of pipeline. In the butterfly valve body cylindrical channel, disc shaped disc around the axis of rotation, rotation Angle between 0°~90°, rotation to 90°, the valve is fully open. Its structure is simple, the cost is low, the adjustable range is large. Valve ball is usually suitable for non-granular impurities of liquid, gas, fluid pressure loss is small, good sealing performance, high cost. Comparatively speaking, the valve ball seal is better than the butterfly valve. Valve ball seal is on the seat for a long time extrusion on the sphere, it is faster than half valve ball wear, valve ball seal is usually used flexible materials, it is difficult to use in high temperature and high pressure pipeline.
4. Butterfly valve seal with rubber as the intermediary, it is far from the half ball valve, valve ball, gate valve metal hard sealing performance. Half a sphere, after long-term use of valve seat can have traces of wear, it will continue to be used, by adjusting the stem and packing in the process of opening and closing valve stem just rotate 90 °, there were signs of leak, compression packing gland bolts again a few, packing can be realized without leakage, while other valves is still a small leak reluctantly, big leaks in the valve.
5 valve ball in the process of opening and closing by the seat at both ends of the holding force under the operation, it is greater than the half valve ball opening and closing torque, the larger the nominal diameter of the opening and closing torque difference is more obvious, butterfly valve opening and closing is to overcome the deformation of rubber to achieve, the greater the torque. And gate valve, globe valve operation time is long and laborious. Valve ball and plug valve is the same type of valve, valve ball only its closing part is a ball, the ball around the center line of the valve body for rotation to open, close a valve. Valve ball in the pipeline is mainly used to cut off, distribute and change the flow direction of the medium.
