marine or ship use center hydraulic valve clip
Product Description
Butterfly valve, also called the flap valve is a kind of simple structure of the regulator, it can be used for low pressure pipeline medium of switch control which refers to the closed butterfly valve (valve clack or butterfly plate) is a disc, the valve can reach open and close by rotating around the valve, it can be used to control air, water, vapor, mud, all kinds of corrosive medium, oil, liquid metal and radioactive medium such as various types of fluid flow. Its function in the line is mainly to cut off and throttle. Butterfly valve opening and closing is a discshaped butterfly plate, the body rotatesaround its own axis, so as to achieve the aim of opening and closing or adjust.
Advantages
1. Open/close convenient and rapid, saving effort and small fluid resistance, can often operation.
2. Simple structure, small dimension, length short structure, small volume, light weight, suitable for large diameter of the valve.
3. Can transport the mud accumulating the least liquid in the apertures
4. Under low pressure, can achieve good sealing.
5. Adjust the good performance.
6. Wide open seat effective circulation channel area is larger, the fluid resistance is small.
7. Open-close torque is small, due to the rotation axis disc basic equal role by the medium, and the torque in the opposite direction, thus opening and closing the case.
8. Sealing surface materials commonly used rubber plastic so low pressure sealing performance is good.
9. Easy installation.
10. Flexible operation and effort, can choose manual electric pneumatic hydraulic way.
