High Performance Lug Type Butterfly Valve

product-510-330

Overview

Butterfly valve is a valve that uses a disc-type opening and closing part to rotate back and forth about 90° to open, close and adjust the fluid channel. Butterfly valves not only have simple structure, small size, light weight, low material consumption, small installation size, small driving torque, easy and rapid operation, but also have good flow adjustment function and closing sealing characteristics. One of the fastest growing valve varieties. Especially in industrially developed countries such as the United States, Japan, Germany, France, and Italy, butterfly valves are widely used. The varieties and quantities used continue to expand, and they are moving towards high temperature, high pressure, large diameter, high sealing, long life, It has excellent regulating characteristics and multi-functional development in one valve. Its reliability and other performance indicators have reached a high level, and it has partially replaced globe valves, gate valves and ball valves. With the advancement of butterfly valve technology, butterfly valves will become the dominant valve form in a foreseeable short time, especially in the fields of medium and low pressure applications of large and medium-sized valves.
