■ introduction

The valve has the advantages of quick installation, simple and reliable, light weight, flexible operation and convenient maintenance. Moreover, it has good sealing performance and fast connection with pipe fittings. The valve has the advantages of fast installation, simple installation and no limitation of installation site. It is convenient for the maintenance of pipelines and valves. It has the function of vibration isolation and shock absorption. It can solve the shortcomings of thermal expansion and cold contraction of pipeline caused by temperature difference. The valve can be used in water supply and drainage, fire control, air conditioning, molten gas, petroleum, chemical, water treatment, municipal, shipbuilding and other pipeline engineering as control fluid.

characteristic

1. Groove butterfly valve has the advantages of compact structure, small volume, light weight, flexible operation and convenient maintenance.

2. The sealing performance is reliable and not limited by medium flow direction (bidirectional seal).

3. It has large flow area, small flow resistance coefficient and large circulation capacity.

4, reasonable structure, reliable sealing, easy operation. The butterfly plate is made of integral rubber, which has the characteristics of anti-aging, radiation resistance and durability. It is suitable for water, oil, mud and natural gas pipelines with working temperature less than 120c as opening and closing and regulating devices for controlling medium flow.
