Butterfly valve is one of widely used industrial valves in pipelines to open, close, and regulate the flow rate of the medium, like water,gas, oils,etc.Butterfly valve has simple structure, small size, light weight, and is only consist of few simple components, like valve body, valve seat, valve disc, valve stem,etc; Butterfly valve can realize quick opening and closing through rotating only 90°, it has great flow regulating performance;
According to end connections, there are wafer type butterfly valve and flange type butterfly valve.
for flange type butterfly valve, there are single flange butterfly valve, and double flange butterfly valve, telescopic flange butterfly valve, U type flange butterfly valve; today we are going to introduce what is the U type double flange butterfly valve:Â
Introduction of U type flange butterfly valve:Â
The U shaped flange butterfly valve adopts the top-loading structure, which reduces the quantity of the connecting bolts of the valve body under the condition of high pressure and large diameter, which enhances the reliability of the butterfly valve and overcomes the influence of the system own weight on the normal operation of the valve.Â
The main technical parameters of U type flange butterfly valve:Â
The nominal diameter range of U type flange butterfly valve:
DN50mm-DN2000mm;Â
The nominal pressure range of U type flange butterfly valve:
PN1.0Mpa-PN1.6Mpa;Â
The working temperature range of U type flange butterfly valve:
 ≤80℃.Â
The application of U type flange butterfly valve:
U type flange butterfly valves are widely used in water conservancy, chemical, pharmaceutical, electric power and other industries, and are used for opening and closing on pipelines of steam, water, and oil mediums;Â
