What is a metal seat flange butterfly valve？

Hard seal flange butterfly valve is also called turning valve. It is a simple structure of the regulator and can also be used for switch control of low pressure pipeline medium. Hard seal flange butterfly valve mainly plays a cutting and throttling role in the pipeline. The opening and closing component is a disc that rotates around its own axis in the body to achieve the purpose of opening and closing or adjusting.

Advantages of the metal seat flange butterfly valve：
1.Low pressure loss
Flange butterfly valve in the fully open position, the only resistance when the medium flows through the body is the thickness of the disc, so the valve pressure loss is small, improve the flow control characteristics.
2.Long service life
Hard seal butterfly valve uses metal seal, which is generally longer than the elastic seal life. It can adapt to a higher temperature environment.
3.Wide range of application
It is suitable for large diameter valve manufacturing. Butterfly valve is not only widely used in oil, natural gas, chemical, water treatment and other general industries, but also widely used in the cooling water system of thermal power plants.
4.Installation is not restricted
Hard seal butterfly valve is not limited by the flow direction of the medium during installation. It has a two -way sealing function and is not affected by the space position. It can be installed in any direction.
