Stainless Steel Material Triple Eccentric Hard Seal Flanged Butterfly Valve

Use:

This valve can be used for blocking, sealing and regulating the flow rate on pipelines and equipment with corrosive media.When the valve is fully open, the flow rate of the media in the pipeline shall not be more than 5m/s.

Introduction

Stainless steel butterfly valve (also known as stainless steel flap valve) adopts three eccentric multi-level metal hard sealing structure, which is widely used in gold treatment, electric power, petrochemical, water supply and drainage, municipal construction and other industrial pipelines with medium temperature ≤ 425 ℃ for regulating flow and carrying off fluid. The valve adopts three eccentric structure, and the sealing surfaces of valve seat and disc plate are made of stainless steel with different hardness and good performance Corrosion resistance and long service life. The opening and closing part of butterfly valve is a disc-shaped butterfly plate, which rotates around its own axis in the valve body, so as to open, close or adjust the valve, which is called butterfly valve. The butterfly valve is usually less than 900 from full opening to full closing. The butterfly valve and the butterfly rod are not self-locking. In order to locate the butterfly plate, a worm gear reducer should be installed on the valve rod. The use of worm gear reducer can not only make the butterfly plate have self-locking ability and stop the butterfly plate at any position, but also improve the operation performance of the valve. The industrial butterfly valve is characterized by high temperature resistance, high applicable pressure range, large nominal diameter of the valve, carbon steel body and metal ring instead of rubber ring. Large high temperature butterfly valve is made of steel plate welding, which is mainly used for smoke and air duct and gas pipeline of high temperature medium.
