A PTFE lined butterfly valve is a rotary valve that uses a disc as the closure member. The disc shaped closure member is rotated through 90 or there about to open or close the passage. The disc of PTFE lined butterfly valve closes against a ring seal to close off the flow.

PTFE lined type butterfly valve is one type of central lined butterfly valve, which is one normal type of butterfly valve in need of big quantity. PTFE lined butterfly valve is mounted between two matching flanges of the piping with bolts and nuts.

A high-performance PTFE lined butterfly valve is a quarter-turn valve best suited for handling large amounts of liquids or gases. PTFE lined butterfly valves are easy to handle and are used in many flow control and throttling applications.

Lined butterfly valves are designed for corrosive service. The reliable lining PTFE or PFA ensures optimal permeation protection. Our high-performance PTFE lined butterfly valves are ideally suited for the stringent performant requirements demanded with isolating and controlling wet and dry chlorine

Pipeline medium are becoming much more complex in modern anti-corrosion pipeline. As such, valve requirements are getting complicated as well. Among all the anti-corrosive valves especially the traditional valves with special material like inconel alloy valves

The sealing principle and structural characteristics of flanged butterfly valves are the same as those of ordinary centerline butterfly valves.

A butterfly valve is a quarter-turn rotary motion valve that is used to stop, regulate, and start the flow. Butterfly valves are a quick open type. A 90° rotation of the handle can completely close or open the butterfly valve.

Flange butterfly valve refers to a type of butterfly valve whose connection method is flange. This connection method is considered the most common one at present.

The butterfly plate of the flanged butterfly valve is installed in the diameter direction of the pipeline. The flanged butterfly valve is simple in structure, small in size and light in weight.

The opening and closing part of the flanged butterfly valve is a flange. The movement direction of the flange is perpendicular to the direction of the fluid. The flanged butterfly valve can only be fully opened and fully closed and cannot be adjusted or throttled.
