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.

Large flanged butterfly valves are usually equipped with gearbox type actuator, where the handwheel is connected to the stem via a gearbox. This will reduce the force but at the same time reduce the speed of the operation. The flanged butterfly valve should be installed in the open position.

Flanged butterfly valve is a kind of butterfly valve. It is the same as the flanged butterfly valve, which is another common connection method of butterfly valve and has a wide range of uses. The disc of flanged butterfly valves is a plate, swinging with valve shaft to turn on or off valves.
