1.What is Pneumatic Lug Butterfly Valve

A pneumatic lug butterfly valve is a mechanism that regulates the flow of materials within large pipe diameters by the quarter-turn rotation of a disc. The valve is driven by pneumatic and connect with the pipe by lug.
A rod feeds through the center of a disc and this rod is connected to an actuator that controls the motion of the disc. The disc position is either parallel or perpendicular to the flow of media. A butterfly valve differs from other valves because the disc is always in the flow causing a pressure change for any position of the valve.

2.Where to use the Pneumatic Lug Butterfly Valve

Pneumatic lug Butterfly Valves are generally used for liquid and slurry materials. These are very popular in the valve industry because of their easy to use and simple mechanism. Pneumatic Butterfly Valves are very useful to control highly inflammable liquids like petro-chemicals, Oil, and Gas. It is operated by Pneumatic which allows fast functionality and safe from fire and electric short circuits. So it is an electricity efficient operated valve with the lowest cost.


3.Where is the butterfly valve located

 For butterfly valve parts orientation, there are some standard guidelines. The butterfly valve needs some distance from other parts such as pumps, elbows, and other valves – 6 pipe diameter separation is ideal.
Usually, the butterfly valve is installed with the valve stem oriented vertically with the actuator directly above it, but in some cases, the stem is situated horizontally instead. When connected to a pump or check valve, there must be clearance for the disc so it doesn’t interfere with other parts nearby.


4.Features of Pneumatic Lug Butterfly Valve

a)Small and light, easy to disassemble and repair, and can be installed in any position.
b)The structure is simple and compact, the operating torque is small, and the 90° turn to open quickly.
c)Flow characteristics tend to be straight, with good regulation performance.
d)The butterfly plate can be sprayed with a coating layer according to user requirements, such as nylon or PTFE.
e)The seal can be replaced, and the seal is reliable to achieve two-way sealing.
f)The outer circle of the butterfly plate adopts a spherical shape, which improves the sealing performance and prolongs the service life of the valve. It still maintains zero leakage when opening and closing more than 50,000 times under pressure.
