LUG BUTTERFLY VALVE

Lug type butterfly valve’s design is similar to a 3-piece ball valve. In which one end of the line can be taken off without having an effect on the opposing side. This can be executed by using threaded inserts, flanges, along with two sets of lugs (bolts) that don’t utilize nuts since each flange features its own bolts. It’s also important to note that you don’t need to shut down the entire system in order to clean, inspect, repair, or replace a lug butterfly valve (you would need to with a wafer butter valve). Lug type butterfly valves are usually composed of metal such as ductile iron or steel. They feature threaded tapped lugs positioned on the valve flanges for bolt connections. Lug-style butterfly valves are suitable for end-of-line service but a blind flange is always recommended.  

Mechanism of Pneumatic Actuated Butterfly Valve

The pneumatic Butterfly valve works on a simple mechanism and is easy to use so it has low maintenance, these valves are fitted in mid of fluid flow. There is a disc connected to a center rod, which rotates the disc quarterly to pass through to open and close. This metal disc called Butterfly rotates a quarter turn to allow fluid to pass indefinitely. so the slow opening valve will reduce the flow, and turning the disc to close the valve and flow. This valve is operated by pressurized air which is controlled by a pneumatic actuator fixed on it.  There is no need for any dedicated personal to operate the valve. The pneumatic actuator operates this valve too fast and easily with lower cost and utmost safety. Quality and Testing We supply products of only high quality graded materials and who also follow API standard criteria: API 609 Certificate for Butterfly Valve.

Where to Use Pneumatic Actuated Butterfly Valves

Pneumatic Actuator 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. Liquids like petro-chemicals, Oil, and Gas. The valve is operated by pneumatic actuation allowing fast functioning and safety from fire and short circuits. So it is an electricity efficient operated valve with the lowest cost.

Applications

Butterfly valves are used in diverse industries and applications. Some examples such as pharmaceutical, chemical and oil, food, water supply, wastewater treatment, fire protection, gas supply, fuel handling, and sanitary fittings. Butterfly valves for water are used as control valves in pipelines to shut off water flow. These valves are available in different sizes and are suitable for handling slurries and liquids with relatively large amounts of solids at low pressures. Stainless steel butterfly valves are used in corrosive and marine environmental applications. Stainless steel material is highly durable and resistant to corrosion.
