Pneumatic Lug Butterfly Valve

Lug type butterfly valve with Pneumatic actuator is one of the most common butterfly valve. The pneumatic lug type butterfly valve is driven by the air source. Pneumatic actuator are divided into single acting and double acting. This kind of valves are widely used in water, steam and wastewater treatment. in different standard, such as ANSI, DIN, JIS, GB.

Product Advantage

It is easy to control the torque value within an appropriate range. It's easy to use a two-section stem without a pin connection. The structure is simple and compact, and the disassembly is convenient.

Novel, reasonable design, light weight, fast opening and closing.

The operating torque is small, the operation is convenient, labor-saving and proficient.

Can be installed in any position, convenient.

The seals can be replaced, the sealing performance is reliable, and the two-way seal has zero leakage.

The sealing material has the characteristics of aging resistance, corrosion resistance and long service life.

Simple structure, good interchangeability and low price.

The lifting lug butterfly valve is also widely used in: steam, air, gas, ammonia, oil, water, brine, alkali, seawater, nitric acid, hydrochloric acid, sulfuric acid, phosphoric acid and other media in chemical, petrochemical, smelting, pharmaceutical, food and other industries On the pipeline as a regulating and shut-off device.

The lug butterfly valve is similar in design to a three-piece ball valve in that one end of the line can be removed without affecting the other side. This can be achieved by using threaded inserts, flanges, and two sets of lugs (bolts) that do not use nuts, since each flange has its own bolt. It is also important to note that the entire system does not need to be shut down when cleaning, inspecting, servicing or replacing lug butterfly valves (requires wafer style butterfly valves).
