TJL Industry Group deliver success where time and money are important to our customers' needs. Its valves meet the industry requirements for normal valves: ISO9001, CE, NSF, TS, WRAS. Since the company establishment, it has produced a large number of valves, especially butterfly valves. These years, it has manufactured new butterfly valves to replace old ones. They pass more than 10.000 tests at  PN16. A part of eccentric butterfly valves it produced are small in size and light in weight, easy to install and maintained. By moving the disc off the centerline of the butterfly and a few other mechanical tricks the offset, a valve can may reduce wear when seating and unseating, Double offset butterfly valves are reliable butterfly valve too for handling higher temperature and pressure applications.

A butterfly valve can be used in many different fluid services and they perform well in slurry applications. The following are some typical applications of butterfly valves: | Cooling water, air, gases, fire protection etc | Slurry and similar services | Vacuum service | High-pressure and high-temperature water and steam services.

Advantages of butterfly valves are rendered below:

Compact design requires considerably less space, compared to other valves, light in weight, quick operation requires less time to open or close, available in very large sizes, low-pressure drop and high-pressure recovery.

Disadvantages of Butterfly valves are rendered below:

Throttling service is limited to low differential pressure, cavitation and choked flow are two potential concerns, disc movement is unguided and affected by flow turbulence.
