1. It is designed and manufactured with a new structural form of welding the midline disc plate and the short structural steel plate.It has the advantages of compact structure,light weight,easy installation, small flow resistance,large flow volume,avoiding the influence of high-temperature expansion and convenient operation
2. Reliable sealing,convenient operation,opening and closing fast.
3. This kind of valve with no flange, which makes pipe elegantly and binding up conveniently
4. It adopt triple offset elasticity or multiple layers hard sealing configuration, the hermetical capability can reach to reliable sealing performance
5. The sealing of disc can be replaced by loosening the disc ring bolts, saving the cost of the valve.
6. The ends of valve inlet port and outlet port has the annular boss, which is conducive to the valve and pipe welding heat absorption and diffusion
4. Optional locking device
5. Optional extended stem
6. Low torque enables the compact actuator and a long cycle life

2.Face to Face:ASME B16.10/API 609
3.End Flange:ASME B16.5/ASME B16.47
4.Butt welded ends:ASME B16.25
5.Inspection & Test:API 598
Features:
1. Small and light, easy to disassemble and repair, and can be installed at any position
2. The structure is simple and compact, the operating torque is small, and the 90 ° rotary opening is fast
3. The flow characteristics tend to be linear and the regulation performance is good
4. The connection between the butterfly plate and the valve rod adopts the pin free structure, which overcomes the possible internal leakage point
5. The outer circle of the butterfly plate adopts spherical shape, which improves the sealing performance and prolongs the service life of the valve. There is still zero leakage after opening and closing under pressure for more than 50000 times
6. The sealing element can be replaced, and the sealing is reliable to achieve two-way sealing
7. The butterfly plate can be coated according to the user's requirements, such as nylon
8. The valve can be designed into flange connection and clamp connection
9. The driving mode can be manual, electric or pneumatic
10. Can be installed in any desired position
11. Bubble-tight shut off at full pressure rating
12. Stem anti-blowout design keep safety in field use
13. Extended stem can be selected

4. BW ends:ASME B16.25
5. Test & Inspection:API 598
Feature:
1. Triple Offset or Concentric Lining Type
2. Low friction between seat and disc
3. Zero leakage sealing design
4. One piece shaft
5. Metal to Metal sealing
6. Low torque for compact actuators and long cycle life
7. Blow-out proof stem
8. Extended stem can be selected
9. Locking device can be selected
10. Triple eccentric butterfly valves provide performance reliability and quality for critical process applications, steam isolation, and extreme temperature conditions
11. A two-way zero leakage closure with a metal seat provides sealing integrity that was previously associated only with soft seated valves, even after a long cycle
12. Low torque for quarter turn operation allows for smaller actuators and lower costs
13. Its compact design makes installation easier because the valve is lighter and requires less pipe support
14. Triple offset butterfly valve can reduce weight and space and save a lot of cost
