Small and light, easy to disassemble and repair, and can be installed at any position2. The structure is simple and compact, the operating torque is small, and the 90 ° rotary opening is fast3. The flow characteristics tend to be linear and the regulation performance is good4. The connection between the butterfly plate and the valve rod adopts the pin free structure, which overcomes the possible internal leakage point5. 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 times6. The sealing element can be replaced, and the sealing is reliable to achieve two-way sealing7. The butterfly plate can be coated according to the user's requirements, such as nylon8. The valve can be designed into flange connection and clamp connection9. The driving mode can be manual, electric or pneumatic10. Can be installed in any desired position11. Bubble-tight shut off at full pressure rating12. Stem anti-blowout design keep safety in field use13. Extended stem can be selected Offset Butterfly valve SpecificationSize:2"~60"(DN 50~DN 1500)Pressure:Class 150~Class 2500,PN 16~PN 420End Connection:Flanged,BW,Lug,Wafer Main MaterialsCasting Steel:WCB,WCC,WC6,WC9,LCB,LCC,CF8,CF3,CF8M,CF3M,CF8C,4A,5A,6A,CN7M,CW6MC,CW12MW,CU5MCuC,C5,C12,M35-1Special Alloy Steel:Inconel,Hastelloy,Monel Products Standard And Features1.

Test & Inspection:API 598  Feature:1. Triple Offset or Concentric Lining Type2. Low friction between seat and disc3. Zero leakage sealing design4. One piece shaft5. Metal to Metal sealing6. Low torque for compact actuators and long cycle life7. Blow-out proof stem8. Extended stem can be selected9. Locking device can be selected10. Triple eccentric butterfly valves provide performance reliability and quality for critical process applications, steam isolation, and extreme temperature conditions11. 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 cycle12. Low torque for quarter turn operation allows for smaller actuators and lower costs13. Its compact design makes installation easier because the valve is lighter and requires less pipe support14. Triple offset butterfly valve can reduce weight and space and save a lot of cost Lined Butterfly Valve Specification1. Size:2"~40"(DN 50~DN 1000)2. Pressure:Class 150,PN 10,PN 163.
