JC triple offset butterfly valve design and unique sealing elements provide zero leakage through non-rubbing 90-degree rotation across a wide range of pressure and temperature conditions.
On the basis of preserving primary radical eccentric and axial eccentric, the axis of conical seal surface has been inclined with the center of valve flow path to form angle eccentric. JC tri-eccentric butterfly valve is characterized by compact structure, effective handle and long work life. It can be widely used in oil & Gas, chemical, petrochemical, power station, metallurgy, textile, food, pharmaceuticals,
API FLANGE BUTTERFLY VALVE
B31 – 150Lb / 300 Lb
All Butterfly Valves have
1. Valve design and manufacture as per ASME B16.34-2004.
2. Flange connection as per ANSI BI6.5ASME BI6.47.
3. Valve body structural length as per API 1609-2004.
4. Valve check and test as per API 598.
API WAFER BUTTERFLY VALVE
B32 – 150Lb / 300Lb
All Butterfly Valves are designed with a metallic composite cone beveling.
The JC Triple offset butterfly valve takes advantage of cam effect, thus valve seat could be released from seal ring through the whole switching process and zero friction exists between valve seat and plate seal ring providing friction-free stroking throughout the valve.
API LUG BUTTERFLY VALVE
B33 – 150 Lb / 300 Lb
The unique Valve design and manufacture as per API 609-2004 extends valve life, ensures no over-travel of the disc, allows for a lower torque for actuator to be fitted and ensures bubble tight closure of the valve, resulting in zero-leakage performance.
DIN FLANGE BUTTERFLY VALVE
B31 – PN10 – PN16 – PN25 – PN40
The butterfly plate seal ring is designed as multi layer seal ring. This seal compresses on a radial basis and moves flexibly and elastically.
Optional sealing materials are suitable for different temperature and medium.
DIN WAFER BUTTERFLY VALVE
B32 – PN10 – PN16 – PN25 – PN40
All Triple offset JC valves are provided with three dimensional eccentric sealing structures. The valves are designed and manufactured with unique techniques and dedicated facilities for maximum machined accuracy. This ensures full cone match of sealing pair, and eliminates the intervention and abrasion between sealing faces.
DIN BUTT-WELDING BUTTERFLY VALVE
B34 – PN10 – PN16 – PN25 – PN40
All valves are tested according to API 598 procedures and are strengthened due to metal-to-metal sealing designed to provide essential fire safety along with small switching resistance, reliable sealing performance, reduced sealing face abrasion and a vastly extended valve life. The alloy hard sealing enables withstanding higher pressure and temperature whilst still providing bubble-tight shut off.
