OKUMURA 616 Butterfly Valves
Friction-Free Performance: Tough New Way to Tame Pressure Up to 16 Bar (232 psi)
The OKUMURA 616 Butterfly Valve features a patented “Touch” seat design that works together with an S-shaped disc to provide smooth, dependable bubble-tight shutoff and and extended service. The design accommodates working pressure up to 16 bar. (232 psi) and flanges comply with ISO, ANSI, BS, AS, DIN and JIS.
S-Shaped Disc Enhances Flow Control
The S-Shaped disc enhances the CV rating and promotes flow control without turbulence. The valve can be operated at the lowest possible operating torque with bubble-tight  shutoff at the maximum operating pressure.

Friction-Free Operation for Low Torque, Long Service 
The patented “Touch” seat design permits the disc to close with virtuality no frictional contact between the disc and the valve seat. 
And so, there is virtuality no wear and tear on the valve’s internal structure. The construction ensures a low torque-to-size ratio and improved in service performance over a conventional design
