OKM 616J / 618H / 622H Butterfly Valves

A product that offers merits through it performance and economical feature. It also reduces torque requirement through its unique OKM seat structure which make it possible to have longer seat ring life.

 

  • Low torque & longer life due to its unique new OKM soft touch seat: A newly developed soft touch seat that presses in with a smooth angle when the disc touches at the rubber seat.
  • A lighter and smaller actuator due to the lower torque requirement: Due to the unique OKM seat development, no other products have its kinds of patented seat structure. With the reduction of its torque requirement, the actuator could be made smaller and lighter.
  • FCD450 as a body material : ( 40A-300A) FCD450 is used as the body for 612X Type C and E in order to strengthen and further improve it.

1.0MPa general-purpose butterfly valve developed from the pursuit of high-quality seal technology

With an integrated body and seat, this valve offers stable performance in any field thanks to features including high pressure, high differential pressure, high flow velocity (6m/s), and high vacuum.

“S-Line Disc” designed with ideal fluid dynamics in mind

OKM’s “S-Line Disc” provides high CV values as well as excellent controllability. In addition, friction-free contact with the disc seat allows for low torque and excellent sealing performance.

“Touch” seat for guaranteed sealing performance, low torque, and long service life

The design allows the disc to crimp against the seat protuberance, thus ensuring excellent sealing performance. And because the disc does not come into contact with the seat until the valve is fully closed, the operating torque is drastically reduced. This makes it possible for the actuator to be both compact and lightweight. Moreover, the “Soft Touch” of the disc against the seat allows for an even longer service life of the rubber seat. In other words, the “Touch” seat design is greatly beneficial not only in terms of performance but also economic efficiency.
