High sealing performance achieved with a heart-shaped self-seal! Introducing a long-lasting cast iron butterfly valve.
The "C201R type" features a double eccentric (double off-center) design for the disk's drive axis, and since the disk and seat remain in non-contact until just before fully closed, it is a cast iron butterfly valve with minimal seat wear and a long lifespan. The seat is designed with a centering feature on the contact surface, creating a self-sealing mechanism that generates contact pressure on the disk's sealing surface due to fluid pressure, allowing for efficient sealing from vacuum to high pressure. Additionally, during maintenance, the seat can be easily replaced by simply removing the seat cover. 【Features】 ■ Long lifespan due to double off-center mechanism ■ High sealing performance with centering self-seal ■ Easy maintenance *For more details, please refer to the catalog (P11-P17) or feel free to contact us.
