Cast Iron Butterfly Valve "C201R Type"
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, allowing the disk and seat to remain in non-contact until just before full closure, resulting in minimal wear on the seat and a long lifespan for this cast iron butterfly valve. 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, enabling 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.
