COVNA HK59-D-GF Pneumatic three eccentric butterfly valve, the valve body part adopts three eccentric structure, the valve plate and sealing mechanism are unique in design, with excellent cutting performance and durability, as well as dual functions of cutting and adjusting. It is small in size, light in weight, economical and practical, and easy to maintain; Low friction, high efficiency, high thrust and good safety; Simple, eye-catching, reliable and integrated travel indication, combined installation of limit switch and solenoid valve, no external pipeline, reducing leakage point; It can realize bidirectional sealing function, which can be adjusted and cut off
A variety of actuator forms are available for selection to meet the requirements of different users; The design of flexible and combined actuator (manual mechanism) can ensure the free installation and flexible control in all directions
