ISO 5211 ACTUATOR ASSEMBLY
The ZPR770Y eccentric rotary control ball valve,also called C-type valve orcamflex valve.It features a straight-through flow path design in the valve body,with an eccentrically rotating spherical disc that provides excellent flow-guiding characteristics.
The valve cavity has no flow dead zones,resulting in low fluid resistance while maintaining effective self-cleaning of the disc surface.
When opening,the disc instantly separates from the seat(>0.05mm gap at 3°opening)due to proper eccentric design,minimizing wear between components and requiring low operating torque.During closing,the eccentric mechanism creates a progressive wiping action(0°-3°)that enhances self-cleaning between disc and seat.After 90°rotation,the spherical surface rotates sideways away from direct fluid impact,ensuring effective protection.
This eccentric rotary control valve offers advantages of low fluid resistance,wide adjustable range,and small stable torque,making it particularly suitablefor controlling and regulating media such as slurries,powders,crystals,andsulfides in pipeline transportation,etc.
| Features | Description |
| One-Piece Body | Monobloc body design with integral wafer/flange connections,offering superior rigidity to prevent deformation and external leakage |
| Self-Centering Structure | The seat sealing surface and ball feature self-centering capability,facilitating routine maintenance |
| Trunnion-Mounted Ball | The trunnion-mounted ball design resolves centering,positioning,and erosion protection issues for the stem-disc assembly,Suitable for high-purity media applications |
| Flat Sealing System | A precision-machined flat metal-to-metal seal between the seat and body replaces traditional gaskets, forming a rigid sealing structure |
| Shape-Memory Alloys Seat |
The shape-memory alloy seat(elastic seat)achieves bidirectional high-pressure sealing while compensating for disc/seat wear,featuring self-cleaning and shearing capabilities during shut-off |
| Superior Sealing | The ball and seat surfaces are hardfaced with Stellite or other wear-resistant alloys, delivering superior abrasion resistance |
| Standard Mounting Platform |
Design with deep packing box and cast bracket isolates actuator from body heat,maintaining ISO 5211 compliance for universal pneumatic/electric actuator compatibility |
