RV series is quarter turn control valve mainly recommended for throttle service, segment ball valve combines globe valve control with the efficiency of a rotary ball valve.
Segment Ball is in V-notch design with strong cutting force and self-cleanness, especially suitable for control of medium containing fiber and tiny solids. Segment Ball Valve was from pulp and paper industry. By research and development the segment ball valve is extended to other industrial such as petrochemical, petroleum, chemical, fiber, power, metallurgy, pharmacy, environmental protection etc.
Herewith a breakdown and explanation on how the segmented ball valve is compiled and operates;
FEATURES
Precise contouring of the V-notch provides excellent control characteristics for an extensive variety of flow applications. Splined connection between t h e shaft and ball ensures precise control and low hysteresis. Detachable seat retainer design provides easy access to trim parts of valves through inlet of valve by simply removing the screws of retainer. therefore, easy maintenance is ensured which saves user lots of costs as seat spares can be kept instead of changing the entire valve body. Superior trunnion bearing technology is engineered for excellent abrasion resistance. Rugged self-adjusting metal seated option is ideally suited for high temperature applications or slurries. Spring loaded seat maintains constant contact with the ball, giving enhanced sealing performance. Shearing action between ball and seal promotes smooth ,non-clogging operation-perfect for fiber or slurry application.
