V – NOTCH BALL VALVE SERIES-310

P N E U C O N DESIGN AND PREFORMANCE FEATURES

A Shearing effect between the ball and seal ensures tight shut-off, even on fibrous slurries. The unrestricted, straight – through flow design provides high capacity and wide rangeability. Precise contouring of the V-notch balls provides a nearly equal percentage characteristic. Replaceable ball seal and back up ring for added rigidity. Ball machined to a super smooth finish, hard – chrome plated and polished to increase ball

seal life. High Cv to body size ratio.

INSTALLATION The valve should preferably be installed with actuator vertically above or below the valve body. It can be installed in a horizontal or angled position if actuator is suitably supported. Necessary clearance should be provided above the actuator to permit servicing. The flange bolts are to be tightened evenly to avoid placing strain on the body. The inlet of air pressure regulator (Air set) should be connected to the pneumatic supply line. Supply pressure to the diaphragm actuator should be either 1.5 kg/cm² (20 psig) or 2.5 kg/cm² (35 psig) as per indication on the nameplate. For cylinder actuator, supply pressure specified. For control applications, the air set and valve positioner are mounted, piped and adjusted at the factory.

Final check After installation, check the valve operation for full stroke travel as indicated on the nameplate, check for leaks in air line connection. Open and close the valve two or three times to ensure proper operation. Before commissioning the process flow, it is essential to flush clean the piping properly. Ball valves require minimum maintenance for its operation. Apply a few drops of oil on the exposed guides and bushings, Hand wheel, if present, must be greased periodically.
