Ball valves perform a quarter turn on/off or modulating function. A flow-controlling ball located within the body of the valve contains a hole through its center along one axis, which connects the inlet and outlet ports of the body. The ball itself is held in place by, and rotates 90º within, PTFE seats. These provide permanent lubrication and keep the valve bubble-tight. They are backed by elastomeric cushions, which provide pressure against the ball and, at the same time, compensate for wear. Elastomer O-rings are used for stem and carrier seals to prevent leakage to the atmosphere. In the open position, the flow is straight through with minimal pressure drop, as long as the porting through the ball is the same size as the inside diameter of the pipe.

Features and Benefits

 True union design on all three ports
 Double O-ring seals on stem for added protection
 Integrally molded ISO mounting pad for both manual and actuated operations
 Blow-out proof, solid mold bottom entry design
 Blocks from left or right union ports, leaving full pressure on the opposite end of valve
 Standard "L" port ball permits flow from common port to either left or right port or to off position
 PTFE seats with elastomeric backing cushions ensure bubble-tight shut-off and a low fixed torque, while at the same time compensating for wear
 Built-in spanner wrench on the handle for valve disassembly and assembly
 All sizes rated for full vacuum service
 Eliminates need for additional valve and "T"
 NSF-61 Certified - Size: ½" - 4"; Material: PVC, EPDM, FKMAvailable Actuators
 Series 79 Pneumatic
 Series 92 & 94 Electric


Options


 Pneumatic and electric actuators and accessories
 Stem extensions
 2" square operating nut or "T" nut
 Locking handles
 Limit switches
 "T" port, Double "L" port


Cross Port Ball Options


 Four different flow patterns through three separate ports are possible because of the crossed flow patterns within the ball
 Changing position of handle changes flow pattern. Handle rotates 360º
