Asahi Multiport Ball Valves

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"
