Maintenance free live loaded double sealing stem packing ensures high cycles life and positive sealing.
Blow-out Proof Stem
ISO5211 Mounting Pad Allows for mounting of actuator
Spring Loaded Seat Design

The tunnion design high performance ball valves use the upper & lower supports to retain the ball under pressure. It allows the valve to be installed in either direction. This valve can be used in applications with reversing flow. Another features of tunnion design is that it allows the ball valve to act as a true union. This Allows downstream piping to be disconnected under full upstream, pressure (Provide the downstream piping is drained of liquid and that the valve is indeed closed to upstream piping). The tunnion on a two way ball valve supports the ball in much the same way as the stem does on top.
