Class 600, Regular / Full port, Flanged / Butt Weld Ends, Floating design / Trunion Mounted design

Key Features
  • Maintenance-free live-loaded double sealing stem packing ensures high cycles life and positive sealing.
  • ISO 5211 Mounting Pad Allows for mounting of actuator.
  • Blow-Out Proof Stem.

A floating ball design offers efficient sealing with simple construction. As the name indicates, the ball has some freedom to move along the axis of the pipeline, which offers efficient downstream sealing. When line pressure is applied to the closed ball, it moves slightly (or floats) downstream to maintain contact with the downstream seat where primary sealing occurs. A quarter-turn motion from full open to full close ensures quick open-close action, an inherent advantage for automatic remote control applications. The floating ball valve offers effective bi-directional sealing.

Trunion-mounted design offers precise locational accuracy for the ball within the upstream and downstream seat, which ensures leak-tight sealing with lower operative torques. The sealing takes place by allowing the seats to move towards the ball. This design of ball valves can hold very high pressures.
