The design of this floating ball valve will have extended breakaway torques needed from the actuator. The ball is sealed in the PTFE-lined body with replaceable seat rings – PTFE. It can be assembled with a pneumatic, electric, hydraulic, or electrohydraulic actuator.
Benefits:
Cost-effective solution
Anti-blowout stem
Lining securely locked
Particularly adjusted and trimmed per Durco conventional chlorine washing system
Lined Ball Valves
PTFE lined ball valve is designed for general service applications up to the limits of the ANSI 150 pressure class rating. The ball
shaft in the center can be optionally attached to a pneumatic/electric actuator over an adapter or provided with a manually
engaged lever. The design of this floating ball valve will have extended breakaway torques needed from the actuator. The ball is
sealed in the PTFE-lined body with replaceable seat rings – PTFE. It can be assembled with a pneumatic, electric, hydraulic, or
electro-hydraulic actuator.
