ISO-Top mounting flange according to ISO 5211
Suitable for mounting the hand lever as well as stem extensions. In particular, the automation of ball valves using pneumatic or electric actuators of all brands with compatible connections according to ISO 5211, as well as for accessories such as limit switches, etc., makes ball valves with ISO-Top extremely versatile in application.
Installation length
Due to their compact design, these valves are ideally suited for use in confined spaces.
Furthermore, they are designed in such a way that the ball does not protrude beyond the body even in the closed position, allowing the valves to be installed or removed in both the open and closed states.
Antistatic Function
The ball valves in this series are equipped as standard with antistatic stems, which establish a permanent connection between the ball and the stem, as well as between the stem and the valve body.
As a result, any potential electrical charges are safely dissipated through the body. This safety feature is becoming increasingly important, especially for automated ball valves. The implementation of this function may vary depending on the specific model.
