FAQ

The T.VIS A-15 is a control and feedback unit. It provides a clear visual indication of the valve's position (open/closed) via LEDs, sends an electronic PNP signal back to the PLC or control system, and can house solenoid valves to control the air supply to the actuator.

HNBR (Hydrogenated Nitrile Butadiene Rubber) has good resistance to oils, chemicals, and moderate heat, typically up to 150 deg Celsius (302 deg Fahrenheit). However, its suitability depends on the specific process medium and temperature. For steam or higher temperature applications, alternative seals like EPDM or FKM might be required.

This type of pneumatic actuator is typically either single-acting (spring-return) or double-acting and does not include a standard manual override handle. In case of air failure, a spring-return actuator will automatically move to its pre-defined safe position (fail-open or fail-closed). Manual operation would require external tools to manipulate the valve stem.
