Actuation and Performance
  1. The pneumatic actuator is available in double-acting and spring-return configurations, with spring-return models ensuring fail-safe reset to a safe position in the event of air supply loss.
  2. Pneumatic actuation delivers reliable, low-torque operation, enabling precise control even under high-temperature and high-pressure conditions.
  3. The triple eccentric metal seal design minimizes wear and ensures long-term, tight shut-off, making it ideal for demanding process systems where reliability is critical.
