The Type 2780 HVAC pneumatic linear actuator, featuring diaphragm-type mechanism and die-cast aluminum casing, is engineered for HVAC systems and mechanical applications. With internal compression springs, it seamlessly integrates with SAMSON Type 3213 and Type 3222 Globe Valves, as well as Type 3226 and Type 3260 Three-way Valves. Its design facilitates easy reversal of actuator action and allows direct attachment of a positioner, eliminating the need for external piping regardless of operational direction.

The Type 5824 and 5825 HVAC electric linear actuators cater to heating, ventilation, and air-conditioning systems, ideal for SAMSON valves integration and as supplementary actuators for pressure and flow regulators. Featuring synchronous motor and maintenance-free gear or digital positioner with stepper motor, these actuators offer torque-dependent limit switches for motor shutdown, manual override for Type 5824, adjustable positioning speeds, LED indication of operating status and errors, and blocking protection. The three-step version provides options like faster motor, adjustable limit contacts, and resistance transmitter, with configuration and diagnostics facilitated through TROVIS-VIEW software, enabling direct connection for monitoring via PC or memory pen.
