PRCA-S2-T Rotary Actuator, 160 Nm, AC / DC 24...230 V

• Nominal torque 160 Nm 
• Nominal voltage AC 24...240 V / DC 24...125 V
• Control Open-close, 3-point
• with 2 integrated auxiliary switches

Fields of application

The actuator is particularly suitable for utilisation in outdoor applications and is protected against the following weather conditions:

• UV radiation
• dirt / dust
• rain / snow
• Humidity

Parameterisable actuators

The factory settings cover the most common applications. Single parameters can be modified with the ZTH EU or the Belimo Assistant App. The Belimo Assistant App simplifies commissioning and parameterisation via Near Field Communication (NFC). Moreover, it provides a variety of diagnostic options.

Simple direct mounting

Simple direct mounting on the butterfly valve. The mounting orientation in relation to the butterfly valve can be selected in 90° (angle) increments.

Manual override

The valve can be manually operated using a hand crank. Unlocking is carried out manually by removing the hand crank.

Internal heating

An internal heater prevents condensation buildup. Thanks to the integrated temperature and humidity sensor the built-in heater automatically switches on.

High functional reliability

The actuator is overload protected, requires no limit switches and automatically stops when the end stop is reached.

Combination valve/actuator

For valves with the following mechanical specifications in accordance with ISO 5211 F07:

• Square stem head SW = 17 mm for form-fit coupling of the rotary actuator.
• Hole circle d = 70 mm

Flexible signalization

The actuator has one auxiliary switch with a fixed setting (10°) and one adjustable auxiliary switch (0...90°).
