Type 5824 Electric Actuator without fail-safe action - 1

DATA SHEET T 5824 EN Type 5824 Electric Actuator without fail-safe action Type 5825 Electric Actuator with fail-safe action Application Electric actuators designed for valves used in heating, ventilation and air-conditioning systems as well as in process engineering and industrial energy transfer systems. Special features The linear actuators are particularly suitable for attachment to SAMSON Types 3260, 3222, 3226, 3213, 3214 and V2001 Valves. In addition, they can be used as additional electric actuators on self-operated differential pressure and flow regulators. • Type 5824 Actuator without fail-safe action and Type 5825 with fail-safe action • Motor switched off by torque-dependent limit contacts • Type 5824 with manual override (handwheel) • No maintenance • Testing according to DIN EN 14597 - The Type 5825 Electric Actuator with fail-safe action "actuator stem extends" is tested by the German technical surveillance association TUV according to DIN EN 14597 in combination with different SAMSON valves. The registration number is available on request. Versions • Three-step version - Synchronous motor with maintenance-free gearing • Digital positioner - Stepper motor with maintenance-free gearing - Adjustment of the direction of action at the actuator - Start-up at the actuator - Settings made using the TROVIS-VIEW software Options • Faster motor - Double transit time possible (three-step version) • Limit contacts - Two adjustable mechanical changeover switches • Resistance transmitters - One resistance transmitter with range from 0 to 1000 Q Fig. 1: Type 5824-10 Electric Actuator Table 1: Actuator versions SAMSON AKTIENGESELLSCHAFT ■ WeismullerstraBe 3 ■ 60314 Frankfurt am Main, Germany Phone: +49 69 4009-0 ■ Fax: +49 69 4009-1507 ■ samson@samsongroup.com ■ www.samsongroup.com

Type 5824 Electric Actuator without fail-safe action - 2

Design and principle of operation Refer to Fig. 2 The actuators are mounted directly onto valves with force-locking connection. When the actuator stem extends, the actuator piston pushes against the valve's plug stem. When the actuator stem retracts, the plug stem is supported by a spring in the valve. –– Actuator stem extends Upon voltage supply failure, the actuator stem extends. –– Actuator stem retracts Upon voltage supply failure, the actuator stem retracts. –– Version with faster motor (three-step version) The Types 5824-13/-23/-33 and Types 5825-13/-23/33 are equipped with a faster...

The digital positioner settings can be changed in the TROVIS-VIEW software. Table 2: TROVIS-VIEWsettings Table 3: Replacement of old actuators with new actuators (valve remains unchanged) 1 Double stroking speed There is no replacement for Types 582x-1,582x-2, 582x-3 and 5822-4 Actuators. Valve and actuator must be replaced. In this case, the actuator must be selected to fit the new valve.

Table 4: Technical data • Three-step version Actuators with 6 mm travel can also be used for valves with 7.5 mm travel (45 s transit time, 22.5 s with faster motors) The safety spring pulls actuator stem to the retracted end position; the valve operated by the valve spring. Manual override using 4 mm Allen key (after removing the cover); actuator always returns to fail-safe position after release Special version The permissible medium temperature depends on the valve on which the electric actuator is mounted. The limits in the valve documentation apply. The degree of protection IP 54 can...

Adjustable (default settings in bold print) The safety spring pulls actuator stem to the retracted end position; the valve operated by the valve spring. Manual override using 4 mm Allen key (after removing the cover); actuator always returns to fail-safe position after release With a fast stroking speed and 24 V DC power supply, make sure the voltage does not fall below the specified value. With standard speed level The permissible medium temperature depends...
