SIPOS SEVEN 2SA7 multi-turn electric actuator, 9–1000 Nm, integrated frequency converter

SIPOS SEVEN 2SA7 is the basic series of multi-turn electric actuators for gate valves and globe valves. The actuator has an integrated frequency converter; output speed is set electronically in the range of 5–160 rpm.

The series is available as 2SA70 (class A), 2SA73 (class B) and 2SA75 (class C) with ECOTRON or PROFITRON electronics. Soft start and soft stop reduce water hammer and valve wear, starting current is below rated current, and full torque is maintained with mains voltage drops of up to −30 %.

Key features:

• Integrated frequency converter, electronic speed setting 5–160 rpm
• Soft start and stop — less water hammer and valve wear
• Full torque at mains voltage drop down to −30 %, starting current below rated
• ECOTRON or PROFITRON electronics, classes A/B/C
• Handwheel, remote-mounted electronics option, ISO/DIN valve interface

Specifications:

• Torque: 9–1000 Nm; up to 4000 Nm per series documentation; up to 50,000 Nm with gearbox
• Speed: 5–160 rpm, electronic setting
• Versions: 2SA70 class A, 2SA73 class B, 2SA75 class C
• Electronics: ECOTRON or PROFITRON
• Enclosure protection: IP68
• Corrosion category: C5
• Ambient temperature: −20…+70 °C
• Communication: discrete/analog signals, PROFIBUS, Modbus, HART, PROFINET
• Valve interface: ISO/DIN

Application: Automation of gate valves and globe valves in pipelines for open/close and positioning duty.

Before ordering: Before ordering, specify the required torque, speed, duty class, electronics type and communication protocol.
