Siemens SQL36E65 Acvatix Rotary Actuator
Configured for motorized butterfly valve control in industrial flow systems, the Siemens SQL36E65 (SQL36E65 Electromotoric Rotary Actuator) provides direct 90-degree mechanical torque execution. Driven by an AC 230 V supply at 50/60 Hz, this actuator processes 3-position (OPEN/STOP/CLOSE) control commands to generate 100 Nm of nominal torque. It features an IP67-rated die-cast aluminum housing with EN ISO 5211 flange mounting interfaces to actuate butterfly valve stems within a 6-second positioning interval for 90-degree movement.

Firmware Flash Compatibility
The Siemens SQL36E65 operates as a standalone electromechanical actuator driven via discrete AC 230 V output relays from host automation controllers, maintaining full functional independence from PLC or DCS firmware flash updates. Control logic execution occurs through hardwired 3-position command channels without dependency on fieldbus communication drivers or real-time network licenses. Internal end switches mechanically interrupt motor drive circuits at travel limits, preserving stroke boundaries across system software upgrades and controller hardware swaps.
Frequently Asked Questions
Q: How does the Siemens SQL36E65 execute travel limit cut-offs during 90-degree rotation?
A: The actuator integrates two internal factory-set end switches rated for AC 250 V, 3 A. Upon reaching the end positions (0 deg and 90 deg), the internal cam trips the switches to cut motor winding power directly without requiring external PLC timing intervention.
Q: Can multiple Siemens SQL36E65 actuators operate in parallel off a single control output channel?
A: Direct parallel operation of multiple SQL36E65 actuators from one output terminal is strictly not permitted. Internal feedback currents between motor windings can cause phase shifts, false switching, and thermal overload.
Q: What mounting standards allow physical adaptation to third-party or Siemens butterfly valves?
A: The base plate conforms to the EN ISO 5211 mounting standard, allowing direct mechanical coupling to Siemens VKF46, VFW41, and VFL41 valve stems as well as compatible industrial butterfly valve bodies.
Field Installation Guidelines
Mount the die-cast aluminum actuator onto the valve mounting flange following EN ISO 5211 alignment tolerances, ensuring the valve stem mates flush with the internal drive sleeve. Secure two M20 cable glands into the housing entries to seal field wiring pathways against moisture ingress and preserve the IP67 enclosure rating. Route AC 230 V power and 3-position control conductors using shielded industrial cables, maintaining single-point chassis ground connections at the panel earth stud. Prior to applying main line power, operate the manual control knob to verify mechanical clearance and unobstructed 90-degree valve rotation.
