The Siemens SQN75 series consists of reversible electromotoric actuators specifically designed for the control of gas and air dampers on burners of small to medium capacity. They are distinguished from the SQN70/71 models by their completely black housing (both the gear train and the cover) and are often used as direct replacements for older Conectron or Berger actuators.
1. Key Performance Specifications| Feature | Specification |
| Rotation Direction | Clockwise (CW) |
| Nominal Torque | $1.5\text{ Nm}$ to $2.5\text{ Nm}$ (depending on the model) |
| Holding Torque | $0.7\text{ Nm}$ to $1.3\text{ Nm}$ |
| Running Time | $4\text{ s}$ to $30\text{ s}$ for $90^\circ$ (at $50\text{ Hz}$) |
| Mains Voltage | AC $230\text{V}$ (suffix A21) or AC $110\text{V}$ (suffix A11) |
| Power Consumption | Approx. $6\text{ VA}$ |
| Protection Class | IP40 (upgradable to IP54 with specific cable entries) |
| Angular Adjustment | Max $160^\circ$ (Factory setting $90^\circ$) |
The SQN75 series uses a modular "Circuit Diagram" numbering system. The middle digits (e.g., .294 or .424) define the running time, torque, and internal relay/switch count.

-
Housing: Made of impact-proof and heat-resistant plastic. The black color indicates it is part of the SQN74/SQN75 branch of the family.
-
Motor: Reversible and locking-proof synchronous motor.
-
Geartrain: Maintenance-free with a manual disengagement mechanism (Pin K). Pressing this allows the shaft to be rotated by hand for commissioning.
-
Adjustment: Switching points are set via color-coded adjustable cams. Some models include fine-adjustment screws that can be turned with a standard screwdriver.
-
Potentiometer: Special versions are "ready-prepared" for fitting a potentiometer for position feedback ($1000\ \Omega$ or $5000\ \Omega$).
While both are black-housed actuators:
-
SQN74: Rotates Counter-clockwise (CCW).
-
SQN75: Rotates Clockwise (CW).
Installing the wrong rotation direction will cause the burner to fail its pre-ignition safety check.

general description
skp25. Xxxux electro???hydraulic actuators are used in combination with vgxxx. Xxxu gas valve bodies to provide slow opening, fast closing safety shut off and, depending on model gas pressure regulation and air/gas ratio control for industrial and commercial burner applications. Since safety shut off, constant pressure regulation or air/gas ratio control can be performed by a single valve, fewer gas train components and fittings are required to assemble a gas train. This significantly reduces both the size and weight of the gas train. The total pressure drop across the gas train arrangement is reduced, allowing for the use of smaller diameter gas trains in most applications. The compact skpx5. Xxxux actuator opens slowly when powered and closes immediately upon power interruption. The modular design allows the skpx5. Xxxux to be used in combination with all vgxxx. Xxxu gas valves bodies from ½" to 6" sizes. The actuator can easily be mounted on the square flange of any vgxxx. Xxxu valve with four pre???mounted screws. No gaskets or seals are required when mounting the actuator. A visible position indicator on the front of the actuator displays the entire stroke of the valve. A light indicates when the actuator is powered.
skp25. Xxxux the skp25. Xxxux controls the burner manifold gas pressure according to a fixed setpoint. The skp25. Xxxux can also be applied as a 1:1 air/gas proportionator or zero governor.
features
skp25. Xxxux • ul listed, fm approved, csa certified, iri approval, and iso 9001 certified. European, australian and japanese approved versions available. • proof of closure with over travel (poc) option. • optional nema 4 protection. • visual position indication. • "power on" indication light. • quick connect wiring terminals. • optional adjustable auxiliary switch. • modular design with 360° actuator rotation for easy field wiring and installation. •low (10 va typical), power consumption.
skp25. Xxxux • safety shut off function and pressure regulating function in one compact unit. • applicable as 1:1 air/gas proportionator or zero governor. • accurate pressure control characteristics, and zero offset (drop). • integral regulation leak limiter. • excellent tracking characteristic.
