VALPES LT Low Temperature Electric Quarter-Turn Actuator

The VALPES LT is an electric quarter-turn actuator designed for ball valves, butterfly valves, and plug valves operating in low ambient temperatures. Torque range: 25–300 Nm. Features include an aluminum housing, C4 coating, and standard 90° rotation. Optional 180° or 270° rotation available.

Technical Specifications

  • Operating temperature: -50 to +70 °C.
  • POSI version: -40 to +70 °C.
  • Ingress protection: IP68, 5 m / 72 h, optional IP68, 10 m / 72 h.
  • Duty cycle: S4 50% (IEC34).
  • Power supply: 100–240 V AC 50/60 Hz / 100–350 V DC or 15–30 V AC 50/60 Hz / 12–48 V DC.
  • Integrated 30 W heater to prevent condensation and ice formation inside the housing.

Connection and Control

Valve mounting per ISO 5211. For 25–75 Nm: F05/F07 star 17. For 100–300 Nm: F07/F10 star 22. Supports on-off or 3-point control. Includes manual override, visual position indicator, mechanical stops (0°/90°), electronic torque limiter, fault relay, and RS485 connectivity.

Automation Options

Available with POSI for analog control 4–20 mA or 0–10 V, 3 positions function, Modbus-RTU, and Bluetooth / AXMART. Marine version with C5-M coating available.

Applications

Suitable for cold mechanical rooms, outdoor water networks, seawater, air, auxiliary gases, refrigeration units, frost-prone installations, and industrial skids. Media compatibility is determined by the valve. LT selection is based on torque, ambient temperature, voltage, IP rating, and control signal.

FAQ

When to select LT over VR or VS?
When ambient temperature is below the standard limits of conventional versions.

What is checked during maintenance?
Cable glands, IP sealing, 30 W heater, limit switches, mechanical stops, manual override, fault relay, and correct torque matching with the valve.
