VALPES VTX ATEX Electric Quarter-Turn Actuator

The VALPES VTX ATEX is an electric quarter-turn actuator designed for butterfly valves, ball valves, and plug valves in hazardous (explosive) atmospheres. It covers torque ranges of 600 and 1000 Nm, with a standard rotation angle of 90° and optional 180° or 270° versions available on request.

Technical Specifications

  • Power supply: 230 V AC 50 Hz or 400 V 3-phase 50 Hz.
  • Control: 3-point modulating.
  • Power: 250 W.
  • 90° operating time: 38 s.
  • Duty cycle: S4 50% per IEC34.
  • Ambient temperature: -20 to +63 °C.
  • Ingress protection: IP68, 5 m / 72 h.
  • Valve interface: ISO 5211 F10/F12, star drive 36 mm.

ATEX Marking and Installation

Marking: II 2 G D Ex db IIB T5 Gb / Ex tb IIIC T90°C Db. Certified under LCIE 06 ATEX 6006X and IECEx LCIE 15.0074X. Suitable for zones 1 / 2 (gases) and 21 / 22 (dusts). Use ATEX-rated metal cable glands matching actuator category.

Construction and Operation

Aluminum housing with C4 coating; marine version C5-M available. Features include manual override, visual position indicator, anti-condensation heater, adjustable mechanical stops (0°/90°), and mechanical torque limiter. Unlike VRX/VSX, options BBPR, POSI, Modbus-RTU, Bluetooth are not available for VTX.

Applications

Used in chemical plants, petrochemicals, fuel gas systems, storage tanks, marine environments, and industrial lines requiring Ex protection and torque up to 1000 Nm. Media compatibility is determined by the valve; VTX selection is based on torque, Ex zone, voltage, 90° time, and installation environment.

FAQ

When to select VTX over VSX?
When the valve requires torque above 300 Nm and F10/F12 interface.

What is checked during maintenance?
Ex cable glands, grounding, IP68 sealing, mechanical stops, manual override, torque limiter, and torque matching with the valve.

Protection (Options)
