HW Limit Switch Box Series

Brand: Soldo Controls - by Rotork
Request Information
Control unit embedded into a limit switch box. 

The HW series provides, not only a visual and electrical remote position feedback, but, using a solenoid valve integrated into the housing, can also control an automated valve.

Available in polyester powder coated aluminum, with different lid choices, and with a wide selection of solenoid valves, from the standards 3/2 way to a 5/3 way with special pneumatic design.

The Soldo control unit, is covering from industrial automation to food and beverage, from chemical to naval industries.

It can also meet the requirements of a simple limit switch box, by removing the control side, providing a large inner volume able to host up to 6 switches and spare pass through terminals.
Features
  • Twin shaft design, ensuring a complete sealed device. The shaft is split in two parts, each fitted and sealed into the body and cover for the best weather insulation even during opening operation
  • Up to three cable entries, either metrics or imperial
  • Enhanced corrosion resistance thanks to the thick polyester powder coating on aluminum housings
  • 3/2, 5/2 or 5/3 way solenoid valve for pneumatic control
  • Compact solution embedding the solenoid valve into the limit switch box
  • Easy wiring through the terminal PCB board
  • NOVA V3™ switch option ensures extreme durability and high power switching capabilities
  • 4-20 mA position transmitter options
  • ASI communication protocol board
  • Integrated Namur mounting kit
  • Captive bolts on the screwed lid
