BELIMO 3 WAY VALVE- AUTOMATIC DIVERTER VALVE - 1" NPT 240VAC

The Zone Valve combines the proven performance of a synchronous motor technology with “enhanced motion” gear action which reduces motor wear while providing smooth, quiet (no water hammer), and constant close off. The crafted brass forged body is rated at 300 psi, and the high temperature paddle design assures years of trouble free operation. Precision formed components and an exclusive spring calibration process ensure uniform spring return and long valve life.

Features:

  • Compact in design, fits inside fin tube casing and fan coils
  • Wide service range, rated from 32°F to 212°F medium with up to a 50% glycol mix
  • Up to 75 psi DP close off

This valve is typically used on fan coil units, baseboards or other hydronic applications where fail safe operation on 2-wire control is required. This valve is suitable for use in a hydronic system with variable or constant flow. This valve is designed to fit in compact areas where on/off or control is required using 24 VAC or 120 VAC
