Liquid Changeover

LR : LR-SF/LA – Liquid Changeover Regulator


  • Liquid Auto Changer
  • Easy visible status indicators
  • CE certified

Features

When there are two cylinder lines, changeover from line-A to line-B for replacement is always required. Liquid Changeover LR switches active line from line-A to line-B automatically by detecting pressure

COMPACT SIZE

Space-saving compact size allows more freedom for installation.

SNAP REVERSE STRUCTURE

Red arrows indicates which line is in use. changeover activation status can be checked easily by color indicator.

DOUBLE INDICATORS

LR functions with “Snap Reverse Structure” to achieve dust-proof and rain-proof construction. The simplest and most reliable form of liquid automatic changer realizing highly accurate and instantaneous changeover operation.

Attenttion

  • Explosion-proof Signal Transmitter Switch (Optional)
    With Signal Transmitter Switch, the actuation of LR could be verified under remote monitor through a telephone line
    Control circuit : 220V
  • LPG consumption should be lower than the LR standard capacity indicated above
  • If the LR inlet pressure requirement could not be adapted, it might be necessary to change the LPG composition
