FLOW CONTROL PRODUCTS

Liquid Drain Trap

Liquid drain trap is used to remove this water continuously and automatically, while preventing the escape of compressed air. The balance pipe allows air which may enter the trap to escape back to the receiver.

Features

  1. Improve operational efficiency
  2. Precise control

INSTALLATION

Horizontal installation with flow from left to right. Liquid drain trap should be installed below the drain point of the equipment with the flow direction as indicated by the arrow on the trap. It is recommended that an equalizer line be fitted as shown in the installation manual for this product. The word ‘TOP’ on the nameplate indicates the top side of the trap.

MAINTENANCE

Liquid drain trap has to be removed from the line for maintenance. It is recommended that the trap be opened periodically and the internals inspected for wear, damage, and dirt. All worn or damaged parts should be replaced with new spares. A new internal kit comprising of the valve pin, valve seat, bracket and lever should be replaced as a set. The bucket vent hole should be cleaned.
