WLD1800 Guided Float Liquid Drainers

The WLD1800 Drainer contain a stainless steel float and hardened stainless steel seat and disc to drain out liquids from pressurized pipelines, tank, and vessels without the loss of the pressured gas. Available in either a repairable (WLD1800R) or a non-repairable (WLD1800) version. The all stainless steel construction allows them to be used in extremely corrosive environments. The WLD1800 is seal welded and therefore non-repairable.

  • Stainless steel body
  • All stainless steel internals for longer service life
  • Guided float ensures proper valve seating on every cycle
  • Repairable unit available (WLD1800R)

The WLD1800 Guided Float Liquid Drainers contain a float-operated valve. When liquid enters the drainer, the float rises opening the valve which allows liquid to be drained.
