WLD1800R

WLD1800R Series



How It Works

The wld1800 Series liquid drainers contain a float-operated valve. When liquid enters the drainer, the float rises opening the valve which allows liquid to be drained.



Features
  • Stainless steel body
  • All stainless steel internals for longer service life
  • Guided float ensures proper valve seating on every cycle
  • Repairable unit available (wld1800RR)

WLD1800R - Repairable

The WLD1800R Drainer contain a stainless steel float and hardened stainless steel seat and disc to drain out liquids from pressurized piplines, tanks, 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 WLD1800R can be diassembled for service and replacement of internal components.

Product Overview
The WLD1800R Series are used on industrial air and gas applications for drainage of liquid from systems.
Features
• Stainless steel body
• All stainless steel internals for longer service life
• Guided float ensures proper valve seating on every cycle
• Repairable unit available (WLD1800R)
How It Works
The WLD1800 Series liquid drainers contain a float-operated valve. When liquid enters the drainer, the float rises opening the valve which allows liquid to be drained.
Selection / Sizing / Capacities
Determine the capacity (lbs/hr) required at the specified differential pressure. Locate differential pressure on capacity chart; move down column to capacity required. Make sure to select the correct model based on the maximum inlet pressure.

Example:
Required to drain 1,000 lbs/hr at a differential pressure of 200 PSI. The maximum inlet pressure is 250 PSIG.

Select Model:
WLD1822-N  3/4" x 3/4" (non-repairable) or WLD1822R-N  3/4" x 3/4" (repairable); capacity up to 1,200 lbs/hr based on 200 PSI differential pressure.

* PMO based on a liquid with a specific gravity of 1.0. Consult factory for the PMO of a liquid with specific gravity less than 1.0.

Notes:   To obtain capacity with a liquid other than water, multiply water capacity by correction factor.
Dimension and Weights
Installation and Maintenance
The installation should include an in-line strainer. The trap must be level and upright for the float mechanism to operate. Trap must be adequately sized and properly located in the system.

The WLD1800 is non-repairable. The WLD1800R is fully repairable and all working components can be replaced. Repair kits include float, lever & seat assembly, and gaskets. For full maintenance details see Installation and Maintenance Manual.
Sample Specification
The liquid drain trap shall have a guided-float operation with a tamper-proof seal-welded stainless steel body and all stainless steel internals. The unit shall be available with an in-line repairable version. All units to be equipped with FNPT threaded end connections.
