Product Overview
WLD600-Series have Cast Steel Bodies. The WLD601-Series have Stainless Steel Bodies. Used for draining liquids from Tanks, Vessels, and piping systems containing pressurized Air or other gases.
Features
• All stainless steel internals for long service life
• Body & cover available in Carbon Steel or 316 SS
• Rugged construction designed for heavy industrial applications
• In-line repairable
How It Works
The WLD600/WLD601 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 2,000 lbs/hr at a differential pressure of 300 PSI. The maximum inlet pressure is 325 PSIG.

Select Model:
WLD600-450-14-N, 1” NPT, capacity up to 2,250 lbs/hr based on 300 PSI differential pressure

Example Models: WLD600-450-14-SW = 1” Socket Weld, WLD600-450-14-F600 = 1” 600# FLG
Connections: (N=NPT, SW=Socket Weld, F150=150# FLG, F300=300# FLG, F600=600# FLG)

Capacity in lbs/hr is based on differential pressure across the drainer. Select a model with an equal or higher PMO (max. operating pressure) than the maximum inlet pressure to the drainer. If the pressure to the drainer exceeds the PMO, the drainer may not open. If discharging to atmosphere, the differential pressure is equal to the inlet pressure.

Installation and Maintenance
The installation should include isolation valves to facilitate maintenance and 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. Installation may require an equalizing or balancing line connected from top of drainer body to the above piping, for proper drainage.

All working components can be replaced with the drain trap remaining in the pipeline. Repair kits include float, valve seat & disc and gaskets. For full maintenance details see Installation and Maintenance Manual.
Sample Specification
The liquid drain trap shall be float operated with a cast steel body (or stainless steel body for WLD601) and all stainless steel internals. The unit shall be in-line repairable and equipped with a FNPT threaded connection for the use of a balance line.
