WLD1400

WLD1400 Series





How It Works

The WLD1400 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
  • All stainless steel internals
  • Hardened valve seat for longer service life
  • Ductile Iron body
  • In-line repairable

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.

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.

Example:
Required to drain 3,500 lbs/hr at a differential pressure of 2 PSI. The maximum inlet pressure is 15 PSIG.

Select Model:

WLD1416-N-065, 11/2”, capacity up to 4,300 lbs/hr based on 2 PSI differential pressure. PMO = 65 PSI

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 ductile iron body, all stainless steel internals and a hardened valve seat. The unit shall be in-line repairable and equipped with a FNPT threaded connection for the use of a balance line.
