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.
Required to drain 3,000 lbs/hr at a differential pressure of 5 PSI. The maximum inlet pressure is 30 PSIG.Select Model:
WLD1916-030, 11/2”, capacity up to 4,710 lbs/hr based on 5 PSI differential pressure.
