Solberg DSP Series Pneumatic Drain Systems

Request Product Quote


The Pneumatic Drain System allows Solberg Liquid Separator units to be drained without stopping the process or any loss of vacuum. The liquid removed by the liquid separator flows under gravity into the drain pot. When the high level sensor detects the liquid, the drain pot is isolated from the liquid separator by the upper pneumatic ball valve. The bleed in valve then opens along with the bottom drain valve allowing the liquid to drain to atmosphere by compressed air. When the lower level sensor triggers, the bleed in valve closes along with the bottom drain valve and the upper pneumatic ball valve opens to allow the process to repeat.
