It removes the unwanted impurities from water and lubricants from air compressor systems. It is a type of valve whose working is based on a sensor. These sensors are placed inside a reservoir. These sensors control the auto drainer valve. The drain valve opens when the condensate level increase and closes when the condensate level decreases. Therefore these valves maintain the balance. We are an importer and supplier of auto drainer valves from Mumbai. We supply in bulk.
