The world of Trident auto-drain valves In the progression of automatic drain valve manufacturing technology, Trident’s condensate sensing type automatic drain valves are the newest. Quintessentially useful and reliable, these valves sense the condensate level for activation instead of working through the cycle timer. The capacitance type of sensor, which can work on all types of condensates like water, water plus oil, water plus oil plus dust and more as such, detects the gradual rise of the level as the condensate starts collecting in the drain valve. The controller on the other hand signal the valve to open when the condensate reach the upper level. The condensate now drains slowly reaching the lower level. The controller thereby switches off the valve hence stopping the draining. This controller, with the help of indications from 3 LED displays, responsibly browses for any failures in the valve and take corrective actions accordingly; this it does very routinely which keeps a check on the health of the system. A Test/Manual override button also facilitates the process. This operational method of these valves negate any loss of compressed air hence saving a vast amount of energy. The manual drains of the equipment can be easily replaced by fitting the Trident drain valves on them. What all it has to offer? Trident offers a spectrum of auto drain valves to its clients that are very effective in the purification of air by removal of pollutants. For instance, automatic drain valves, electronic drain valves, air drain valves etc.
