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. The cherry on the cake that Trident provides is the exclusive feature of custom-made auto drain valves as per the specifications desired by their client.

The LDV Series

Trident’s condensate sensing type automatic drain valve is the latest advancement in drain valve technology. These valves sense the condensate level for activation, ensuring absolutely no loss of compressed air and hence results in enormous energy saving. Trident condensate sensing type drain valves are highly efficient and reliable. Fault tolerant system is switching over into timer mode automatically while LDV fails to operate due to sensor failure. Timing cycle is every 2 mins for a period of 2 seconds.


  • The electronic level control ensures proper draining of condensate and avoids unnecessary loss of air.
  • All the functions of the valve are accurately indicated by the LED display.
  • Test switch (or) manual drain allows function test at anytime.
  • Intelligent Controller detects valve, probe failure and acts accordingly.
  • Noise free, as air is not discharged..
  • Inbuilt fault tolerant system ensures continues operation of drain valves.


  • Zero Air Loss
  • Design Patented
  • Noise Free
  • Fault tolerant system

Why Trident?

The chief automatic drain valve manufacturers, suppliers and exporters of electronic auto drain valves include the name of Trident. Their products are used in a variety of industries. Although competitively priced, these valves are of high quality; having undergone several quality tests prior to their delivery to the customers for regular and efficient draining of oil and moisture from compressed air systems. The complete process of quality testing is done under the surveillance of expert professionals. Trident offers auto drain valve in both regular and full bore types.
