Condensate Sensing Drain Valve – Series LDV
sensing_valve
Trident's condensate sensing type automatic drain valves is the latest advancement in drain valve technology. Instead of operating through cycle timer, these valves sense the condensate level for activation, ensuring absolutely NO LOSS of compressed air and hence enormous ENERGY SAVING Trident condensate sensing type drain valves are highly efficient and reliable. These drain valves can be fitted directly on the equipment simply by replacing the manual drains.
Features
Latest in drain valve technology.
Electronically senses condensate and activates valve.
No air loss and is extremely economical to operate.
Status indicator.
IP 65 protection.
Test button for quick check.
No noise as air is not discharged.
Capable of draining oily condensate.
Operations
Condensate collects in the drain valve and the level slowly rises which is detected by the sensor. When the condensate reaches upper level the controller signals the valve to open. The condensate now drains. When the condensate level reaches low level the controller switches off valve and stops the draining.
The controller routinely checks for health of the system and can detect probe or valve failure and take action. There are 3 LED displays which indicate all these. There is also Test/ Manual override button. The condensate level sensor is of capacitance type. This makes it work on all types of condensates e.g. water, water+oil, water+oil+dust etc.
If the condensate is not discharged due to valve failure then the condensate level will not reach lower limit. The controller energises the solenoid coil for 8 secs. and waits for 2 mins. It repeats the timed cycle of 8 secs. ON and 2 mins. OFF, 4 times. If condensate level does not reach the low limit then the controller activates the alarm mode and alarm mode LED glows. In the alarm mode the controller works on a timed cycle. The controller automatically reverts to normal mode when the problem clears.
Application
Trident condensate sensing drain valves are suitable for all compressed air systems like :
Air receivers
Separators
Air dryers
Filters
Inter and after coolers.
