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.


Condensate Sensing Type

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


  • 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.

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.

Drain Valve-Timer Type – Series CTD

The CTD valve series represents the ultimate in valve performance. Decades of experience of valve manufacturing have allowed us to identify the issues commonly associated with drain valves and undertake the necessary improvements required. Today the CTD valve incorporates an ultra-reliable MCU,which features dual control of both drain cycle and drain valve open-time. The oversized orifice design and a specifically designed solenoid operator section allow rapid discharge of dust and particles.


  • All new Mechanical clean function
  • Proven Reliability
  • All digital Electronic Circuit for time control
  • Water proof IP 55 enclosures, ideal for outdoor installations
  • Adjustable Drain and Cycle times
  • CE Approved


The drain is controlled by a timer. The timer module periodically activates the valve. The valves are designed for dirty liquid and handle all types of condensate. These direct acting models have 2.5 mm orifice. The timer has adjustments for both Drain and cycle time. Further there is manual flush button to drain excess condensation if required.


Trident condensate timer drain valves are suitable for all compressed air systems like:

  • Receivers
  • Dryers
  • Heat Exchangers

Micro filters and their manufacturing

Any kind of pneumatic tool perform its best when it is filtered of the various contaminants at regular intervals of time. These contaminants could be dirt, oil and water that come unfiltered through compressed air. The oil and water mostly exist in liquid or vapour forms. Getting rid of these contaminants is a must to prevent any unfavourable effects on your end products. Trident produces coalescing filters that help remove liquid oil and water. The micro filter manufacturing process consists of a filter media made up of boro silicate micro glass fibres. On the other hand, the oil in vapour form is removed using activated carbon filters.

All about Microfiltration Membranes

A wide range of end-users are now using the microfiltration membranes for manifold sets of uses. Unlike several other kinds of equipment for treating water and waste-water, the majority of microfiltration membranes are extremely specific in application. Also, the individual types of products rarely compete with each other. For instance, gaseous filtration or filtration of liquids consisting of high amounts of corrosive chemicals is commonly filtered using PTFE membranes. Also, the microfiltration spiral membranes that are best used for processing dairy products and industrial biotechnological necessities are increasing each day sue to their vast list of utilities. There are a lot many companies that provide you with a lot many solutions engineered to suit your need in the best possible way, one among which is Trident. These solutions not only help you grow your business but also help you stay ahead of the emerging technologies. Some of the key features of micro filters are:-

  • Although at lower effectiveness, particles upto 0.01 microns are filtered
  • Provides you the facility of standard fitment of automatic drain valve
  • A very low pressure drop of 1 PSI for dry media and 2-3 for wet media with 10-20 wt oil
  • Provides you with a status indicator
  • Offers you a maximum oil carry over value of 0.008 ppm w/w
  • Different grades of coalesce for manifold applications

Types and their operation

Coalescers and interceptors are two further types of typical 0.01 micron filters of this series. These coalescing filters are fine strands of Borosilicate glass fibre that can coalesce the finest of oil and water aerosils. These fine droplets of oil and water further coalesce to form a large droplet that falls down due to the gravity. On the other hand, the interceptors help in removing particles. These filters have a very low pressure drop. They are used either after the filtration process in the desiccant dryer or for any general use for fusal instrument protectors.

All about Trident Micro filters

Trident has thrived in the business of catering to various requirements of the customers by offering them with the best of micro filters. These requirements range from the various commercial to the various residential sectors for the filtration of oil and water. There are many varieties available in Trident’s wide spectrum of filters that are suitable for all compressed air systems namely the sensitive and CNC m/c, painting systems, instruments, packaging etc. These filters feature accurate performance, superior quality and resistance to wear and tear which makes them highly demanded in the market. Their sound infrastructure in micro filter manufacturing has made this possible.
