Drain Valve - Timing Type

Drain Valve - Timing Type
 

EDV series valves are timer based automatic drain valves. The valves are specially designed for dirty condensate. The controller is designed for dirty and harsh outdoor conditions. These drain valves are upto 1" orifice and 70 Kg/cm2(g) pressure.

Operation

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. There are 3 basic models. The direct acting models have 1.3 mm orifice. The diaphragm type has 8mm orifice and external pilot assisted piston valve has orifice upto 24mm.

Salient Features

Proven Reliability    All digital Electronic Circutry for time control    Water proof IP 55 enclosures, ideal for outdoor installations    A wide network for after-sales service   Available in 64 models to suit all applications    Optional: Explosion proof enclosure for hazardous areas   Pressure upto 70 kg/cm2(g).

Application

Trident condensate timer drain valves are suitable for all compressed air systems like :    Receivers   Dryers    Heat Exchangers    Circuit Breakers    Locomotives   Earth moving equipment
