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.
