The ECV-250B-4X Electronic Control Valve is a computer-controlled proportional valve which directly accepts a 4-20 mA or 1-5V DC control signal. The ECV performs better, costs less to install and less to operate than competitive valves. It is ideal for accurate control of liquid and gas flow.
The ECV is field programmable. There is no need to stock an expensive inventory of actuators for normally open, normally closed, full range or split range operation. The ECV can be set to fail open or closed on loss of the control signal.
The ECV has no backlash and no hysteresis. This greatly simplifies control programs. The valve is opened and closed by a zero-backlash screw mechanism. A step motor is directly connected to the valve without gears. The valve can also be operated manually.
An adaptive digital filter eliminates dithering of the valve due to noisy control signals. This digital filter can be disabled via a switch on the circuit board.
The valve design features a long-life rotary stem seal. Rotary seals are more durable and require less maintenance than reciprocating stem seals used in pneumatic valves. This seal does not cause the unwanted stick-slip action of pneumatic valves.The compact size of the ECV makes it easier to handle, and allows it to be installed in smaller spaces. The ECV is about half the size of a pneumatic valve.
The ECV is easy to set up. The installer simply sets the dip switch. Setup typically takes less than 5 minutes.
An ECV installation costs less than a comparable pneumatic control valve system. There is no need for compressed air, filters, regulators, I-P converters, or pneumatic air lines. Simply connect the ECV to the control signal and the power supply.
The reliable, low-maintenance design and heavy-duty construction reduce costly downtime. Electronics are protected by a watertight, NEMA 4X rated ABS enclosure.
The ECV-250B-4X has a brass valve body with Type 303 stainless steel trim. It has 1/2 inch pipe fittings with a 1/4 inch port size and a Cv of 0.6
