4" High Performance Butterfly Valve, Wafer, RPTFE, 110 VAC, EPS Positioner

Valworx 569204A high performance stainless steel butterfly valve for control of air, oil and other media compatible with the materials of construction. Wafer style valve sandwich mounts between customer supplied ANSI /ASME Class 150 and other international standard flanges and gaskets. The EPS- Electronic Positioning System provides an accurate valve positioning function whereby the movement of the actuator is controlled by a 4-20mA input control signal. Any change in the control input signal results in a corresponding and proportional change in the position of the ball. The internal microprocessor and closed loop feedback system continuously monitors and maintains accurate valve position. The valve will remain in the last known position with loss of electric power.

The positioning module is self-calibrating and fully potted to help protect the electronics against vibration and moisture. Valve position can be monitored with onboard analog output signal.

The valve is direct mounted to the actuator using the international standard ISO5211 mounting pad. Actuator has a rugged unique integral motor/housing design which provides higher torque in a very small package.

Actuators are tested to rigorous UL and CSA standards and certified by CSA. Anti-condensation heater is standard and will help protect actuator against damage caused by condensation.

Modbus control is available as a factory-installed option. Click on the Accessories tab for details.
