Valworx 567657C electric actuated lead free brass ball valve is used to control the flow of water, air, oil, and other media compatible with the materials of construction. Ideal where lead free and NSF construction are required for potable drinking water as well as other industrial applications. 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 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. Valve can be set to fail closed, in-place or open with loss of control signal. 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. Rugged unique integral motor/housing design 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.
High temperature valve mounting kit available for extended temperature range or wall mounting applications.
