Valworx 566558A compact electric actuated 2-piece stainless steel ball valve is used to control the flow of water, air, oil, and other media compatible with the materials of construction. 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.
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.
High temperature valve mounting kit available for extended temperature range or wall mounting applications.
