Valworx 540908A electric actuated PVC butterfly valves are typically used for control of water and liquid media compatible with the materials of construction. Ideal where NSF certified construction is required for potable drinking water as well as other industrial applications.
The EPS- Electronic Positioner 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 proDiscional 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 (4-20mA input). 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.
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. Typical applications include industrial/process piping, pulp and paper, food processing, water treatment and irrigation.
Modbus control is available as a factory-installed option. Click on the Accessories tab for details.
PVC butterfly valves should never be used for compressed gas applications.
