Electric Actuated Butterfly Valve 2-1/2" Lug,NBR,24 VDC, EPS Positioner

Valworx 567447A electric actuated soft seated butterfly valve is used to control the flow of air, oil and other media compatible with the materials of construction. Lug style valve sandwich mounts between customer supplied standard ANSI/ASME Class 125/ 150 pipe flanges. 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 disc. 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. EPS positioning module is self-calibrating and fully potted to help protect the electronics against vibration and moisture. Valve position can be monitored with the 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. Special wave line seat and disc shape, reduces the required torque and extends the life of the valve. Precision machined 316SS disc with two-piece stem (shaft) construction, enhances the flow capacity of the valve and reduces turbulence. The stem shaft utilizes PTFE/graphite bearings with V-ring seals to preventing leakage.

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.
