Product Overview

Choose an XR22 wiring option above:

  • 9 to 24V AC/DC (auto detects voltage)
  • 110 to 230V AC

This motorized ball valve will allow full flow without restriction, something that solenoid valves lack. When the actuator is powered the valve will fully open and at the same time it will charge the internal capacitor. The internal capacitor powers the motor to turn the ball 90 degrees back to its normal position when power is removed. This actuator requires a minimum energized cycle of at least 60 seconds to ensure the internal capacitor is fully charged and has enough power to close the valve completely. Cycle times shorter than 60 seconds may result in partial or incomplete closures. After the valve is fully open, a negligible amount of power is needed to maintain the capacitor charge. Once power is cut/lost, the power from the charged capacitor will proceed to close the valve. Unlike standard solenoid valves, these electric ball valves are bi-directional, meaning media may flow in either direction through the valve. 


The actuator takes approximately 4-5 seconds to fully close/open the 1/4 turn ball. This slow response time will eliminate water hammer, something that is common among solenoid valves. The ball valve has a 304 stainless steel body, a stainless steel ball (driven by metal gears), a PTFE ball seat and an EPDM seal. This combination makes it compatible with many different chemicals as well as potable water applications. While the actuator is weather resistant, we advise to use caution when installing outdoors. This housing is rated IP67 and NEMA 4 and may be directly connected using its 20" lead wires. The valve is recommended to be installed with the actuator up, especially in applications with a high degree of vibrations.

We also offer a 3-Wire version without the auto return function.
