ABSTRACT:
A control valve for a solar heating system is disclosed. The valve has a valve body which defines four chambers disposed end to end. A valve operating rod is movable axially through all four chambers uder motor control and carries a valve member for directing liquid through the valve. In one position of the valve member, incoming liquid is directed to an outlet for connection to a solar collector and liquid returning from the collector can flow through the valve body and back to the swimming pool. In the other position of the valve member, the liquid bypasses the collector and is directed back to the pool while liquid in the collector drains back into the valve body through the outlet and is removed by suction from a drain-down chamber in the valve body.
