Abstract
A valve assembly includes a valve installed in a fluid/liquid supply line, and a water circulation pipe that has a first end in fluid communication with a water supply line and a second end in fluid communication with an inner volume of the valve. Some water flowing in the water supply line is diverted through the water circulation pipe and circulates in the valve. The water that is diverted through the water circulation pipe and circulates in the valve has a sufficient flow to prevent freezing and/or water stagnation in the valve.
