AAFrequently Asked Questions
What are JB's valves made of?
JB ball valves feature a brass body construction that resists corrosion and offers durability as well as long-lasting performance.
What is the function of spring-loaded check valves?
When refrigerant flows through the valve in the correct direction, the pressure pushes the ball up against the spring, which allows the refrigerant to flow through the valve uninterrupted. However, if there is a pressure differential in the opposite direction, the spring pushes the check valve down onto the valve seat, preventing the refrigerant from flowing back through the valve.
What is a capillary tube?
Capillary tubes are located between the condenser and the evaporator in a refrigeration system. It controls the flow of refrigerant from the high-pressure side of the system to the low-pressure side, thus providing a pressure drop to help the refrigerant to evaporate and cool.
