Each Castel ball valve uses a pivoting ball to control the flow of freon. When the hole of a ball valve is in line with the direction of flow of ...the freon, the passage of that refrigerant is allowed. Alternatively, when the ball of a ball valve is turned 90 degrees, the flow is stopped completely. Within the Castel ball valve category, the refrigerant flow direction can be adjusted in both directions. Ball valves are robust and very reliable valves, retaining the ability to operate consistently after many cycles. They close and open safely even after long periods of non-use. Flow can also be controlled by opening or partially closing the ball valve. Castel ball valves come with equal ODS weld connections, with diameters ranging from 6 to 64 mm. Mai mult
