At CRH 2017, Castel will showcase its 3-way motorized ball valves which are designed for installation on commercial refrigerating systems as well as for use in civil and industrial conditioning plants.
Models in the 3-way valves series including 6690M, 6690EM, 6697EM, and 6698EM, operate as a changeover valve, with the inlet in central position and the two outlets in side positions. These valves must be coupled directly to the electrical actuators which are supplied in the same package as the valve, without a flanged adapter between the two parts. After coupling, it is possible to remote control the valve’s movement or use manual controls for all but the actuator.
Series 6690M features allowable pressure up to 45 bar, equipped with copper connections, and is suitable for systems with traditional fluids including R134a, R22, R404A, R407C, R410A, and R507.
