截止閥

截止閥

Shut-off ball valves are used to open or shut off refrigerant flow in refrigeration systems and are suitable for bi-directional flow. They are used in liquid, suction, and hot gas lines, which makes them relevant wherever reliable isolation is needed during installation, service, or system operation. In cold room applications, shut-off ball valves are part of the wider line-component layer of the refrigeration circuit and support safe, practical system handling. Beyond cold rooms, the same valve category is also used in refrigeration, freezing, air conditioning, chillers, heat pumps, and transport refrigeration applications.
