In many hydraulic and pneumatic systems, it is often required not only to completely open / shut off the flow of a particular medium, but also to smoothly regulate it. In fan coil units and air conditioners, this primarily concerns the supply of refrigerant (any - water, antifreeze, special mixtures). Two-way valves serve this purpose. They contain, in accordance with the name, two branch pipes - inlet and outlet (do not confuse during installation: as a rule, the direction of flow is strictly defined), as well as the actual control element (special spool, conical needle, flat, cylindrical or ball valve, and others) with a drive for moving. The drive, like other valves, can be mechanical, hydraulic, pneumatic and electric. Due to the huge range of two-way valves (various brands, operating principles, installation dimensions, electrical parameters, types of liquids to be processed, their pressure, flow, temperature, etc.), it is physically impossible to maintain the presence of all models even in the catalog.
