Motorized Zone Valve
SKD series 2-position hydraulic valves are used in domestic and small commercial applications to control the flow of hot and/or cold water or glycol solution up to 50% concentration. These 3-Way valves are designed for ON-OFF control and can be piped for diverting or mixing valve applications for domestic hot water service, in central heating and/or cooling systems; or for individual room temperature control (fan coil, radiator or convector applications).
