This is a comparative control application. The two-way valve type controls the flow to the heat exchanger based on the signal from the controller, maintaining a constant temperature on the load side. The three-way valve type allows a portion of the fluid to bypass the heat exchanger based on the controller's signal, mixing the fluid that passes through the heat exchanger with a three-way valve to maintain a constant temperature on the load side. Without using a three-way valve, two control motors (electric actuators) operate dampers, butterfly valves, and ball valves for the heat exchanger inlet and bypass, controlling in a similar manner. 【Features】 ■ Two-way valve Maintains a constant temperature on the load side by controlling the flow to the heat exchanger with a two-way valve. ■ Three-way valve Maintains a constant temperature on the load side by mixing the fluid that passes through the heat exchanger with a three-way valve. Without using a three-way valve, two control motors (electric actuators) operate dampers, butterfly valves, and ball valves for the heat exchanger inlet and bypass, controlling in a similar manner. *For more details, please contact us.
