KMC Controls MCP-1040-5208 Actuator Els PW 17895 What is the primary functionThe KMC Controls MCP 1040 5208 Actuator is a heavy duty pneumatic damper actuator engineered for precise modulation in commercial HVAC systems. This 4 inch stroke actuator is designed to produce 8 13 PSI of spring range, providing the necessary torque for both gradual and two position applications. To ensure rock solid mechanical linkage, this model features a B joint (ball joint) connection, which minimizes hysteresis and prevents binding during high
