KMC Controls HVAC Control Valves & Actuators

KMC Controls HVAC Control Valves & Actuators

KMC Controls has been engineering precision HVAC control hardware since 1969, and their HVAC control valves and actuators represent some of the most field-proven components available for commercial building automation. Founded as the Kreuter Manufacturing Company in New Paris, Indiana, KMC has spent decades refining the mechanical and electronic heart of building control systems — the actuators and valves that physically move air and fluid in response to commands from thermostats, controllers, and building automation networks.

Actuators Built for Precision and Durability

KMC Controls produces both electronic and pneumatic actuators designed to automate the movement of valves, dampers, and other mechanical devices within HVAC systems. Their direct-coupled actuator lineup delivers strong torque outputs — with models rated at 180 or 320 in-lb over a 94° angular rotation — to handle large control air dampers and valves reliably. Proportional actuator models accept 0–10 VDC, 2–10 VDC, or 4–20 mA control signals, making them compatible with virtually any thermostat, controller, or building automation system. A standout engineering feature is the "anti-jitter" circuitry, which reduces hunting and unnecessary wear on valve packing and damper components caused by undamped analog input signals. Capacitor-driven fail-safe models add an extra layer of operational reliability, with switch-selectable fail direction for critical applications.

Control Valves for Heating, Cooling, and Fluid Applications

KMC's control valve lineup covers a broad range of hydronic and fluid applications, including two-way and three-way ball valves available in sizes from 1/2 in. to 2-1/2 in. and Cv ratings spanning a wide range to suit everything from small zone circuits to large-tonnage systems. These valves are engineered for hot water, chilled water, and steam service — the core media found in commercial HVAC hydronic systems — and are built to withstand the constant cycling demands of occupied commercial buildings. The actuators and valves are designed to integrate seamlessly with KMC's own control ecosystem, ensuring out-of-the-box compatibility and reducing commissioning time for installing contractors.

U.S.-Made Quality and Open-Protocol Integration

All KMC Controls products are manufactured in New Paris, Indiana under an ISO 9001:2015 certified quality management system, meaning each valve assembly and actuator is tested and validated before it ships. KMC also holds patents covering pneumatic, electronic, and digital actuators and valves — a testament to the engineering depth behind their product lines. Because KMC designs around the BACnet® open protocol, their actuators and valves integrate cleanly into modern DDC (Direct Digital Control) architectures and IoT-connected building management platforms. Whether you are retrofitting an older pneumatic system or specifying components for a new BACnet-networked facility, KMC Controls offers a consistent, trusted hardware foundation.
