KMC Controls MCP-8031-3102 Actuator

The KMC Controls MCP-8031-3102 Actuator is a heavy-duty pneumatic damper actuator specifically engineered for high-temperature environments and smoke control systems. Constructed with a durable metal body, this unit is designed to meet UL555S standards for leakage-rated dampers, maintaining operation at 450??F for critical exhaust and containment sequences. Featuring a 5-10 PSI spring range and a precise 1-11/16 inch stroke, this linear pneumatic actuator provides reliable proportional control or two-position operation for VAV terminals and air handling units.

Equipped with a self-lubricating Delrin plastic bushing and a right-angle mounting bracket, the MCP-8031-3102 ensures long-term performance in ceiling plenums and tight mechanical spaces. The 8 sq. in. effective diaphragm area translates to a damper rating of up to 10 sq. ft. for two-position applications. This HVAC pneumatic component integrates seamlessly into legacy and modern pneumatic control systems, offering the mechanical advantage needed for precise smoke damper positioning without the heat-related failure risks of non-metallic alternatives.

• UL555S Compliance: Rigorously tested for smoke control systems, capable of positioning dampers during elevated temperatures up to 450??F.
• Plenum Rated: The rugged metal construction allows for code-compliant installation in ceiling plenums and restricted access areas.
• Maintenance-Free Bushing: Utilizes a high-performance Delrin (plastic) bushing for smooth shaft travel and reduced friction without lubrication.
• Universal Mounting: Furnished with a standard right-angle bracket to simplify retrofit or new installation on VAV air terminal units.

• What is the torque rating for this pneumatic actuator? Based on the 5-10 PSI spring range and 20 PSI supply, this unit delivers approximately 34 in-lb retracted torque and 67 in-lb extended torque.
• Does this include the clevis and cotter pin? No, the MCP-8031-3102 is the actuator and bracket assembly only; drive linkage and clevis accessories must be ordered separately.
• Can this be used for gradual or two-position control? Yes, this actuator is suitable for both gradual (proportional) and two-position applications depending on the control signal applied.
