Engine Overspeed Protection System
TMZ-124-77 Valve + RLZ-100 Control Lever + CHW-300 Cable

Protect your diesel engines with a proven, fully integrated air intake shutdown solution designed for fast, reliable response in critical situations. The combination of the TMZ-124-77 shutdown valve, RLZ-100 manual control lever, and CHW-300 cable delivers a complete overspeed protection system engineered to safeguard personnel, equipment, and operations.

At the heart of the system, the TMZ-124-77 valve automatically closes the engine air intake when dangerous overspeed conditions occur—effectively stopping runaway engines before damage can escalate. Paired with the RLZ-100 manual override lever, operators gain immediate, hands-on control for emergency shutdown or start override when needed. The CHW-300 heavy-duty cable ensures smooth, dependable mechanical actuation between components, even in harsh environments.

Built for demanding industrial applications, this system is ideal for oil & gas, mining, power generation, and mobile equipment where safety and reliability are non-negotiable.
