The TVF-M20YNMM TopWorx Switchbox is a rugged valve position monitor designed to deliver precise OPEN and CLOSED feedback for automated quarter-turn valves. Engineered to mount directly to pneumatic or electric actuators, it provides both clear visual indication and dependable electrical signalling for integration with industrial control systems.
Built for demanding environments, this model features a sealed, impact-resistant housing that protects internal components from dust, moisture, and vibration. The high-visibility dome indicator allows operators to confirm valve position at a glance, while the adjustable internal cam system enables accurate switch actuation for consistent performance—even under frequent cycling. Industrial-grade microswitches ensure reliable signalling that supports safety systems, PLCs, and process automation logic.
