ACT991M Modulating Actuators w / Gap Detection

An electro-mechanical actuator with Gap Detection technology. The actuator monitors the force exerted from the valve stem and stops when a predetermined value is reached. This ensures the actuator stroke accurately matches the valve stroke (to within 0.1mm).

Features and benefits:

• Modulating actuators enable flow rate changes, and consequently heat output changes, to quickly match demand requirements.
• Allow all intermediate flow rates between full flow and no flow.
• The actuator can actively communicate its stroke position to the control system to monitor building operations.
