Description
Product Overview
Spirax Sarco EL4600 series is an electric actuator designed for proportional control applications. It operates DN15 to DN50 two-way and three-way valves to regulate fluid flow in industrial systems. The unit accepts multiple input signals and provides corresponding output feedback signals.
Key Features
- Delivers 2000N maximum thrust with a 20mm linear stroke.
- Built-in torque switch protects the valve and actuator during overload conditions.
- Auto-calibration system automatically recognizes 0-100% stroke limits.
- Selectable operating speeds of 100 step or 200 step based on application requirements.
- Synchronous motor maintains stable speed during voltage fluctuations.
- Includes a manual handwheel for operation during power failures.
- IP54 enclosure rating (DIN40050) with Class E motor insulation (IEC).
- EMC safety certified, complying with EN60730-2-14 (1997) and EN60730-1:2000 standards.
