Request a Quote View Model Data 800\u201326,000 N Available thrust range 30 \/ 60 \/ 100 mm Maximum stroke options 4\u201320 mA or 1\u20135 V Input signal options \u00b11% Accuracy Reference control accuracy Overview Advantages Technical Data Model Selection Drawings Dimensions Mounting Brackets Applications Selection Guide Linear electric actuation for precise control-valve stem positioning Product Overview Accurate Linear Positioning for Automated Control Valves The 381LS series linear electric actuator converts an electrical command signal into controlled linear stem travel. It can be combined with globe valves and other compatible regulating valves through a selected mounting bracket and stem connection. 01 Closed-loop modulating control: accepts standard process signals and provides position feedback for automation systems. 02 Wide thrust coverage: models range from 800 N to 26,000 N for different valve sizes and shutoff loads. 03 Flexible stroke adjustment: zero point and operating stroke can be adjusted to match the connected valve. 04 Valve package compatibility: multiple bracket codes support a range of common control-valve diameters. Product Advantages Why Choose a Linear Electric Actuator Control Valve The actuator package is configured around required thrust, speed, stroke, valve size, control signal and installation environment. 01 Precision Modulating Control Reference basic error, hysteresis and dead zone are each controlled within the specified catalog limits for repeatable valve positioning. 02 Multiple Thrust and Stroke Options Eight catalog models cover 800 N to 26,000 N with 30 mm, 60 mm or 100 mm maximum travel options. 03 Standard Automation Signals Supports DC 4\u201320 mA or DC 1\u20135 V command signals and DC 4\u201320 mA output feedback. 04 Broad Power-Supply Compatibility AC and DC power options are available for different regions, control panels and industrial electrical standards. 05 Configurable Mounting Brackets Bracket codes A-2 through C-6 support multiple valve diameter ranges and stem-thread arrangements. Main Technical Parameters Electrical, Signal and Control Specifications The following values are translated from the supplied actuator manual and should be confirmed for the final ordered model. 01 Power Supply and Consumption Single-Phase AC AC 110 V 50\/60 Hz; AC 220 V 50\/60 Hz; AC 240 V 60 Hz Three-Phase AC AC 380 V 50 Hz DC Supply DC 24 V, DC 36 V, DC 48 V Type A Consumption 50 VA at rated load Type B Consumption 150 VA at rated load Type C Consumption 220 VA at rated load 02 Signals, Accuracy and Stroke Input Signal DC 4\u201320 mA or DC 1\u20135 V Output Signal DC 4\u201320 mA, load resistance \u2264 500 \u03a9 Basic Error \u00b11% Hysteresis \u2264 1% Dead Zone \u2264 1% Zero Adjustment \u00b125% Stroke Adjustment 20%\u2013100% Power-supply notes: Type C models have higher power consumption and are not offered with nominal DC 24 V, DC 36 V or DC 48 V supply. Supply-voltage deviation should remain within \u00b110%. Specify rated voltage and frequency when ordering. External Wiring Recommended Cable Arrangement Use shielded cable for input and output signals. Do not route the power conductors and signal conductors in the same cable.
