ILEA Electric Linear Actuator
Warren Controls 1800E: Control Valve with ILEA Actuator
The Warren Controls 1800E pairs a high-capacity globe valve body with an ILEA linear electric actuator. It provides precise flow, pressure, or temperature control through two-way (1840/1843) and three-way (1850/1852) configurations. Technical documentation for ILEA assemblies primarily covers sizes from 2½ to 12 in. Valve selection depends on the process media, Cv requirements, operating pressures, control signal, and fail-safe functionality.
Control and Feedback
Analog current or voltage signals for modulating control, featuring position feedback depending on the actuator. Signal type and range must be specified.
Instrument-air-free actuation
ILEA linear electric actuators provide a reliable alternative when your facility favours an electrical power supply over a pneumatic system. Thrust and stroke ratings can be verified directly within the configuration.
Shut-off Performance
Depending on the model: fail-in-place or capacitive fail-safe actuation. The final position must never be assumed without selecting the corresponding design.
Valves and Compatible Media
Body available in cast iron, WCB cast steel, or CF8M stainless steel; packing and seals in TFE, EPDM, or graphite. Temperature limits depend on the selected materials and valve configuration.
1800E: Two-Way, Mixing, and Diverting
The ILEA actuator is compatible with both two-way and three-way valve bodies. Performance capabilities are determined by the number of ports, plug balancing, and the hydraulic function.
TWO-WAY · CONTROL
1840 / 1843 · 2-Way
The 1840 utilizes an unbalanced plug, whereas the 1843 features a balanced plug designed to reduce operating thrust under high differential pressures. Both models are engineered for precise modulating control of liquids, gases, or steam, with the 1843 specifically suited for relatively clean media.

3-WAY · MIXING
1850 · Mixing Valve
The 1850 combines two inlets into a common outlet for fluid mixing, particularly in thermal loops. ILEA packages within this series are documented starting from 2½ in.

3-WAY · DIVERTING
1852 · Diverter Valve
The 1852 diverts a common inlet to two outlets. It delivers Class II shut-off sealing and features a 50 psid limit between the upper and lower ports. Reverse-flow operation for mixing applications requires manufacturer validation.

Materials, Temperature, and Electrical Compatibility
A standard range limit does not apply to all configurations. The body, trim, seals and packing, actuator, and operating environment must be evaluated as an integrated system.
VALVE DESIGN & CONSTRUCTION
Body and End Connections
Cast iron with Class 125/250 flanges depending on size; WCB carbon steel or CF8M stainless steel with Class 150/300 flanges. Pressure class and face-to-face dimensions must be confirmed against the submitted approval drawing.
Trim and Sealing Solutions
316 stainless steel or Alloy 6 depending on the two-way configuration; three-way models feature a 316 stainless steel linear trim. Note that O-rings in select balanced designs are not compatible with all solvents.
Operating Temperatures
800°F applies only to select customized 1840 or 1850 configurations. Model 1843 features lower thresholds, and 6 to 12 in. 1852 models are rated up to 150°F per manufacturer specifications. Be sure to also verify the actuator's ambient temperature limits.
ILEA ELECTRIC ACTUATOR
Power and Signal
Depending on the model: 24 VAC/VDC, 115 VAC, or other available voltages. Modulating control via 0/4–20 mA or 0/2–10 V; please confirm your specific protocol requirements.
Fail-Safe Mode
Fail-in-place or capacitive fail-safe functionality depending on the selected actuator. Fail-open or fail-closed positioning must be specified at the time of order; it is not field-reversible.
Protection and Accessories
Documented IP67 rating on ILEAs; local control, limit switches, anti-condensation heaters, and USB configuration available depending on models and options.
Please specify the media, flow rates and pressures, available voltage, control signal, and the required fail-safe mode.
Where should you deploy the Warren Controls 1800E electrically actuated valve?
Electric actuation is the optimal choice when PLC-controlled modulation is required or when an instrument air supply is unavailable. Process media characteristics and valve design limitations remain the governing factors.
ELECTRIC LINEAR ACTUATORS
ILEA Linear Electric Actuators
The ILEA range features multiple sizes of linear electric actuators. Specifically, the manufacturer documents the A, B, and G series, each delivering distinct thrust ratings and stroke lengths. Proper selection depends on your valve configuration, differential pressure requirements, and specified operational functions.
ILEA A / B / G
Documented nominal thrust values: approximately 1,011 lbf (A), 1,798 lbf (B), and 4,496 lbf (G). Valve-actuator pairing is confirmed based on the exact model.
4–20 mA or 2–10 V
Analog signal and position feedback depending on the part number. Modulating or on/off control; integrated positioning functions available on select models.
Fail-safe, local control, and IP67-rated
Depending on the configuration: fail-in-place or capacitive fail-safe, local controls, limit switches, USB diagnostics, and an IP67-rated enclosure.
