Heavy Duty Intelligent Linear Electric Valve Actuator

HUS Linear Stroke Series Electric Actuator Purchase Guide

Step 1: Select Model Size by Thrust, Stroke & Manual Style

Pick the right model based on your required thrust, stroke, and manual override type: HUSS (Spanner), HUSH (Push Handwheel), or HUS (Clutchless Handwheel).:

Step 2: Choose Control Mode & Power Supply Control Mode: On/Off (Code O): Basic full-open and full-close control. Modulating (Codes M1, M2, M3): Precise travel control using 4–20 mA (M1), 0–5 V (M2), or 2–10 V (M3) signals. Smart Control (Code ICM): Built-in LCD screen, non-intrusive infrared remote setup, reverse-run delay, auto phase correction, and optional HART 7.0 fieldbus communication upgrade. Power Supply: 220 VAC (Code D), 110 VAC (Code E), 24 VDC (Code F), 380 VAC (Code I), or 440 VAC 3-Phase (Code J). (Note: 24 VDC is not available on 25 kN & 50 kN models; 380 V / 440 V is not available on basic built-in On/Off models).
Step 3: Confirm Enclosure, Space Heater & OEM Options Explosion-Proof: Standard safe-area type or Exd IIC T6Gb explosion-proof type. Water Protection: IP67 standard (IP68 optional). Space Heater (Code X): Built-in heater to stop condensation and moisture inside the unit in cold or wet places. Custom OEM Options: Standard body color is blue, grey (custom colors available), custom brand nameplates, and custom mounting hole sizes or center distances (for HUS1, HUS2, HUS3, and HUS4).
Step 4: Build Your Part Number (Ordering Code) [Model No.] – [Thrust (T)] – [Control (K)] – [Power (V)] – [Options (B)] Use the coding chart below to build your exact ordering number step-by-step: Model & Thrust (T): Choose your base model and thrust rating based on Step 1. Control Method (K): Select your signal type (On/Off, 4–20 mA, 0–5V, 2–10V, or Smart ICM). Power Supply (V): Check the matrix to confirm your voltage is supported for that model size. Options (B): Add X for an internal space heater, or note any custom mounting/color requests.

Installation & Working Tips:

When installing your actuator on the valve, check these site conditions to keep the unit running smoothly.

Air Temp & Heater: Works in -20°C to +70°C. If below 0°C or in high humidity, add the internal heater (Code X) to prevent moisture.

Pipe Fluid Temp & Pillar Selection:

Under 65°C: Standard pillars; 100°C to 180°C: Medium-heat extended pillars; Above 180°C: High-heat extended pillars (protects motor and electronics)

Mounting Space & Safety: Leave space around the unit for wiring and handwheel turning. For flammable gas areas, choose the certified explosion-proof version.

FAQ About HUS Linear Stroke Series Heavy Duty Intelligent Linear Electric Valve Actuator

Q1: What is the maximum thrust of the HUS heavy duty intelligent linear electric valve actuator?

The maximum output thrust is 50 kN. The HUS series covers thrust outputs from 1.5 kN up to 50 kN across different frame sizes to fit various control valve, globe valve, and gate valve requirements.

Q2: How do you match the right HUS heavy duty linear electric actuator to our valve thrust?

Send us your required operating thrust (in kN) and stroke length. We calculate and match the right HUS model with a 20% to 30% safety margin to ensure reliable valve shut-off under full differential pressure.

Q3: Our valves do not have standard mounting flanges. How do you make sure the HUS linear electric valve actuator fits?

Just send us your valve bonnet dimensions (pillar spacing, bracket height, and stem thread size). We machine the mounting pillars and stem adapter directly to match your valve, so the actuator bolts straight on without extra rework.

Q4: Which models in the HUS linear electric actuator series include the LCD display screen?

Only smart models with the ICM board come standard with an LCD screen and infrared remote control. The smart ICM series can run as either Smart On/Off or Smart Modulating. Standard On/Off and standard modulating models (without ICM) do not have a display screen.

Q5: Can we calibrate stroke and travel limits on the HUS smart linear actuator without opening the housing cover on site?

Only on HUS smart ICM models (such as HUS-05-ICM or HUS-10-ICM). With the ICM board, you can set travel stroke limits, action direction, and sensitivity from the outside using the infrared remote through the LCD window. For standard models without the ICM board, you must open the top cover to adjust the internal limit switch cams manually.

Q6: Is HART communication included on the HUS intelligent linear electric valve actuator, or is it an extra option?

It is an option. The standard HUS smart ICM model includes 4–20 mA analog control, an LCD screen, and infrared remote setup. The HART 7.0 communication module is an optional factory upgrade for use with standard field communicators.

Q7: What happens if the 4–20 mA control signal is lost on a HUS smart electric actuator?

On modulating and smart ICM models, you can preset the fail-safe action in advance: stay in place, drive fully closed, or drive fully open if the 4–20 mA signal drops out. If main electrical power is lost, the internal self-locking drive screw keeps the valve locked in place.

Q8: Does the manual handwheel spin when the HUS motorized linear actuator is running?

No. Across all manual handwheel options on the HUS series (Spanner, Push Hand Wheel Operation, or Clutch Less Hand Wheel), the internal drive design keeps the handwheel stationary while the motor runs. You can operate the handwheel directly when needed without pulling any clutch lever.

Q9: How do we protect the HUS intelligent electric actuator from hot steam lines (above 180°C)?

For pipe temperatures above 180°C, we provide extended stainless steel mounting pillars. This extra spacing prevents pipe heat from conducting into the aluminum housing, motor, and internal electronics.

Q10: Can the HUS heavy duty intelligent linear electric actuator be made explosion-proof?

Yes. We can provide the HUS series as a certified Exd IIC T6 Gb explosion-proof actuator for hazardous areas. Explosion-proof protection is an optional factory upgrade with an extra cost.

Q11: What test reports and certificates do you provide with each HUS smart actuator shipment?

Every shipment comes with a standard factory test report covering thrust, stroke, operating speed, and electrical insulation tests. We also provide CE, ISO 9001, SIL3, and certified Exd explosion-proof documentation upon request.

Q12: What is your standard factory lead time for wholesale batch orders of HUS linear actuators?

Our standard factory production lead time for wholesale orders is 15 to 25 days. We keep pre-machined housings, motors, and control boards in stock to fulfill batch orders quickly.

Q13: Can you put our brand logo and custom model numbers on the HUS heavy duty linear electric valve actuator nameplates?

Yes. We offer OEM private-label options using either laser-engraved stainless steel nameplates or heavy-duty weather-resistant stickers printed with your brand logo and part numbers. Custom housing colors are also available for bulk orders.
