Fine Smart Series Electric Quarter Turn Valve Actuator

Fine Smart Series Electric Quarter Turn Valve Actuator

OVERVIEW

The FRY Fine Smart Series Electric Valve Actuator represents a revolutionary breakthrough in compact, intelligent valve automation. Engineered with state-of-the-art micro-mechanics and high-integration digital electronics, its overall physical volume is reduced to merely ~35% of conventional quarter-turn actuators with comparable torque capacity. This compact form factor significantly minimizes pipeline footprint, structural overhang stress, and field installation overhead.

Designed for high-precision 90° rotary valve automation, the Fine Smart series integrates the worm gear and drive shaft directly into a single unified output mechanism, allowing the valve stem to insert directly into the actuator core. This shortens the mechanical force arm and ensures superior drive stiffness and torque transmission accuracy. With intelligent CNC digital calibration, multi-voltage power compatibility (DC24V to AC380V), IP67/IP68 ingress protection, and Exd IIB T4 Gb explosion-proof certification, the Fine Smart series delivers outstanding reliability across automated industrial fluid networks.

FEATURES OF ELECTRIC ACTUATORS

1. Ultra-compact volume: The overall physical volume is only about 35% of similar products with the same torque output;

2. Lightweight and exquisite design: Smooth cast aluminum housing effectively shields internal electronics and reduces electromagnetic interference;

3. Precision wear-resistant gearing: Precision worm gear and worm shaft are perfectly harmonized; integrated output eliminates connection backlash;

4. Convenient and maintenance-free: Exempt from routine inspection points, no oil replenishment required, rustproof and waterproof, arbitrary installation angle;

5. Comprehensive multi-protection: Equipped with electrical limit, mechanical travel limit, motor thermal overheat protection, and dehumidification space heater;

6. Multi-speed travel options: Wide range of operating speeds available (5s, 8s, 10s, 15s, 20s, 26s, 30s, 60s, 100s) to meet rapid shut-off or anti-water-hammer needs;

7. CNC intelligent digital adjustment: Highly integrated intelligent module enables digital setting, digital calibration, and self-diagnosis without an external positioner;

8. High electrical insulation and safety: Passed AC1500V/AC1800V dielectric withstand voltage tests; Class H high-temperature motor ensures operational safety;

9. High full-load starting torque: Provides high starting torque under full load whether the valve is fully open, fully closed, or at intermediate throttling positions;

10. Heat-treated alloy steel gear train: Made of high-strength alloy steel with advanced heat treatment, capable of withstanding severe cyclic fatigue and impact loads;

11. Detachable handle with storage clamp: Detachable manual crank handle with dedicated clamp on the limit bolt ensures the hex wrench/handle is never lost on site;

12. Integrated worm gear and drive shaft: Monolithic transmission construction provides long-term operational stability and high torque transmission fidelity;

13. Captive cover bolt design: Stainless steel cover bolts are captured to prevent them from dropping out during field wiring and maintenance;

14. Stainless steel travel limit bolts: Stainless steel travel stop screws and internal cams provide precise 0°~90° (±5°) stroke adjustment;

15. Anti-aging sintered glass indicator: High-strength sintered glass lens inspection window provides durable, anti-deformation, UV-resistant visual valve position monitoring;

16. Encapsulated control servo unit: The control servo module features high thermal insulation, moisture resistance, and dust-tight protection for harsh process environments.

PRODUCT ADVANTAGES

Diversified needs

Modern automated plant layouts and skid-mounted process modules increasingly require space-saving, lightweight, and versatile actuation solutions. The FRY Fine Smart series addresses these requirements by offering wide torque options (20 N·m to 2000 N·m), comprehensive voltage selections (DC24V, AC24V, AC110V, AC220V, AC380V), and versatile control circuit options (on-off, passive dry contact feedback, opening signal, and 4-20mA/0-10V analog modulating).

Superior performance

Quality Assurance

Every Fine Smart actuator is subjected to rigorous multi-stage quality control, including 100% full-load torque testing, AC1500V dielectric insulation screening, high-pressure waterproof testing, and comprehensive calibration of digital position feedback signals.

Long warranty period

MAIN FUNCTIONS

Explosion Proof

The second-generation Fine Smart series features certified flameproof explosion-proof construction (Ex d ⅡB T4 Gb). The cylindrical stopper precisely matches the explosion-proof joint surface, satisfying safety requirements in over 90% of explosive gas environments (Group IIA, IIB, T1-T4) such as chemical, oil, and gas processing plants.

Colors

Available in standard industrial gray and customizable surface color coatings (RAL / Pantone). The electrostatically applied polyester dry powder coating provides outstanding resistance to chemical washdown, UV degradation, and outdoor atmospheric corrosion while maintaining an elegant aesthetic.

Protection grade

Certified to IP67 ingress protection standards, effectively solving the common issues of low ingress protection and poor environmental sealing found in traditional explosion-proof actuators. Optional submersible IP68 construction is available for flooded pit or outdoor washdown service.

Low-temperature

Standard ambient operating range is -30°C to +60°C. For severe cryogenic or sub-zero northern climate installations, optional low-temperature modifications extend the operational capability down to -40°C with specialized low-temperature seals, synthetic lubricants, and internal anti-condensation space heaters.

CONTROL MODE

External control

Standard on-off actuators output passive dry contact limit signals (full open / full close) and intermediate opening feedback signals to external PLC/DCS systems for remote valve status interlock and supervisory control.

Integrated control

The high-court integrated intelligent control module embeds microprocessor-based servo positioning directly on board. It supports digital parameter configuration, precise zero/span auto-calibration, and multi-function self-diagnostics without requiring an external positioner.

Fieldbus

Supports digital communication fieldbus integration (Modbus RTU, Profibus-DP), enabling multi-drop digital networking, remote travel calibration, diagnostic telemetry transmission, and simplified pipeline cabling infrastructure.
