Pneumatic Actuator

The Pneumatic Actuator is a high-performance device designed to provide reliable and efficient control for industrial automation processes. With robust construction and versatile operation modes, it ensures precise movement in various pneumatic systems.

Uflow Pneumatic Actuators – Single Acting & Double Acting (AD Series & AS Series)

Compact | Patented Design | High Efficiency

Uflow’s Pneumatic Rotary Actuators are engineered for precision control in valve automation systems, offering two efficient configurations—Single Acting (AS Series) and Double Acting (AD Series). With a patented aluminium-free rack & pinion mechanism, these actuators deliver reliable, smooth, and torque-optimized performance for various industrial applications.

1) Uflow Single Acting Pneumatic Actuator – AS Series

Fail-Safe Operation
The Single Acting actuator uses compressed air to operate in one direction and a spring return mechanism to revert the actuator to its original position when air pressure is removed—ideal for fail-safe or emergency shutdown applications.

Key Features:

Spring Return Mechanism – Ensures automatic closure in power loss or emergency situations
Low Air Consumption – Compact design minimizes air volume requirements
Hard Anodized Body – Superior corrosion and wear resistance
Smooth Stroke Movement – Reduces stress on valve seals and seats
Maintenance-Free Design – Long service life with minimal servicing
Design Standard: ISO 5211
Certified: ATEX-compliant for use in hazardous areas

Technical Highlights:

Max Working Pressure: 8 bar
Temperature Range:
- NBR: –20 °C to +80 °C
- Viton: –20 °C to +125 °C
- Fluorosilicone: –60 °C to +110 °C
Stroke Adjustment:
+5° Overtravel for opening

–5° Undertravel (adjustable)

Air Volume Efficiency: Uses significantly less air than competing brands

2) Uflow Double Acting Pneumatic Actuator – AD Series

Bidirectional Control
The Double Acting actuator uses air pressure to move in both directions, providing high torque output and control precision for critical valve operations.

Key Features:

High Torque in Both Directions – Precise actuation for open/close operations
Compact & Lightweight – Ideal for limited space applications
Low Air Volume Usage – Energy-efficient operation
Anodized Aluminium Housing – Long-lasting protection against wear and corrosion
Smooth, Jerk-Free Motion – Enhanced valve life and operational accuracy
Design Standard: ISO 5211
Certified: ATEX-approved

Technical Highlights:

Max Working Pressure: 8 bar
Temperature Range:
- NBR: –20 °C to +80 °C
- Viton: –20 °C to +125 °C
- Fluorosilicone: –60 °C to +110 °C
Stroke Adjustment:
+5° Overtravel

–5° Undertravel (adjustable)

Applications for Both Models

Valve automation in oil & gas, chemical plants, power stations, water treatment, pharmaceuticals, and food processing
Ideal for ball valves, butterfly valves, and plug valves
Suitable for automated control systems, remote actuation, and safety shutdowns
