IN STOCK - SAME DAY DISPATCH
The Uflow AS80ANB112V1 is a robust, single-acting (spring return) pneumatic rack-and-pinion actuator designed for quarter-turn valve applications.
Engineered to support a max working pressure of 8 bar, an ambient/operating range of -20 °C to +80 °C (for the NBR/nitrile seal variant) and ISO 5211 compatible mounting patterns (F05/F07) for direct mounting to standard valves.
According to the manufacturer’s catalogue, the actuator also supports corrosion-resistant hard-anodised body finish, low air-consumption design, and is approved for hazardous area use (ATEX) when correctly specified.
Key Features
Single-Acting (Spring-Return) Operation – Built-in spring module returns the valve to a safe position upon air failure.
Max Working Pressure ~8 bar – Standard working pressure for the AS80 series.
Operating Temperature Range -20 °C to +80 °C (for NBR/nitrile seals) – Suitable for standard industrial ambient conditions. Nitrile (NBR) Seals – The model code “N” indicates nitrile seal material, offering good general service resistance.
ISO 5211 Mounting Pad (F05 / F07) – Ensures direct universal mounting to many quarter-turn valves without custom adaptors.
Hard-Anodised Aluminium Extruded Body – Enhances corrosion resistance and long service life in field conditions.
Wear-Proof Rack & Pinion Design & Low Air Consumption – Optimised for high cycle duty and efficient supply air use.
ATEX Approved (Hazardous Area Capable) – The catalogue notes “Approved as per ATEX” for the actuator series.

FAQ's
What is the difference between a valve and an actuator?
What types of actuators are available?
The main types of actuators are:
Pneumatic actuators – use compressed air for fast, reliable operation.
Electric actuators – use electrical power for precise control.
Hydraulic actuators – use fluid pressure for high-torque applications.
Each type offers unique advantages depending on the environment, media, and system control needs.
How do I choose the right actuator for my valve?
To select the correct actuator, consider:
Valve type and torque requirement
Power source available (air, electric, or hydraulic)
Operating environment (temperature, humidity, hazardous area)
Control signal type (on/off or modulating)
Matching actuator torque and compatibility with the valve’s ISO mounting ensures reliable performance.
What are the main types of valves used in automation?
The most common valves in automated systems include:
Ball valves – for tight shutoff and quick operation.
Butterfly valves – for larger flow control with compact design.
Globe valves – for precise throttling and flow regulation.
Check valves – to prevent backflow.
Gate valves – for full bore flow isolation.
What’s the difference between a double-acting and spring-return actuator?
Double-acting actuators use air (or power) to both open and close the valve.
Spring-return actuators use air to open (or close) the valve, and a built-in spring to automatically return it to a safe position when power or air is lost — ideal for fail-safe operation.
How often should valves and actuators be serviced?
Regular maintenance intervals depend on operating conditions, but a good rule of thumb is to inspect every 6–12 months.
This includes checking for leaks, lubrication, seal wear, and actuator responsiveness to prevent unexpected downtime.
