Product Description:
IMI Norgren non-return valves are high-quality inline one-way pneumatic components designed to allow free-flow compressed air in a single direction while completely preventing any reverse backflow within pneumatic circuits. This product line includes four primary families: the heavy-duty brass S/520-S/532 threaded non-return valves, the push-in tube-to-tube T50P non-return valves, the lightweight and compact T55 inline non-return valves, and the T60 Air Fuse inline excess-flow automatic shut-off safety valves.
The S/520-S/532 heavy-duty series features a robust brass body engineered for high-pressure industrial applications, capable of handling pressures up to 16 bar. These valves are available with G or NPT thread options and also offer a high-temperature variant with FPM seals that can operate at temperatures up to +150°C.
The T50P push-in non-return valves utilize a quick-connect system designed for outer diameter tubes ranging from 4 to 12 mm. They support vacuum conditions as low as -0.9 bar and feature an ultra-low cracking pressure between 0.03 and 0.05 bar. Their design allows for rapid and straightforward field assembly without the need for thread sealing.
The T55 inline non-return valve is a silicone-free, lightweight model with an aluminum body. It boasts a low cracking pressure of 0.05 bar and a compact size, making it ideal for installations with limited space. It can operate at working pressures up to 10 bar and is available in port sizes ranging from G1/8 to G1/2.
The T60 Air Fuse is a specialized uni-directional excess-flow shut-off safety valve. It automatically cuts off the air flow in the event of a hose rupture or significant leakage and resets itself once the fault condition is cleared. This valve is designed to protect flexible hoses and complies with industrial pneumatic safety regulations.
All Norgren non-return valves are designed for use with filtered compressed air, whether lubricated or non-lubricated. They undergo rigorous testing in accordance with the ISO-6358 standard and are widely used in factory automation pneumatic circuits.
Features:
Our product line includes multiple series options to suit various industrial needs. These range from the heavy-duty threaded models S/520-S532 to the push-in T50P series, the compact T55, and the safety air-fuse T60.
Designed to operate within a wide pressure range, these devices function efficiently from a vacuum of -0.9 bar up to a maximum of 16 bar, accommodating diverse application requirements.
With a low cracking pressure starting at just 0.03 bar, the valves ensure minimal flow resistance when opening, promoting energy efficiency and precise control in your systems.
Connectivity is versatile, featuring G or NPT threads as well as push-in tubes with outer diameters ranging from 4 to 12 mm, allowing seamless integration into existing setups.
Material options are tailored for durability and performance, including brass and aluminium bodies paired with NBR seals. For high-temperature applications, optional FPM seals are available.
The temperature range spans from -20°C to +80°C under standard conditions, with the S-series offering an extended high-temperature capability of up to +150°C for more demanding environments.
The T60 Air-Fuse model provides enhanced safety features such as hose-burst protection, automatic reset functionality, and a tamper-proof design to ensure reliable operation and user security.
Installation is straightforward with a simple inline, line-mount configuration. The compact structure enhances space efficiency while delivering high reliability and a long service life.
These devices are compatible with filtered compressed air and inert gases (specifically T60), and can handle both lubricated and non-lubricated air media, ensuring broad applicability across different systems.

Applications:
The realm of factory industrial automation extensively utilizes pneumatic control circuits to optimize operational efficiency. These systems are integral in managing a variety of equipment such as pneumatic machine tools, packaging machinery, and textile equipment, ensuring precise and reliable performance.
In robotic applications, pneumatic actuator loops are commonly employed to facilitate smooth and accurate movements. Additionally, mechanisms like cylinder back-flow prevention play a crucial role in maintaining system integrity and preventing malfunctions.
Protecting key components such as compressors, air dryers, and air preparation units is vital in pneumatic setups. Implementing safety measures helps extend the lifespan of these devices and guarantees consistent operation across different industrial environments.
Safety is further enhanced through flexible air-hose rupture protection. For example, the mandatory application of the T60 Air Fuse provides a reliable safeguard against sudden hose failures, minimizing downtime and potential hazards.
Pneumatic systems are also widely used in conveying equipment and material-handling operations. Their versatility makes them suitable for diverse industries, including automotive assembly lines and printing machinery, where efficient movement and control are paramount.
Moreover, vacuum pneumatic circuits, such as those found in the T50P series, offer specialized solutions for applications requiring vacuum generation and control, expanding the scope of pneumatic technology in industrial automation.
