Product Description:
IMI Norgren non-return valves are premium inline one-way pneumatic components designed to allow free flow of compressed air in one direction, while completely preventing any reverse back-flow within pneumatic circuits. This product range includes four main families, each tailored to specific applications and operating conditions.
The first family, the heavy-duty brass S/520-S/532 series, features robust brass bodies suitable for high-pressure industrial environments up to 16 bar. These valves come with G and NPT thread options and offer a high-temperature variant with FPM seals that can withstand temperatures up to +150°C.
Next, the T50P push-in non-return valves utilize a quick-connect tube design compatible with outer diameter tubes ranging from 4 to 12 mm. They support vacuum conditions as low as -0.9 bar and have an ultra-low cracking pressure between 0.03 and 0.05 bar. Their design enables fast and straightforward installation without the need for thread sealing.
The T55 inline non-return valve is a lightweight, compact check valve built with a silicone-free aluminum body. It features a low cracking pressure of 0.05 bar and is ideal for installations with limited space. This valve can operate at pressures up to 10 bar and is available in port sizes ranging from G1/8 to G1/2.
Lastly, the T60 Air Fuse is a unique uni-directional excess-flow automatic shut-off safety valve. It automatically stops air flow in the event of a hose rupture or significant leakage and resets itself once the fault is corrected. This valve is designed for flexible hose safety protection and complies with industrial pneumatic safety regulations.
All Norgren non-return valves are intended for use with filtered compressed air, whether lubricated or non-lubricated. Each valve undergoes rigorous testing according to the ISO-6358 standard and is widely used in factory automation pneumatic circuits.
Features:
Our product lineup includes multiple series options to meet various needs. These include the heavy-duty threaded S/520-S532, the push-in T50P, the compact T55, and the safety air-fuse T60.
Designed to operate efficiently under a wide range of pressures, the system supports vacuum pressures as low as -0.9 bar and can handle a maximum pressure of up to 16 bar.
With a low cracking pressure starting at just 0.03 bar, the valves ensure minimal resistance during opening, allowing for smooth and efficient flow control.
A variety of connection types are available, including G and NPT threaded options as well as push-in tube connections compatible with outer diameters ranging from 4 to 12 mm.
The materials used in construction offer flexibility as well, with bodies made from either brass or aluminium. Sealing options include standard NBR seals and optional FPM seals designed for high temperature applications.
The temperature range for standard models spans from -20℃ to +80℃, while the S-series variants offer an extended high-temperature capability up to +150℃.
Featuring the T60 Air-Fuse, the system provides hose-burst protection with an automatic reset function, incorporating a tamper-proof safety design for enhanced security.
Installation is straightforward thanks to its simple inline, line-mount design. The compact structure ensures high reliability and a long service life, making it ideal for various industrial applications.
The media compatibility includes filtered compressed air, inert gases (specifically for T60 models), and both lubricated and non-lubricated air, offering versatile operation across different environments.

Applications:
Factory industrial automation often relies on pneumatic control circuits to enhance efficiency and precision in various processes. These systems are integral in industries such as manufacturing and packaging, where automated pneumatic solutions improve productivity.
Pneumatic technology is widely applied in machine tools, packaging machinery, and textile equipment. These applications benefit from the reliability and speed offered by pneumatic components, making them essential in high-speed production environments.
Robotic systems incorporate pneumatic actuators to control movement accurately. These loops often include mechanisms like cylinder back-flow prevention to ensure smooth and safe operation without unintended reversals.
To maintain optimal performance, components such as compressors, air dryers, and air preparation units require dedicated protection. Proper maintenance and safeguarding of these units helps extend their lifespan and prevents system failures.
Safety is paramount in pneumatic systems, especially concerning flexible air hoses. The use of safety devices, such as the T60 Air Fuse, is mandatory to protect against hose rupture, minimizing risk to both equipment and personnel.
Conveying equipment and material-handling systems frequently utilize pneumatic technology due to its cleanliness and efficiency. These systems streamline operations in various industries by providing reliable and controllable pneumatic power.
In automotive assembly lines and printing machinery, pneumatic systems play a crucial role. They offer consistent force and speed control, which is vital for precision assembly and printing tasks.
Vacuum pneumatic circuits, such as those from the T50P series, support applications requiring vacuum suction and control. These circuits enhance the capability of pneumatic systems, expanding their use in specialized industrial processes.
