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 industrial applications.
The first group, the heavy-duty brass series S/520-S/532, features a robust brass body constructed for high-pressure industrial environments with working pressures up to 16 bar. These valves come with G or NPT thread options and also offer a high-temperature variant capable of operating at up to +150°C, utilizing FPM seals for enhanced durability.
The T50P series consists of push-in non-return valves that utilize a quick-connect tube connection designed for outer diameter tubes ranging from 4 to 12 mm. These valves support vacuum conditions down to -0.9 bar, boast an ultra-low cracking pressure between 0.03 and 0.05 bar, and enable fast, simple field assembly without the need for thread sealing.
The T55 inline non-return valve is a lightweight, silicone-free check valve with an aluminium body. It features a low cracking pressure of 0.05 bar and a compact design suitable for installations with limited space. This valve operates at pressures up to 10 bar and is available with port sizes ranging from G1/8 to G1/2.
Lastly, the T60 Air Fuse is a specialized uni-directional excess-flow shut-off safety valve. It automatically cuts off air flow in the event of hose rupture or significant leakage and resets automatically once the fault is cleared. This valve is intended for flexible hose safety protection and complies with industrial pneumatic safety standards.
All Norgren non-return valves are designed for use with filtered compressed air, whether lubricated or non-lubricated. They are rigorously tested according to the ISO-6358 standard, making them widely adopted in factory automation pneumatic circuits.
Features:
Our product line offers multiple series options to suit various applications. These include the heavy-duty threaded S/520-S532 series, the push-in T50P model, the compact T55, and the safety air-fuse T60.
Designed to operate within a wide pressure range, these devices can function effectively from a vacuum level of -0.9 bar up to a maximum pressure of 16 bar, ensuring versatility across different systems.
The low cracking pressure feature, starting at just 0.03 bar, allows for a minimal flow-resistant opening. This ensures high sensitivity and efficient operation in your pneumatic setups.
Connectivity is diverse, with options including G or NPT threaded connections as well as push-in tube fittings for outer diameters ranging from 4 to 12 millimeters, providing flexibility in installation.
Material choices are tailored to your needs, featuring brass or aluminium bodies along with NBR seals. For higher temperature requirements, optional FPM high-temperature seals are also available.
The standard operating temperature range is from -20℃ to +80℃. Additionally, the S-series models offer an optional extended high-temperature rating of up to +150℃, suitable for more demanding environments.
The T60 Air-Fuse model provides exceptional safety features including hose-burst protection, automatic reset capability, and a tamper-proof design, ensuring reliable operation and enhanced safety.
Installation is straightforward with a simple inline line-mount design. The compact structure, combined with high reliability, contributes to a long service life, reducing maintenance needs.
These devices are compatible with filtered compressed air and inert gases (specifically for the T60 series) and support both lubricated and non-lubricated air media, making them highly adaptable.

Applications:
Industrial automation in factories often relies on pneumatic control circuits to enhance efficiency and precision. These systems play a crucial role in the operation of various machinery and processes by utilizing compressed air to power different components.
Pneumatic technology is widely applied in machine tools, packaging machines, and textile equipment. Its versatility allows these machines to perform complex tasks with reliability and speed, making it an essential part of modern manufacturing.
In robotic applications, pneumatic actuators form important control loops. Features such as cylinder back-flow prevention ensure smooth and safe operation of these robotic systems, contributing significantly to their performance and longevity.
Protection of key pneumatic elements is vital for maintaining system integrity. Components like compressors, air dryers, and air preparation units require specialized safeguards to prevent damage and extend their service life.
Safety measures also include flexible air-hose rupture protection. The mandatory use of devices like the T60 Air Fuse provides an essential safety layer that helps avoid accidents caused by sudden hose failures in pneumatic systems.
Pneumatic systems are also extensively used in conveying and material handling equipment. These setups manage the movement of goods efficiently within manufacturing and assembly environments, enhancing workflow productivity.
Additional applications include automotive assembly lines and printing machinery, where pneumatic controls contribute to consistent and accurate operation, ensuring product quality and process reliability.
Specialized vacuum pneumatic circuits, such as those in the T50P series, offer advanced capabilities for specific industrial needs, providing precise control and improved system performance in various applications.
