High Pressure Non Return Valve S/524 IMI Norgren G1 Inch Thread Brass Inline Check Valve For Air Compressor System

Product Description:

IMI Norgren non-return valves are high-quality inline one-way pneumatic components engineered to allow compressed air to flow freely in one direction while effectively preventing any reverse back-flow within pneumatic systems. This product range 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 series features a durable brass body designed to perform reliably under high-pressure industrial conditions of up to 16 bar. These valves come with G or NPT thread options and also include a high-temperature variant capable of withstanding temperatures up to +150°C, with FPM seals ensuring enhanced thermal resistance.

The T50P valves utilize a quick-connect push-in tube connection, compatible with outer diameter tubes ranging from 4 to 12 mm. These valves can operate under vacuum conditions as low as -0.9 bar and feature an ultra-low cracking pressure between 0.03 and 0.05 bar. Designed for convenience, they allow for fast and straightforward field assembly without the need for thread sealing.

Constructed from lightweight aluminum, the T55 inline non-return valve is silicone-free and offers a low cracking pressure of just 0.05 bar. Its compact size makes it suitable for installations with limited space constraints. This valve supports working pressures up to 10 bar, with 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 air flow when a hose rupture or significant leakage occurs, then resets automatically once the fault has been resolved. This valve is specifically designed to provide safety protection for flexible hoses, ensuring compliance with industrial pneumatic safety standards.

All Norgren non-return valves are intended for use with filtered compressed air, whether lubricated or non-lubricated. They are rigorously tested according to the ISO-6358 standard and are widely implemented in factory automation pneumatic circuits to ensure reliable performance.

Features:

The product offers multiple series options to accommodate various needs, including heavy-duty threaded models such as the S/520 to S532 series, push-in types like the T50P, the compact T55, and the safety air-fuse model T60.

It operates efficiently across a wide pressure range, from a vacuum of -0.9 bar up to a maximum of 16 bar, ensuring versatility in different applications.

With a low cracking pressure starting at just 0.03 bar, this product ensures minimal resistance during opening, promoting smooth and efficient flow control.

Diverse connection types are available, including G and NPT threaded options, along with push-in tube connections compatible with outer diameters between 4 mm and 12 mm, providing flexibility for various system setups.

The construction materials include brass and aluminium bodies, paired with NBR seals as standard. For high-temperature environments, optional FPM seals are available to enhance durability and performance.

The temperature operating range spans from -20℃ to +80℃ under standard conditions, with the S-series offering an optional extension up to +150℃ for high-temperature applications.

The T60 Air-Fuse model incorporates a hose-burst protection feature with an auto-reset function and tamper-proof safety design, ensuring reliable safety during operation.

Installation is straightforward with a simple inline line-mount setup. The compact structure delivers high reliability and a long service life, making maintenance easy and reducing downtime.

The product is compatible with filtered compressed air, inert gases (specifically for the T60), and can handle both lubricated and non-lubricated air, broadening its range of uses.

Applications:

Industrial automation within factories heavily relies on pneumatic control circuits to ensure efficient and reliable operation. These systems are integral to a wide range of machinery including pneumatic machine tools, packaging machines, and textile equipment.

In robotic applications, pneumatic actuators play a crucial role. Specific features such as cylinder back-flow prevention are essential to maintain the performance and safety of the pneumatic loops driving these actuators.

Protection of key components like compressors, air dryers, and air preparation units is vital for the longevity and stability of pneumatic systems. Safety mechanisms, including flexible air-hose rupture protection, are mandatory — with devices such as the T60 Air Fuse being essential in such applications.

Pneumatic systems are widely utilized in conveying equipment and material handling solutions. Additionally, sectors such as automotive assembly lines and printing machinery heavily depend on specialized pneumatic circuits for smooth operation.

Vacuum pneumatic circuits, for example those from the T50P series, are also employed in various industrial processes, providing reliable vacuum generation and control within pneumatic setups.
