<p>Pneumatic non-return valves are one of the simplest types of pneumatic valves available. They allow compressed air to flow in one direction and prevent or block it from flowing in the opposite direction. Also known as a check valve these simple but effective devices help to eliminate any potential damage that may be caused by backflow pressure. RS offer a range of high-quality valves from leading brands including Festo, SMC, Legris, Norgren and of course RS PRO.</p><h2>How does a Pneumatic Non-Return Valve Work?</h2><p>Non-return valves work automatically, which means that most valves don&rsquo;t need human intervention external control to work. The valves will have two openings or ports, an inlet and an outlet port. An internal spring will lift when the pressure upstream is great enough to overcome the tension of the spring. This is referred to as the &lsquo;cracking pressure&rsquo;.</p><h2>What is Cracking Pressure?</h2><p>Cracking pressure refers to the minimum pressure differential needed between the inlet and outlet of the valve at which the first indication of flow occurs. When cracking pressure is reached, the valve will open to allow flow, when it drops the valve will close.</p><h2>What are the different types of Pneumatic Non-return valve?</h2><p>Pneumatic non-return valves are available in two main types. Push in tube-to-tube or Push-in tube to threaded.</p><p><strong>Tube-to-Tube Non Return Valves</strong></p><p>This type of non-return valve will have a push-in connection port at either end. They are available with different body materials, including brass and aluminium. Hose sizes ranging from 4 mm to 12 mm</p><p><strong>Tube to Threaded Non Return Valves</strong></p><p>This type of non-return valve will have a tube connection on one end and a threaded connection on the other. They are available with different body materials including brass and aluminium. Hose sizes ranging from 4 mm to 12 mm. Threads are typically BSPP (G), BSPT (R), NPT, and Metric.</p>

<p>Browse our selection of pneumatic non-return valves from IMI Norgren and establish simple and effective single-direction air flow in your compressed air system.</p><p>This type of valve is designed to allow air to flow in one direction only, preventing backflow pressure which could otherwise cause damage to the pneumatic system. They are also known as check valves and tend to be small and lightweight, with a simple design. They are an important protective component in air systems.</p><h2>How do they work?</h2><p>Non-return valves work automatically and feature a ball or diaphragm, or sometimes are spring assisted. These devices have two openings: an inlet port and an outlet port. When cracking pressure occurs (where the inlet pressure exceeds outlet pressure) the valve will open, allowing air flow.</p><p>Norgren's S520 series units are heavy-duty valves which have a reliable design and can handle high operating pressures, ranging from 0.3 to 16 bar. They feature a durable brass body and can be operated in temperatures of -20°C to +80°C, making them suitable for use in demanding industrial environments.</p><p>The T50P series Norgren pneumatic valves have an aluminium body, low weight, and low cracking pressure of 0.03 to 0.05 bar. They use seals comprised of silicon-free nitrile, providing resistance to abrasions and fluids such as oil and water, and high tensile strength.</p><p>The C00GL Pneufit C models use nickel-plated brass components which offer excellent corrosion resistance, for a longer life. These units are ready-to-use, allowing quick and easy installation with no need for tools.</p>
