Norgren T55C1800 In-line non-return valve - G1/8
Part Number: T55C1800
Quick Summary
The Norgren T55C1800 in-line non-return valve provides unidirectional airflow control for compressed air systems in automation and manufacturing. Engineers often battle leaks, variable cracking pressure, and silicone contamination that disrupts reliable pneumatic lines. In typical industrial projects, industry standards such as CE compliance, SIL reliability concepts, and IP-rated protection are commonly referenced; this valve supports those expectations through a rugged aluminum body and compact form, with exact ratings available in the datasheet. Designed for compact spaces, it delivers dependable one-way flow while minimizing maintenance, enabling faster assembly and lower operational costs.

The compact G1/8 port design and aluminium body enable space-saving installation in crowded panels and compact manifolds. This combination reduces enclosure footprint and simplifies retrofits, allowing higher valve density without compromising performance in tight automation racks. In practical automation, a small, robust inline non-return valve supports reliable one-way flow, boosting line efficiency and maintenance predictability. Silicone-free construction minimizes contamination risk across pneumatic lines, translating to cleaner actuation and longer service intervals in precision assemblies. This is valuable where residue can affect valve seating, downstream sensors, or co-located seals, reducing unplanned downtime. Designers gain confidence knowing the valve aligns with cleanability and compliance expectations, while reducing calibration needs in dynamic lines. Operating range of 0.1 to 10 bar and -20 to 80 °C supports a wide spectrum of equipment, from robotics to clamps. The aluminium body resists corrosion in humid or dusty factories, maintaining performance and reducing replacement costs. G1/8 connections streamline integration with existing manifolds and push-in fittings, and 6 mm tubing supports rapid prototyping. Low cracking pressure delivers fast response in short-cycle applications, improving cycle times and energy efficiency during rapid actuation. Paired with Pneufit C push-in fittings and 6 mm tubing, installation is straightforward, leak-tight, and less error-prone. Lightweight at 0.015 kg minimizes mounting loads on small manifolds, aiding vibration-prone environments and easier retrofits. The T55 family is widely used in automation, offering predictable behavior across conveyors, presses, and assembly cells. Its 42.5 mm length and 15 mm width enable compact stacking in modular rails, with durable aluminium construction. Aligning with Norgren's broader portfolio simplifies spare parts, maintenance planning, and lifecycle reliability for OEMs and system integrators.

FAQs
The T55C1800 uses G1/8 port size and is compatible with Pneufit C push-in fittings listed in the product data, including C02470618 and C02250618. It supports 6 mm tubing from the PA2 family. For installation, ensure clean, dry compressed air, proper mounting, and secure tubing connections to maintain leak-tight performance in compact panels.
The valve tolerates 0.1–10 bar (1.45–145 psi) and operating temperature from -20 to 80 °C (-4 to 176 °F). This broad range supports most industrial pneumatic circuits while maintaining reliable flow direction. Ensure you stay within these limits to avoid backflow or reduced performance.
Yes, the inline design offers fast response with low cracking pressure, minimizing backflow hesitation in rapid cycling applications. The aluminium body provides durability in compact form, supporting reliable operation in pick-and-place lines, conveyors, and other high-speed automation environments.
Yes. CAD resources are available via the product page and CAD portals, and the Datasheet (PDF) provides full specs, operating ranges, and installation guidelines. Use these files to verify compatibility with your existing pneumatic circuit and to ensure correct orientation and sealing during integration.
The silicone-free design minimizes residue, reducing contamination risk in sensitive lines, while the unidirectional flow prevents back pressure and leakage. Coupled with easy push-in fittings and a compact footprint, you can shorten assembly time, lower maintenance visits, and improve system uptime in automated production lines.
