Norgren T55C3800 Inline Non-Return Valve - G3/8 Port
Part Number: T55C3800
Quick Summary
T55C3800 inline non-return valve ensures one-way air flow for compact pneumatic circuits in automation plants. In tight spaces, backflow and leaks can derail cycles and drive up maintenance costs. Standards like CE marking, IP ratings for protection, and SIL safety considerations are common in modern valve designs to help meet regulatory and safety requirements. With a silicone-free body and low cracking pressure, this valve minimizes contamination risk and supports reliable performance. Its 63 mm length, G3/8 port, and aluminium body suit compact installations, while compatibility with Pneufit C fittings speeds field assembly and ensures leak-tight connections across automated lines.

FAQs
The T55C3800 uses a G3/8 port and is compatible with Pneufit C fittings. Recommended options include C02471038 (90° swivel elbow, 10 mm, G3/8) and C02251038 (straight, 10 mm, external/internal hex). Pair these with PA2 tubing options PA2-0010025C (25 m) or PA2-0010100 (100 m) for reliable, leak-tight assemblies.
Operating pressure range is 0.1 to 10 bar (1.45 to 145 psi). Operating temperature spans -20 to 80 °C (-4 to 176 °F), making it suitable for typical plant air conditions and many automated environments.
Yes. It provides one-way flow control with a compact G3/8 port, aluminium body, and silicone-free construction, which helps prevent backflow, reduces contamination risk, and fits into tight automation spaces while enabling quick field installation with standard Pneufit C fittings.
Certification details are not listed in the provided data. For regulatory alignment, consult the datasheet and verify CE marking, IP protection levels, and SIL considerations as applicable to your safety and compliance requirements. The datasheet is available from Norgren for authoritative confirmation.
A silicone-free body minimizes silicone oil contamination in the air stream, reducing residue on downstream components and improving reliability. Combined with a low cracking pressure design, it supports consistent performance with reduced maintenance intervals in clean or precision pneumatic applications.
