Norgren T74T-3GA-P1N Valve - Excelon 3/2, G3/8
Part Number: T74T-3GA-P1N
Quick Summary
The Norgren T74T-3GA-P1N valve provides compact Excelon 3/2 shut-off control for pneumatics in automated lines. Installers often face misalignment and high stiction when moving from inline to modular configurations. Certification details such as CE, SIL or IP ratings are not provided in this data set, but the Excelon platform is built for reliable operation in busy production environments. With a G3/8 port and a lockable closed position, it reduces changeover time and helps maintain process consistency. The zinc body and nitrile elastomers deliver durable sealing in compressed air circuits while supporting scalable, low-maintenance automation. This combination supports engineering teams seeking reliable, cost-effective control across multiple lines.

Excelon Plus 3/2 modular system shut-off valve, G3/8
Excelon 3/2 modular system design enables both in-line installation and modular integration with other Excelon products, reducing installation time and integration risk. This approach simplifies panel plumbing, aligns valve actuation across a product family, and minimizes rework during line upgrades. In practice, engineers deploy the same valve platform on conveyors, pick-and-place cells, and packaging stations, delivering consistent performance while accelerating commissioning and reducing spare-parts inventory. The G3/8 port size and the compact 74 mm height with 70 mm width and length support tight panel layouts and streamlined exhaust routing through the 1/8 inch threaded port. This geometry enables quicker positioning and easier mounting in crowded control cabinets, lowering installation labor and simplifying service access for maintenance and future expansions. Low stiction operation means rapid, reliable actuation with minimal pilot effort. That reduces cycle times and wear on upstream and downstream components, delivering measurable efficiency gains in high-cycle systems such as bottling lines and automated assembly. For engineers, this translates to lower energy consumption and less downtime, even when switching between different product lines. Lockable in the 'closed' position enhances safety and prevents unintended actuation during setup, testing, or maintenance. This is particularly valuable in multi-valve manifolds where cross-communication can cause unsafe states. The design supports safer changeovers and greater process control, helping meet operational safety practices while preserving quick access to the valve for service. Durable construction combines a zinc body with nitrile elastomer seals to resist wear, corrosion, and small leaks in compressed air circuits. The operating range of -34 to 65 °C, plus a maximum inlet pressure of 17 bar, ensures reliable performance across typical plant environments. With a 3/2 valve operation and 116 dm3/sec flow, it delivers predictable actuation for medium- to high-demand applications in manufacturing. This combination supports engineering teams seeking reliable, cost-effective control across multiple lines.

FAQs
The T74T-3GA-P1N is designed for both inline mounting and modular integration within the Excelon family. Its G3/8 port and standard 3/2 operation ensure consistent actuation across modules, reducing manifold complexity and enabling quick line upgrades. For procurement and maintenance teams, this means fewer part numbers to stock and faster deployment across multiple lines.
Key specs include a compressed air medium, operating temperature from -34 to 65 °C (-30 to 149 °F), port size G3/8, maximum inlet pressure of 17 bar, 3/2 valve operation, flow 116 dm3/sec (246 scfm), zinc body, and nitrile rubber elastomers. The valve weighs 0.32 kg and is designed for reliable actuation in demanding automation environments.
Best suited for automated lines, packaging equipment, conveyors, and robotics where inline and modular Excelon installations are advantageous. Its compact footprint and 1/8" exhaust port simplify panel layout, while the low-stiction action supports high-cycle use cases with consistent performance and reduced maintenance needs.
Use the appropriate seals and mounting hardware for a zinc-bodied valve with nitrile elastomer seals. Mount to maintain proper alignment, utilize the 1/8" exhaust port for clean routing, and avoid over-torquing. Ensure correct operating pressure does not exceed 17 bar and confirm the panel space accommodates the 74 mm height by 70 mm width footprint.
Lockable closed position enhances safety during setup and maintenance, preventing unintended actuation and reducing unscheduled downtime. This feature supports safer changeovers in multi-valve manifolds and improves process control, contributing to lower maintenance costs, longer component life, and a quicker return on investment for automation projects.
