In-line excess flow control is the core feature, delivering a fast response that stops unintended air flow when pressure spikes occur. The business impact is safer processes and reduced risk of pneumatic damage, especially in automated tooling and pick-and-place lines. In practice, engineers install it on G1/2 ports to safeguard compressed-air circuits in manufacturing cells where tight flow control matters. Tamper-proof and compact design enhances security and space savings. The business impact is lower risk of unauthorized adjustments and easier integration into tight machine footprints. Application examples include CNC machines, packaging lines, and robotic cells where cabinet-mounted valves must stay protected and unobtrusive. Automatic reset after fault conditions minimizes downtime by returning to production-ready state without manual intervention. This translates to higher line uptime, lower maintenance costs, and more predictable outputs. It is particularly effective in continuous-flow lines like conveyors and pneumatic clamping systems. High corrosion resistance provided by aluminium body ensures longevity in humid environments or contact with lubricants. This reduces replacement cycles and warranty exposure, yielding lower cost of ownership. Suitable for outdoor or factory floors with exposure to contaminants where aluminium bodies perform well. Low pressure drop across the valve improves overall system efficiency and reduces energy consumption in high-flow circuits. In practice, this means less compressor work, quieter operation, and longer tool life in demand-driven applications. Broader operating range -20 to 80 C and 0 to 16 bar makes it compatible with many industrial air systems. The T60 range integrates smoothly with existing Norgren components for streamlined installation and spare-part compatibility across an automation library. Designed under the IMI Norgren brand with reliable performance and supply chain support, this valve fits teams focusing on safety, compliance, and total cost of ownership.

FAQs
Install the T60C4891 on a compatible G1/2 port with clean, dry compressed air. Ensure correct orientation for flow direction, tighten fittings to the manufacturer’s torque spec, and verify the 0-16 bar operating range is suitable for the circuit. After mounting, test for leaks and confirm automatic reset functionality under simulated fault conditions to ensure immediate return to service.
Key performance parameters include an operating pressure range from 0 to 16 bar (0 to 232 psi), a flow capability of 0.39 dm3/sec, and an operating temperature range of -20 to 80 °C (-4 to 175 °F). These specs support reliable operation in typical factory air systems while accommodating moderate environmental variability.
The T60C4891 excels in automation cells, robotic gripping and clamping stages, CNC and packaging lines, and other safety-critical pneumatic circuits where excess flow must be quickly isolated. Its compact, tamper-proof design makes it suitable for both cabinet-mounted installations and inline configurations in harsh manufacturing environments.
Certification considerations typically include regulatory safety standards and industry best practices for pneumatic components. Verify the datasheet for specific CE conformity statements, IP ratings if applicable, and any SIL or functional-safety claims. Cross-check installation guidelines, materials, and environmental compatibility to ensure full regulatory alignment for your plant.
The automatic reset feature minimizes downtime after a fault, reducing maintenance labor and production interruption. The aluminium body offers corrosion resistance and longer service life in demanding environments, lowering replacement frequency. Combined with a compact footprint and low pressure drop, this valve supports total cost of ownership reductions in systems with frequent start-stop cycles.
