Norgren T70C1800 Quick Exhaust Valve - G1/8, Zinc Body
Part Number: T70C1800
Quick Summary
The T70C1800 quick exhaust valve enables rapid air release in pneumatic automation across manufacturing lines. When exhaust is slow, cylinders stall, bottlenecking speeds, cycle times, and overall throughput. This valve aligns with common industry standards such as CE safety requirements, SIL in safety-related controls, and IP-rated rugged housing to protect against harsh environments. Its compact zinc alloy body and nitrile seals deliver reliable operation, with easy retrofits and long service life. By reducing exhaust time and simplifying maintenance, it supports higher line productivity while lowering lifecycle costs and improving system reliability.

FAQs
Plan for standard G1/8 fittings and manifolds; ensure correct orientation to avoid dead zones in exhaust lines; verify compatible mounting hardware and seals, and confirm the valve is integrated with an appropriate air preparation unit. Use the provided CAD data to validate space and clearance before final mounting.
By venting pressure quickly, the valve reduces cylinder dwell time, enabling faster advance and retraction. Its 0.5–10 bar operating range and -20 to 80 °C suitability support stable, repeatable exhaust across diverse tooling speeds, contributing to measurable gains in throughput and reduced cycle times.
Yes. It is well-suited for high-speed manufacturing, automotive assembly, packaging lines, and automation cells requiring rapid exhaust and compact form. The G1/8 port and compatible nitrile seals make it a drop-in option for many Norgren T70 configurations and standard pneumatic manifolds.
Certification specifics depend on regional configurations. Refer to the datasheet for CE considerations and any site-specific approvals. For safety-critical or hazardous environments, confirm IP rating and SIL-related compliance with your system integrator and local regulations.
The valve’s simple, robust design lowers maintenance frequency while enabling faster cycle times, improving throughput. The zinc body and nitrile seals resist typical industrial contaminants, reducing leakage and service interventions. Combined with widely available CAD assets, this supports rapid design-in and lower total cost of ownership.
