IMI Norgren S/511 Quick Exhaust Valve - Aluminium Body
Part Number: S/511
Quick Summary
The S/511 Quick Exhaust Valve from IMI Norgren delivers rapid air venting for compact pneumatic systems. Engineers often struggle with slow exhaust that limits cylinder speeds and drives cycle times in automated lines. Designed for industry use, it supports CE-compliant installations in regulated markets and offers robust performance over -20 to 80 C and 0.7 to 10 bar, with an aluminium body and polyurethane seals. CE-compliant design supports European installations and IP-rated assemblies when integrated into certified manifolds. Combined with its compact form and reliable polyurethane seals, it minimizes maintenance and boosts throughput. For engineers evaluating total cost of ownership, the S/511 offers predictable performance and easy integration with G1/2 ports.

FAQs
Install the S/511 by aligning the G1/2 port with the manifold adapter, securing with appropriate fittings, and ensuring the aluminium body is correctly oriented for exhaust flow. Use polyurethane seals to maintain airtight performance and check that the mounting surface is clean and flat to avoid leaks. Tighten to the recommended torque specs and verify operation with a brief cycle test.
The S/511 excels in rapid exhaust of air from reservoirs and cylinders, accelerating return strokes and increasing cycle rates. It is well-suited for high-speed pick-and-place, clamping cycles, and other pneumatic actuation tasks where fast venting reduces overall cycle time and improves throughput in automated manufacturing.
