Norgren M/1704/687 Valve - 5/3 Actuation with G1/2
Part Number: M/1704/687
Quick Summary
Norgren M/1704/687 Valve is a compact, air-operated 5/3 valve for automated pneumatic control in manufacturing lines. Downtime and misalignment during servicing are common bottlenecks, especially with sub-base mounting that extends machine idle time. This range aligns with standard industrial safety expectations and robust design practices, typically supporting CE compliance and SIL/IP-rated configurations across process and packaging environments. By combining a compact footprint with an air-assisted detent for precise valve location and simple servicing, it enables faster installation and reduced maintenance costs, while sub-base mounting minimizes downtime in changeovers. The zinc body and nitrile seals withstand harsh factory conditions, and the 2–10 bar operating range covers most plant air systems.

FAQs
Yes. The M/1704/687 is designed for sub-base mounting and uses standard G1/2 ports, enabling straightforward integration with Pneufit C fittings (C02471248 and C02251248). Its compact zinc body with nitrile seals tolerates typical factory environments, and the lever/spring/lever actuation plus a simple service procedure minimize downtime during changeovers for faster commissioning and predictable operation.
Key performance specifications include medium: compressed air; port size: G1/2; actuation: lever/spring/lever; valve operation: 5/3; flow: 3200 l/m; operating temperature: -20 to 80 °C; operating pressure: 2 to 10 bar. The unit weighs 2.4 kg and measures 200 x 200 mm with a 50 mm height. Built-in nitrile seals on a zinc body support durable, long-life service.
Yes. It’s well suited for automated packaging and pneumatic control tasks where reliable detent positioning and quick changeovers matter. The air-assisted detent provides positive valve location, while the sub-base mounting simplifies panel integration. The 3200 l/m flow supports actuation of common packaging actuators, and the 2–10 bar range accommodates typical plant air systems.
Certification specifics should be checked in the product datasheet. Norgren Martonair ranges are designed for industrial use and commonly align with CE marking and safety standards, with IP-rated variants available for harsher environments and SIL safety considerations in critical processes. Always verify the exact certification scope for your region and application in the Datasheet (PDF) linked on the product page.
ROI benefits come from reduced downtime due to easy servicing and reliable valve location, lower maintenance costs from durable nitrile seals and zinc construction, and space savings from sub-base mounting. The 2–10 bar operating range and 3200 l/m flow support efficient cycle times, improving OEE and throughput over older, larger valves while enabling quicker commissioning and fewer field adjustments.
