Functional engineering application
The 4MATIC 4M-NAM-SA-32 is a specialized direct-acting 3/2-way normally closed pneumatic solenoid valve engineered for spring-return quarter-turn actuators. Unlike pilot-operated solenoid valves that require a minimum internal differential pressure (typically 1.5 to 2 bar) to shift the main spool, the 4M-NAM-SA-32 utilizes a direct magnetic armature to actuate the poppet seat directly. This allows the valve to operate reliably from 0 bar up to 8 bar. This zero-differential capability makes the 4M-NAM-SA-32 ideal for low-pressure pneumatic circuits, emergency shutdown (ESD) loops, and safety-critical spring-return valve assemblies where air header pressure may drop during plant upset conditions. The valve housing features a hard-anodized aluminium body with standard VDI/VDE 3845 NAMUR mounting geometry for seamless installation on all standard single-acting pneumatic actuators. An integrated manual override facilitates quick mechanical testing during commissioning.
Direct-acting 3/2-way NAMUR solenoid valve for spring-return single-acting actuators. Operates from zero differential pressure (0–8 bar) with rapid armature shifting and IP65 protection.

Common questions on this part
Internal pilot-operated valves require a minimum line pressure (usually 1.5–2 bar) to build pilot force. In applications where air supply pressure fluctuates or drops near zero, pilot valves can stall. The direct-acting 4M-NAM-SA-32 uses electromagnetic force to lift the seal directly, guaranteeing operation from 0 to 8 bar.
No. The 4M-NAM-SA-32 is a 3/2-way valve designed specifically for single-acting spring-return actuators. For double-acting actuators that require pressure to both open and close, select the 5/2-way 4M-AMV-NAM-220 or 4M-OTX-PPT.
