SMC 10-SY7440R-5MZ-03 | Clean Room 5-Port Solenoid Valve SY7000 Series Base Mounted Double Solenoid Rubber Seal 3/8" NPT High Flow

The SMC 10-SY7440R-5MZ-03 is a clean room specification 5-port solenoid valve from the SY7000 series with rubber seal and double solenoid configuration. Part number decoded: SY7440 = SY7000 series type 440 (5-port double solenoid, specific internal configuration), R = rubber seal, 5MZ = solenoid specification (5 = voltage, M = coil type, Z = auto-switch groove), 03 = 3/8" NPT port size. The SY7000 is the largest valve body in the SY series family, providing maximum flow capacity.

The SY7000 delivers the highest Cv (flow coefficient) in the SY series, approximately 2-3x the flow of the SY3000 and 1.5x the SY5000. The 3/8" NPT ports complement the large valve body, eliminating port-side flow restriction. This high-flow capability is essential for large-bore clean room cylinders (50mm+ bore), high-speed cycling applications where fast fill/exhaust determines cycle time, and systems with long tube runs where pressure drop must be minimized. The double solenoid configuration maintains last-position memory during power loss.

The SY7440R-5MZ-03 is the top-of-line SY single valve for high-flow clean room applications. For single solenoid spring return at SY7000 flow, the SY7140R provides fail-safe retraction. For the next step down in flow, the SY5240R (SY5000) reduces valve size. For manifold mounting of multiple SY7000 valves, the SS5Y7 series provides bar stock base assemblies. For even higher flow beyond the SY7000, consult SMC for VF series or process valve alternatives. Clean series (10-) fluorine grease, Particle Grade 1. RoHS compliant.
