SMCSYJ514-5LOUD-Q3-Port Normally Closed Pilot Solenoid Valve, Base Mounted, Rc1/8 Sub-Plate, 24 V DC, 0.55 W

Product Description

What this part is

SMC SYJ514-5LOU-Q pilot-operated solenoid valve from the SYJ5000 series. A pilot-operated valve uses a small solenoid to switch pilot air, and that pilot air throws the main spool, which is what lets a 0.55 W coil control a full working flow. Manufacturer: SMC. Part Number: SYJ514-5LOU-Q. Series: SYJ5000. Ways and Positions: 3-port, 2-position. Operation: normally closed, solenoid and spring return. Mounting: base mounted. Port Size: Rc1/8 with sub-plate. Coil Voltage: 24 V DC. Power Consumption: 0.55 W. Operating Pressure: 0.15 to 0.7 MPa. Maximum Flow Rate: 245.38 NL/min. Operating Temperature: -10 °C to +50 °C. Seal Type: rubber seal.

Decoding the designation

SYJ5 — SMC’s SYJ5000 solenoid valve series.

SYJ51 — the three-port body within that series.

4 — base mounted.

5 — 24 V DC coil.

L — L-type plug connector electrical entry.

Q — the copper-free execution.

SYJ5145LOUDQ and SYJ514-5LOU-Q are the same part number, unpunctuated and punctuated.

What these specs mean in practice

Ways and Positions: 3-port, 2-position, normally closed. Three ports means supply, output and exhaust: the valve fills a single-acting cylinder, an air spring or a vacuum pad, and vents it on de-energising. Operating Pressure: 0.15 to 0.7 MPa. A pilot-operated valve needs the 0.15 MPa minimum to throw its own spool, and 0.7 MPa is the working ceiling. Power Consumption: 0.55 W. Half a watt is inside the direct drive current of a standard PLC output card, so the valve wires straight to an output without an interposing relay. Maximum Flow Rate: 245.38 NL/min. Seal Type: rubber seal. Rubber-seal construction gives a tighter shutoff and a lower leak rate than a metal-seal spool. Operating Temperature: -10 °C to +50 °C. The valve carries a non-locking manual override for commissioning and an individual pilot exhaust, and is built to the copper-free specification for use around display and semiconductor processes.

Mounting data

Mounting: base mounted. Port Size: Rc1/8 with sub-plate. A base-mounted valve bolts to a sub-plate or a manifold block that carries the pipe threads, so the pipework stays in place when the valve is swapped.

Quantity and configuration

Unit Quantity: 1 Pc. One complete valve per listing.

Interchange guidance

SYJ5145LOUDQ and SYJ514-5LOU-Q are the same part number. Within the SYJ5000 range the digits before the electrical code fix the port count and the mounting, and the letters after it fix the coil, connector and material execution. SYJ5143-5LOU-Q and SYJ514M-5LOU-Q are catalogued siblings on the same 24 V DC, L-plug, copper-free specification.
