SMCVX2120015DZ1B2-Port Direct Operated Solenoid Media Valve, Rc1/8, 2 mm Orifice, Cv 0.23, 24 V DC, IP65

Product Description

What this part is

SMC VX2120-01-5DZ1-B direct-operated two-port solenoid valve from the VX21 series. A direct-operated valve lifts its seat with the solenoid force alone, so it opens and closes with no minimum pressure differential across the port. Manufacturer: SMC. Part Number: VX2120-01-5DZ1-B. Series: VX21. Ways and Positions: 2-port, 2-position. Operation: direct operated. Port Size: Rc1/8. Orifice: 2 mm. Flow Coefficient: Cv 0.23. Effective Area: 5.5 x 10−6 m². Maximum Operating Pressure Differential: 1.0 MPa. Coil Voltage: 24 V DC. Power Consumption: 4.5 W. Enclosure: IP65. Weight: 300 g.

Decoding the designation

VX2 — SMC’s direct-operated two-port media valve family for air, gas, vacuum, water, steam and oil.

VX21 — the single-unit body of the family, as against the VX22 and VX23 sizes.

2 — the size 1 body with a 2 mm orifice.

01 — Rc1/8 port size.

5 — 24 V DC coil.

VX2120015DZ1B and VX2120-01-5DZ1-B are the same part number, punctuated and unpunctuated.

What these specs mean in practice

Operation: direct operated. Because the solenoid does all the work of lifting the seat, the valve shuts and opens down to zero pressure differential, which is what lets it serve vacuum lines and gravity-fed water as well as pressurised air. Orifice: 2 mm. Flow Coefficient: Cv 0.23. That is a metering-scale flow: a small, controlled passage rather than a bulk supply port. Maximum Operating Pressure Differential: 1.0 MPa, which is 145 psi. Coil Voltage: 24 V DC. Power Consumption: 4.5 W. Enclosure: IP65. An IP65 body is dust-tight and withstands low-pressure water jets from any direction, and the housing conforms to UL94V-0 flame resistance. The VX21 family is built so that body material, seal material and coil class are all selectable, which is why one series covers air, inert gas, vacuum, water, steam and oil.

Mounting data

Port Size: Rc1/8, inlet and outlet. Weight: 300 g. The VX21 single unit is a threaded in-line valve and drops into an Rc1/8 pipe run; the same body is also offered on a manifold base.

Quantity and configuration

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

Interchange guidance

VX2120015DZ1B, VX2120-01-5DZ1-B and VX2120 01 5DZ1 B are the same part number. Within the VX21 series the digits before the port code fix the orifice and flow, and the digits after it fix the coil and electrical entry, so VX2120-01 siblings carrying a different electrical suffix share this valve’s Rc1/8 porting, 2 mm orifice, Cv 0.23 and 1.0 MPa differential rating. The VX2120-02N is the same valve body with 1/4 NPT porting.
