SMC VH432-04 5/3 Solenoid Valve | 3-Position, 5-Port, 1/4" NPT, 24V DC, 4W Specs

SMC VH432-04 pneumatic solenoid valve specifications. 3-position, 5-port, center closed, 1/4" NPT, 24V DC, 4W coil. For double-acting cylinder control.

Product Overview

The SMC VH432-04​ is a three-position, five-port (5/3) pneumatic solenoid valve​ from SMC's VH series, designed for precise control of double-acting cylinders. This model features a center closed configuration, 1/4" NPT ports, operates on 24V DC, and consumes 4W power. The "VH432-04" designation identifies this specific 3-position valve configuration. This valve provides accurate mid-position control for applications requiring cylinder stopping, holding, or precise positioning, commonly used in automation, machine tools, and material handling equipment.

Technical Specifications

Note: Specifications are based on SMC VH series documentation. The "VH432-04" typically indicates 1/4" NPT, 24V DC configuration. Actual performance may vary with system conditions.

Model Number Decoding (VH432-04)

• VH:​ Series designation (VH series 3-position valve)

• 432:​ Model code (5/3-way, center closed, specific spool design)

• 04:​ Configuration code (1/4" NPT, 24V DC, standard coil)

Note:​ The "VH432" indicates the 3-position, 5-port valve type. The "-04" suffix typically specifies 1/4" NPT ports and 24V DC coil. Other suffixes indicate different port sizes and voltages.

Key Features

Important Technical Notes

1. Sub-base Required:​ This valve requires a separate sub-base​ (SMC SY or SZ series) for mounting and port connections. The valve itself has no ports.

2. Center Position Behavior:​ In center position (both solenoids de-energized), all ports are blocked. The cylinder will hold position if there is no load or leakage.

3. Double Solenoid Operation:​ Both solenoids are momentary. A continuous signal must be applied to maintain the valve in either A or B position. The valve returns to center when both solenoids are de-energized.

4. Air Quality:​ Use clean, lubricated or non-lubricated compressed air. If using non-lubricated air, do not add lubricant later. Filter to 40 µm, remove moisture.

5. Electrical Protection:​ Use surge suppressors or diodes for inductive load protection. Follow local electrical codes for wiring.

6. Manual Operation:​ Use manual override for setup and troubleshooting. Ensure machine safety when using manual override.

7. Cylinder Holding:​ While the center closed design holds position, external stops or brakes may be needed for high-load applications due to cylinder seal leakage.

8. Flow Capacity:​ Ensure Cv value (1.0) is adequate for your cylinder size and required speed. Larger cylinders or higher speeds may require valves with higher flow capacity.
