FESTO VMPA2-M1H-W-PI Directional Control Valve | 3/2 NC, 20mm, 470 l/min, IP65 Specs

FESTO VMPA2-M1H-W-PI directional control valve specifications. 3/2-way normally closed, 20mm valve size, 470 l/min flow rate, 24V DC, IP65 protection. For industrial automation and pneumatic control applications.

Product Overview

The FESTO VMPA2-M1H-W-PI​ is a 3/2-way normally closed directional control valve​ from the VMPA2 series, designed for industrial pneumatic control applications. This model features a 20mm valve size, 470 l/min standard rated flow, 24V DC operation, and IP65 protection. The "W" designation indicates the specific valve function configuration (3/2-way normally closed, single solenoid), while "M1H" specifies the mounting and connection type. This compact, metal-housed valve provides reliable switching for compressed air systems in automation equipment, material handling, and process control applications.

Technical Specifications

Note: Specifications are based on FESTO VMPA2 series technical documentation. The "VMPA2-M1H-W-PI" model specifically indicates 3/2-way NC function, 20mm size, and M1H mounting configuration. Actual specifications may vary slightly depending on production batch.

Model Number Decoding (VMPA2-M1H-W-PI)

• VMPA2:​ Series designation (VMPA2 directional control valve series)

• M1H:​ Mounting and connection type (M1H = specific mounting configuration with M8 electrical connector)

• W:​ Valve function (W = 3/2-way normally closed, single solenoid)

• PI:​ Additional options (PI = specific configuration details, typically indicating pilot type or other features)

Note:​ The "W" suffix indicates the specific valve function configuration. Other letters in this position (such as J, K, E, etc.) would indicate different valve functions (5/2-way, 5/3-way, etc.). The "PI" designation typically refers to pilot operation characteristics.

Key Features

• 3/2-Way Function:​ Normally closed configuration for single-acting cylinder control

• High Flow Rate:​ 470 l/min standard rated flow for rapid response

• Compact Design:​ 20mm valve size for space-constrained installations

• Metal Housing:​ Die-cast aluminum construction for durability

• IP65 Protection:​ Dust-tight and water-jet resistant for industrial environments

• LED Status Indicator:​ Visual indication of valve switching status

• Manual Override:​ Push-button with locking function for testing and maintenance

• Quick Response:​ Fast switching times (≤13 ms ON, ≤22 ms OFF)

• Wide Pressure Range:​ -0.9 to 10 bar operating range

• Standard Connections:​ M8 electrical connector and G1/8 pneumatic ports

Typical Applications

• Industrial Automation:​ Control of single-acting pneumatic cylinders

• Material Handling:​ Workpiece clamping and release systems

• Packaging Machinery:​ Air control for packaging equipment

• Assembly Systems:​ Component positioning and fixturing

• Process Control:​ Pneumatic valve control in manufacturing processes

• Test Equipment:​ Laboratory and production test setups

• Robotics:​ End-of-arm tooling control

Important Technical Notes

1. Operating Pressure:​ Do not exceed 10 bar maximum operating pressure. For vacuum applications, minimum pressure is -0.9 bar.

2. Pilot Pressure:​ Ensure pilot pressure is within 3-8 bar range for proper operation.

3. Electrical Connection:​ Use 24V DC power supply. Ensure correct polarity (reverse polarity protected).

4. Pneumatic Connections:​ Use appropriate sealing (PTFE tape or sealant) on G1/8 threads. For push-in fittings, use 8mm OD tubing.

5. Air Quality:​ Use filtered compressed air according to ISO 8573-1:2010 standards. Lubricated air can be used but requires continuous lubrication once started.

6. Mounting:​ Can be mounted in any position. Avoid excessive vibration or shock.

7. Temperature Limits:​ Operating temperature range is -5°C to +50°C. Do not use outside this range.

8. Maintenance:​ Periodically check for leaks and proper operation. Clean pneumatic ports if clogged.

Note: For complete installation guidelines, dimensional drawings, and detailed technical data, consult the official FESTO VMPA2 Series Technical Manual. Always verify the exact model number configuration with the manufacturer, as notation variations may occur.
