FESTO VMPA2-M1H-E-PI Directional Control Valve | 5/3 Exhausted, 20mm, 590 l/min, IP65 Specs

FESTO VMPA2-M1H-E-PI directional control valve specifications. 5/3-way exhausted center, 20mm valve size, 590 l/min flow rate, 24V DC, IP65 protection. For industrial automation and pneumatic control applications.

Product Overview

The FESTO VMPA2-M1H-E-PI​ is a 5/3-way directional control valve with exhausted center position​ from the VMPA2 series, designed for industrial pneumatic control applications. This model features a 20mm valve size, 590 l/min standard rated flow, 24V DC operation, and IP65 protection. The "E" designation indicates the specific valve function configuration (5/3-way exhausted center), while "M1H" specifies the mounting and connection type. This valve provides precise control of double-acting pneumatic cylinders with all ports exhausted to atmosphere in the center position, making it suitable for applications requiring cylinder free-floating or intermediate neutral positions.

Technical Specifications

Note: Specifications are based on FESTO VMPA2 series technical documentation. The "VMPA2-M1H-E-PI" model specifically indicates 5/3-way exhausted center function, 20mm size, and M1H mounting configuration. Actual specifications may vary slightly depending on production batch.

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

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

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

• E:​ Valve function (E = 5/3-way, exhausted center position)

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

Note:​ The "E" suffix indicates the 5/3-way exhausted center valve function. In the center position (de-energized state), all ports (1, 2, 3, 4, 5) are exhausted to atmosphere, allowing the cylinder to float freely. The "PI" designation typically refers to pilot operation characteristics.

Key Features

• 5/3-Way Function:​ Exhausted center position for cylinder floating applications

• High Flow Rate:​ 590 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:​ Detenting/non-detenting function for testing and maintenance

• Quick Response:​ Fast switching times (≤11 ms ON, ≤47 ms OFF)

• Wide Pressure Range:​ -0.9 to 10 bar operating range (including vacuum)

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

• Exhausted Center:​ All ports exhausted in center position for cylinder floating

Typical Applications

• Double-Acting Cylinder Control:​ Precise positioning with floating capability

• Industrial Automation:​ Machine protection and safety systems

• Material Handling:​ Workpiece clamping and positioning with neutral positions

• Assembly Systems:​ Component handling requiring cylinder floating positions

• Process Control:​ Pneumatic systems requiring intermediate neutral positions

• Test Equipment:​ Laboratory and production test setups with floating functions

• Robotics:​ End-of-arm tooling requiring free-floating positions

Important Technical Notes

1. Operating Pressure:​ Do not exceed 10 bar maximum operating pressure. Suitable for vacuum applications down to -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. Center Position Function:​ In de-energized state, all ports are exhausted to atmosphere. Ensure downstream equipment is designed for this condition.

9. 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.
