Product Model
hel-3/4-d-maxi

Key Features
- 1The Festo HEL-3/4-D-MAXI soft-start valve is designed for gradual pressure build-up and exhaust-air function, ensuring a controlled and efficient operation of pneumatic systems.
- 2This valve features a 2/2-way closed, monostable function, allowing for precise control over airflow and pressure.
- 3The valve is actuated pneumatically, providing a reliable and efficient method for controlling pneumatic connections.
- 4The HEL-3/4-D-MAXI includes a mechanical spring reset, ensuring the valve returns to its original position after each cycle, maintaining consistent performance.
- 5The valve is constructed with a soft sealing principle, ensuring minimal wear and tear, and is compatible with various thread sizes including G1/2, G3/4, and 3/4 NPT.
