Festo On-off Valve 16 bar HE-1/4-D-MIDI 186513

Description

The Festo HE-1/4-D-MIDI is a high-quality, manually operated on-off valve, also known as a shut-off or start-up valve. It belongs to the D-series of air preparation components and serves as the primary means to pressurize and vent pneumatic systems safely. Its 3/2-way, normally closed function ensures that the system is depressurized when the valve is in the off position. The rotary knob is lockable, providing a crucial safety feature for maintenance and service work (lock-out/tag-out).

Is this valve suitable for vacuum applications?

No, the Festo HE-1/4-D-MIDI is designed for positive pressure applications from 0 to 16 bar. It is not rated for use in vacuum systems.
