HEL-D-MIDI
Product Overview
Festo HEL-D-MIDI (Part No.170691) belongs to HEL D series modular soft-start valve, MIDI size for air service unit combination. It slowly charges pressure to pneumatic circuit, the main valve opens at around 50% inlet pressure, pressure rising speed can be adjusted by built-in flow restrictor. Effectively prevent sudden jump of cylinders or actuators when system starts up, commonly combined with HE / HEE cut-off valve in compressed air preparation assembly.
