Electro-pneumatic soft start and quick exhaust valve for gradual pressure control and rapid exhaustion of system components (one channel). The main flow control valve in the cover ensures a gradual build-up of output pressure p2. As soon as the output pressure p2 has reached the set pressure switching point (switching pressure), the valve opens and the full pressure p1 is then present on the output.
