Description of main components

- Pressure regulator: The Class C pressure regulator provides compensation for pressure fluctuations in

the supply network.

This ensures a constant air flow with a constant step rate and

constant nozzle pressure.

- Safety valves: As per EN161, Class B/C

- Dirt trap: Fine-mesh strainer at the inlet to protect the fitting against particles and other dirt

- Safety valve operating modes: The double safety valves V1 and V2 are designed for mutually independent closing

and are jointly actuated and opened.

- Pressure test nipple: On inlet side
