The VN series is a combination of process valves that can be operated with pressure differential zero and comes with many variations. The VNA series is used for controlling pneumatic systems or air-hydro circuits. The VNB series controls various fluids. VNC is used for controlling the cutting oils and coolants used in machine tools. VNH is for controlling high pressure cutting oils and coolants

Do not use standard dew point 40C (symbol: L) type, standard dew point 60C (symbol: S) type and IDG30A, 50A, 30HA, 50HA for dehumidifying breathing air. Do not use only outlet air (dry air) in a closed room. 1. Consider the purge air flow rate. Find the purge air flow rate from the charts and calculate the required outlet air flow rate + purge air flow rate.
