The VNA series is a universal 2 port valve used for controlling pneumatic systems or air-hydro circuits. Its balanced poppet design permits normal and reverse flow application.

To directly thread in the cylinder, use durable fittings (Stainless steel square nipples etc,) instead of ductile iron fittings (JIS B 2301) or steel pipe fittings (JIS B 2302). When VNA is installed away from the cylinder, use a high-pressure rubber hose (JIS B 6349) instead of steel pipe, when possible. 2. Air bleeding Series VNA valves have no air bleeding port.
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
