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.
