What is the difference between VNA and VNB series general purpose fluid control 2/3-port valves?
-
VNA series valves are mainly for use with compressed air.
VNB series valves feature a water hammer relief structure (A to B flow), and the body and seal materials can be selected to accommodate a wide range of fluids such as water, oil, air, vacuum, etc.
Select a VNA series valve when the operating fluid is an inert gas and needs to flow in both directions (port 1 (A) to port 2 (B) and port 2 (B) to port 1 (A)) or when using an air-hydro circuit.
Select a VNB series valve when the operating fluid is an inert gas and 1-directional flow (A to B) is acceptable, when using water or oil as the fluid, or when using for low vacuum.
Note) For more information on applicable fluids, refer to the catalogs. The VNA series catalog can be found here. And the VNB series catalog can be found here.
