4A220-08 Air Pilot Valve Double Pilot 5 Port 2 Position 1/4in NPT CV=0.89
4A200 Series Air Pilot Valve
1. Structure in sliding column mode: good tightness and sensitive reaction.
2. Three position air valves have three kinds of central function for your choice.
3. Double air control valves have memory function.
4. Internal hole adopts special processing technology which has little attrition fiction, low start pressure and long service life.
5. No need to add oil for lubrication.
6. Integrate with the manifold to save installation space.
