3A200 Series 3 Port Air Operated Valve 3A210-08
1. Dopow pneumatic 3A200 series directional pilot control valves are 3 port 2 position spool valves.
2. Available port sizes are 1/8” 1/4” NPT with flow coefficients (CV) from 0.78 to 0.89.
3. These air operated valves are available with single pilot spring return or double pilot 2-position operation.
4. The 3A200 series can be used in individual pilot operated valve applications, or multiple valves can be field assembled on series manifolds for simplifying piping connections.
5. Structure in sliding column mode: good tightness and sensitive reaction
6. Double air control valves have memory function.
7. Internal hole adopts special processing technology which has little attrition fiction, low start pressure and long service life.
8. No need to add oil for lubrication.
