Helpful for Model Matching:

  • Full 4STA code or readable label
  • 10 single-pilot NC/NO; 20 double-pilot without NC/NO
  • 100:M5/06;200:06/08;300:08/10; no verified400 size
  • Thread, separate1/8 pilot port and matching4STV base
  • Select single-pilot10 or double-pilot20 drawing; NC/NO applies only to10.
  • Match the exact size/port dimension row; pilot ports separately1/8.
  • 100/200/300 have dedicated4STV manifold sizes; compare installed station count and blank plates.

Avoid a wrong match

  • Do not omit NC/NO on10 or add NC/NO to20.
  • M5 has no PT/G/NPT suffix; all main and exhaust ports share the selected size.
  • Official ordering/specification covers100/200/300 only. A400 label needs separate confirmation.
  • Request4STV100M/200M/300M, not4SV bases for4SA or standard4A/3V bases.
  • Base diagram lists1F–30F but dimension tables cover1F–20F: confirm larger assemblies.

Read the model code

If the label is incomplete, send the readable parts together with a photo.

About 4STA

4STA100/200/300 are three-port two-position valves with external air pilot. 10 is single-pilot, with NC normally closed or NO normally open. 20 is double-pilot and uses no NC/NO code. Match size, state, all main ports, pilot connection, thread and 4STV base.

Matching Questions

Do single and double air-pilot codes both use NC/NO?

No. Single-pilot10 requires NC or NO; double-pilot20 uses neither suffix. Send an ambiguous code or label for confirmation.

Which ports and sizes belong to4STA?

The ordering table covers100:M5/06,200:06/08 and300:08/10. Inlet,outlet and exhaust share the chosen size; pilot connections are separately1/8. A 400 size is not listed in the ordering table.

Which manifold base should I request?

Match4STA100/200/300 to4STV100M/200M/300M. Ordering stations1F–30F; printed dimensions1F–20F. Send valve code,station count,thread,blank plates,quantity and destination; confirm larger assemblies.
