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