4A400 includes single-pilot 4A410 and double-pilot 4A420 5/2 valves, plus double-pilot 4A430C/E/P 5/3 valves. All main inlet, outlet and exhaust ports are 1/2; pilot ports are separately 1/8. Retain the full circuit code and installed interface for replacement inquiries.
No. 4A400 uses port code 15: inlet, outlet and exhaust are 1/2. The installation drawings show pilot connections separately as 1/8. Match the actual connection and PT/G/NPT thread.
48.0 mm² / Cv 2.82 is listed for 4A410-15 and 4A420-15; 40.0 mm² / Cv 2.35 specifically for 4A430C-15. E/P flow values are not stated. Maximum no-load frequency is 3 cycles/s for both 5/2 and 5/3.
Yes. Send the label or photos, circuit function, quantity and destination. Official P124 lists 400M for 4A400 with 1–8 stations and a 1/2 base inlet. Send occupied stations, thread and blank-plate needs for a base or valve-assembly quotation.
