Airtac 400M Solenoid Valve Manifold Base 400M8F
The AirTAC 400M Solenoid Valve Manifold Base 400M8F is a genuine 400M valve manifold base with 8 valve stations. It feeds every station from one PT1/2 inlet and collects the exhausts, so a bank of 4A400 air pilot and 4V400 / 5V400 solenoid valves runs off a single supply line instead of 8 separate drops.

About the Airtac 400M Solenoid Valve Manifold Base 400M8F
The 400M8F is the largest standard base in AirTAC's 400M manifold range, carrying the full eight stations that a 400-body valve bank can hold. One 1/2 inch common inlet feeds every station instead of running a separate air drop to each valve, so a big bank needs one shut-off, one set of fittings and a single collected exhaust point rather than eight of each. The bar is 306 mm long overall on a 294 mm mounting pitch, figures you need before committing panel space.
The PT (Rc tapered) thread version seals on the thread flanks, so wrap the inlet with PTFE tape and torque it home - unlike a parallel G port, which seals at the face on a bonded washer. The base accepts both valve families of the 400 body: 4A400 air-pilot valves and 4V400 / 5V400 solenoid valves can sit side by side on the same row, so a pilot-operated section and an electrically controlled section can share one supply.

Length and pitch follow the official AirTAC 400M dimension table: A = 61 mm for one station plus 35 mm per extra station, giving 306 mm at 8 stations. Overall HEIGHT is not listed here because it depends on which valve you fit - a solenoid 4V/5V valve stands taller than an air-pilot 4A on the same base.

How a Manifold Bank Goes Together
- check One PT1/2 inlet feeds every station, so you run a single supply drop.
- check Each station takes one 400-body valve; the A and B work ports stay on the valve.
- check Exhausts collect in the base — silence the bank once instead of per valve.
- check Any station you are not using yet takes a P-400M-R2 blank plate.
- check Station seals are a serviceable part: P-400M-R1.
Where the Airtac 400M Solenoid Valve Manifold Base 400M8F Is Used
Injection moulding ejection bank
An injection moulding machine's ejection and core-pull valves can sit on one 306 mm rail fed by a single 1/2 inch drop, replacing eight individual supply runs behind the guard.
Pneumatic truck body controls
A truck-mounted tipper or walking-floor body typically clusters five to eight large valves; one PT inlet and one collected exhaust keep the chassis plumbing short and serviceable.
Palletiser clamp circuit
Clamp and position cylinders on a palletising cell draw from one 400M8F base, so a single lockout valve de-energises the whole fixture bank at shift change.
Is the Airtac 400M Solenoid Valve Manifold Base 400M8F the Right Part?
Eight stations is the maximum the 400 body offers, so the 400M8F is the end of the line for expansion - there is no longer base to grow into later. If the bank is likely to gain valves, that is a reason to buy it now; if not, the 7 station 400M7F at 271 mm overall (264 mm pitch) saves 35 mm of rail. Match your supply fittings to PT / Rc tapered and keep PTFE tape at every inlet joint.
Sizing check before ordering: the 1/2 inch common inlet and the 1/2 inch station ports set the bank's flow ceiling together with the valves fitted, so confirm the valves, not the base, carry the flow your cylinders need. Air to the base should be filtered through a 40 um element, and the temperature envelope is -20 to +70 C.
Quick checklist
- ✓ Valve body size (400) matches the base
- ✓ Station count — allow spares for later
- ✓ Panel space for 306 mm of length
- ✓ Mounting holes at 294 mm pitch
- ✓ Thread standard (PT)
Airtac 400M Solenoid Valve Manifold Base 400M8F FAQ
It is an 8 station manifold base for 400-body valves - the maximum station count for that body. Overall length A is 306 mm (61 + 35 x 7), mounting pitch KA is 294 mm (49 + 35 x 7). The common inlet is 1/2 inch and each station port is 1/2 inch, on PT (Rc tapered) threads. It carries both 4A400 air-pilot valves and 4V400 / 5V400 solenoid valves. Fluid is air filtered by a 40 um element, temperature -20 to +70 C.
No - eight stations is the largest base the 400 body comes in, so this code already uses the full length and there is nothing left to blank. The usual strategy of buying a longer base and closing spare stations with a P-400M-R2 blank plate only applies below the maximum; if you need that route, look at a 400M base with fewer stations plus blank plates for the unused ones.
