Valve terminals type 32 MPA
Key features – Pneumatic components
Sub-base valve
MPA offers a comprehensive range of
valve functions. All valves are
equipped with piston spool and pat-
ented sealing system which facilitates
efficient sealing, a broad pressure
range and long service life. To in-
crease power they have a pneumatic
pilot control supplied by pilot air.
Sub-base valves can be quickly
replaced since the tubing connectors
remain on the manifold block.
This design is also particularly flat.
Irrespective of the valve function there
are sub-base valves with one solenoid
coil (single solenoid) or with two
solenoid coils (double solenoid or two
single solenoid valves in one
housing).
Constructional design
Valve replacement
Extension
The valves are attached to the metal
manifold block using two screws,
which means that they can be easily
replaced. The mechanical sturdiness
of the manifold block guarantees
excellent long-term sealing.
Blanking plates can be replaced by
valves at a later date. The dimensions,
mounting points and existing pneu-
matic installations remain unchanged
during this process.
The valve code (M, J, N, NS, K, KS, H,
HS, B, G, E, X, W, D, DS I) is located on
the front of the valve beneath the
manual override.
