Valve terminals MPA-L

Key features – Pneumatic components

Sub-base valve

MPA-L offers a comprehensive range

of valve functions. All valves are

equipped with piston spool and

patented sealing system that

facilitates efficient sealing, a broad

pressure range and long service life.

They have a pneumatic pilot control

for optimising performance.

Air is supplied by means of pilot air

supply.

Sub-base valves can be quickly

replaced since the tubing connectors

remain on the sub-base.

This design is also particularly slim.

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).

Design

Valve replacement Extension

The valves are attached to the

sub-base using two screws,

which means that they can be easily

replaced. The mechanical sturdiness

of the sub-base guarantees good

long-term sealing.

Blanking plates can be replaced by

valves at a later date. The dimensions,

mounting points and existing

pneumatic installations remain

unchanged during this process.

The valve code (e.g. M, J, N, NS, NU,

etc.) is located on the front of the

valve beneath the manual override.

-H- Note

A filter must be installed upstream of

valves operated in vacuum mode.

This prevents any foreign matter in

the intake air getting into the valve

(e.g. when operating a suction cup).
