3.4.3

Vacuum/low-pressure operation

Note

If valves are used for switching a vacuum, filters must be used in the suction line to

avoid malfunctions caused by foreign matter sucked into the line.

The 2x 2/2-way valves with ident. code D, I and the 2x 3/2-way valves with ident.

Code N, K, H are not suitable for vacuum or low pressure operation (–0.9 … 3 bar).

If you supply the valve terminal with operating pressure between (–0.9 … 3 bar) via

port (1):

Operate the above-mentioned valves in a separate pressure zone.

Set

the

operating pressure for this pressure zone in accordance with the diagram

(

Appendix A, Fig. A.2)

The following requirements must be fulfilled in order to operate your valve terminal at the supply

port (1) with an operating pressure between –0.9 ... 3 bar:

– The pilot control is operated with regulated external pilot air supply die (pilot pressure

Appendix A, Fig. A.1, Fig. A.2).

– The valve terminal must be equipped only with the following valves and, if necessary, have additional

pressure zones.

Pressure zone supply via port
(1)

Applicable valve

Pressure zone with an operating

pressure between

–0.9 … 3 bar

– 5/2-way valve, monostable (ident. code M and MS)

– 5/2-way bistable valve (ident. code J)

– 5/3-way valves (ident. code B, E and G)

– 2x 3/2-way valves (ident. code HS, KS and NS)

– 3/2-way valve (ident. code W and X)

– 2x 2/2-way valve (ident. code DS)

Pressure zone with operating

pressure > 3 bar

– All above valves

– 2x 3/2-way valves (ident. code H, K and N)

– 2x 2/2-way valves (ident. code D and I)

The valves with ident. code D, H, I, K and N are

not

suitable for vacuum or low-pressure operation!

Tab. 3.2

Valves for vacuum and low pressure operation

Valve with ident. code W and X, 3/2-way valve:

– These valves are supplied individually, independent of the supply port (1).

– The valves can be operated in the range of –0.9 … 8 bar.

– The pilot air is supplied through the valve terminal.

– The ports via which these valves are supplied with compressed air or vacuum and via

which exhaust air is removed are shown in Tab. 3.3.
