Operation of the MPA−S valve termina l with reversible
pressure regulat ors (Ident. code PN, PM, PL, PK):
· No 2x2/2−way valves with Ident. code D, I or 2x3/2−way
valves with Ident. code N, K, H (non−reversible valves) may
be operated with these pressure regulators.
· Reversible pressure regulating valves must not be used on
reve rsibly operated valve terminals.
3.4.4 Setting the pressure regulating valve
The pressure regulator plates can be set using the following
operator control elements:
For size MPA2, using the adjusting knob or the adjusting
screw.
Note
For the A and B pressure regulator plates of type
VMPA...B8−R...C2−C−... (ident code: PH, PG, PC, PB),
thecontrol pressure should not be below 2 bar.
Forcontrolpressures below 2 bar, use the reversible
AorB pressure regulating valves (identifier in the type
code: PN, PM, PL, PK) see Tab.1/10.
