Features
• Spool type valve
• Subplate mounting acc. to ISO 5781
• 5 pressure stages at NG06
• 3 pressure stages at NG10
• 2 adjustment modes
Direct operated pressure reducing valve with manual
adjustment. Series VM is a direct-controlled, spring
loaded 3 way pressure reducing valve, that is open in
neutral position. The valve closes the connection when the
pre-set pressure is exceeded.
Primary port: NG06 -P, NG10 - B
Secondary port: NG06 - A, NG10 - A
Tank port: NG06 - T, NG10 - Y
If the pressure increases due to an external influence
the spool opens to port T until the pre-set pressure is
reached.
