Directly controlled pressure limiting and sequence valves type MV, SV etc.


	Nomenclature:	Pressure limiting valve,
		sequence valves
	■	(directly controlled) ■
	1 Design:	■ Individual valve for
		pipe connection

		Individual manifold
		mounting valve
	■	Assembly kit ■
	Adjustability:	1 Tool adjustable
	■	Manually adjustable ■
	I Pmax^: ■	1 700 bar

Pressure valves gover the pressure within a hydraulic system. The types below are intended for the following purposes:

• Pressure limiting valve (safety valve):

Safeguarding the system against excessive pressure or for the limitation of working pressure.

• Sequence valves:

Generates a constant pressure difference between inlet and outlet of the flow.

Directly controlled valves feature a dampening device to ensure quiet operation, but they are also available without it if necessary for an application. There is also a version of the pressure limiting valve (Type MV.X), conforming the Pressure Equipment Directive 97/23 EC, which features a type approval and a CE-stamping, usually necessary when used as safety valves for accumulators.
