Overview Pressure-limiting valve type MV.., SV.., DMV.. Pressure-limiting valves are a type of pressure valve. They safeguard the system against excessive system pressure or limit the operating pressure. Sequence valves generate a constant pressure difference between the inlet and outlet ow. The types MV.., SV.., DMV.. are directly controlled valves that are damped as standard. Features and advantages ■ Operating pressures up to 700 bar ■ Various adjustment options ■ Numerous configurations Intended applications ■ General hydraulic systems ■ Test benches ■ Hydraulic tools Pressure-limiting valve...

3.1 General data Design Directly controlled pressure valve, in ball seated design MV: Zinc die casting: Standard version for normal operating cases MVS, MVCS: Spheroidal casting: For rough operating conditions. For systems where mechanical shocks or vibrations are unavoidable (vehicle construction). Also in the case of pressure surges in the return line. MVE, MVP, SV, DMV, DMVN, MVT, SVC: Steel Surface protection Steel parts and spheroidal casting, electrogalvanised, spring dome made from zinc die casting, untreated depending on the type, freely hanging in the pipeline or attached over through...

3.3 Characteristic lines Viscosity of the hydraulic uid approx. 50 mm2/s Characteristic curve shown based on the example of MV..C (basic trend, certain differences are present depending on the pressure gradient and depending on the housing shape of the various basic types). The characteristic lines change to positive Sp values in the event of increased return pressure. Size 4

Flow direction R d P with type MVC.. and SVC.. Size 4 Size 5 Size 6 NOTICE Inherent ow resistance in the event of relieved spring (static pressure value 0 bar). Pressures below this boundary are not achievable, see Chapter 3.3, "Characteristic lines" Pressure change Rough reference values (for the closed valve) per 1 revolution on the adjusting screw Pressure (bar) Travel fmax (mm) / Sp (bar) per 1 revolution Size 4 Values in brackets apply for type SV and SVC NOTICE Pressure adjustment only with monitoring of the pressure gauge, see Chapter 6.1, "Setting instructions" HAWE Hydraulik
