Function section symbol

GeneralThe pressure valve type MHDBNY02 is a pilot operated pressure relief valve for installation in block designs It is used for system pressure limitation The system pressure can be set steplessly via the adjustment type (4)

Pressure relief functionThe valve is closed in initial position The pressure in main port ① acts on the spool (1) At the same time pressure is applied to the spring-loaded side of the spool (1) via nozzle (2) and to the pilot poppet (6) via nozzle (3) If the pressure in main port ① exceeds the value set at spring (5) the pilot poppet (6) opens Hydraulic fluid flows from the spring-loaded side of the spool (1) via the nozzle (3) and channel (7) into the external port ③ The resulting pressure drop moves the spool (1) and thus opens the connection from main port ① to ② while maintaining the pressure set at the spring (5) The pilot oil return is effected externally via the channel (7) to the external port ③The pressure applied to port ③ is added to the pressure value set at the spring (5) in a ratio of 11

Feed functionThe feed function makes up for lacking oil volumes caused for example by leakage when pressure valves respond and in the case of leading loads If the pressure at main port ① is lower than that at main port ② the spool (1) will be lifted out of its seat Hydraulic fluid flows from main port ② to main port ① Tank preloading should be ge 4 bar

Notice The cracking pressure depends on the counter

return flow pressure at main port ② The pilot operated pressure valves are virtually

leakage-free thanks to their design

Technical data (for applications outside these values please consult us)

1) The cleanliness classes specified for the components must be adhered to in hydraulic systems Effective filtration prevents faults and simultaneously increases the life cycle of the components

Available filters can be found at wwwboschrexrothcomfilter We recommend using a filter with a minimum retention rate

of szlig10 ge 752) Rexroth standard test condition (HLP46 ϑoil = 40 degC plusmn 5 degC)

Notice Under application conditions with an operating pressure of lt 30 bar and a flow of lt 30 lmin valves of another design are to be selected from our valve program The maximum operating pressure is the sum of the set pressure and counter pressure

The technical data was determined at a viscosity of v = 41 mm2s (HLP46 ϑoil = 40 degC)

Function section symbol

GeneralThe pressure valve type MHDBNY02 is a pilot operated pressure relief valve for installation in block designs It is used for system pressure limitation The system pressure can be set steplessly via the adjustment type (4)

Pressure relief functionThe valve is closed in initial position The pressure in main port ① acts on the spool (1) At the same time pressure is applied to the spring-loaded side of the spool (1) via nozzle (2) and to the pilot poppet (6) via nozzle (3) If the pressure in main port ① exceeds the value set at spring (5) the pilot poppet (6) opens Hydraulic fluid flows from the spring-loaded side of the spool (1) via the nozzle (3) and channel (7) into the external port ③ The resulting pressure drop moves the spool (1) and thus opens the connection from main port ① to ② while maintaining the pressure set at the spring (5) The pilot oil return is effected externally via the channel (7) to the external port ③The pressure applied to port ③ is added to the pressure value set at the spring (5) in a ratio of 11

Feed functionThe feed function makes up for lacking oil volumes caused for example by leakage when pressure valves respond and in the case of leading loads If the pressure at main port ① is lower than that at main port ② the spool (1) will be lifted out of its seat Hydraulic fluid flows from main port ② to main port ① Tank preloading should be ge 4 bar

Notice The cracking pressure depends on the counter

return flow pressure at main port ② The pilot operated pressure valves are virtually

leakage-free thanks to their design

Technical data (for applications outside these values please consult us)

1) The cleanliness classes specified for the components must be adhered to in hydraulic systems Effective filtration prevents faults and simultaneously increases the life cycle of the components

Available filters can be found at wwwboschrexrothcomfilter We recommend using a filter with a minimum retention rate

of szlig10 ge 752) Rexroth standard test condition (HLP46 ϑoil = 40 degC plusmn 5 degC)

Notice Under application conditions with an operating pressure of lt 30 bar and a flow of lt 30 lmin valves of another design are to be selected from our valve program The maximum operating pressure is the sum of the set pressure and counter pressure

The technical data was determined at a viscosity of v = 41 mm2s (HLP46 ϑoil = 40 degC)

The following documentation must be observed 64020-B1 Hydraulic valves for mobile applications
