General
GENERAL Valve system
PVG 100 is a hydraulic load sensing valve, designed to fulfill customer requirements. From a simple load sensing directional valve to an advanced electro hydraulic controlled load independent proportional valve. The PVG 100 modular system makes it possible to build up a valve group to fulfill customer requirements. The compact external dimensions of the valve remains unchanged whatever combination is specified.
General features PVG 100
• Load independent flow control
• Oil flow to an individual function is independent of the load on this function
• Oil flow to one function is independent of the load pressure of other functions
• Anti – saturation (flow sharing)
•
In case of anti saturation, pump flow is shared between all functions, independent of load.
• Good regulation characteristics
• Up to 8 PVB 100 basic modules per valve group
• Up to 10 PVB 100/32 basic modules per valve group
• BSP and UNF connection threads
PVP - Pump side module
• Build in load sense relief valve
• System pressure up to 350 bar (5075 psi) • Accumulator gauge connection
• Full Flow dump valve (open center only) • Pressure gauge connection
• Pilot supply shut off • Pilot gauge connection
• Versions
• Open center version for systems with fixed displacement pumps
• Closed center versions for systems with variable displacement pump
• Integrated priority valve
• Integrated pilot supply valve
PVB – basic module
• Integrated pilot operated check valves in A and B work ports for low internal leakage
• Integrated pressure compensator
• Interchangeable spools
• Depending on requirements the basic module can be supplied with :
• Shock/suction valves
• Different spools
Actuation modules
The basic module is always fitted with mechanical actuator PVM, which can be combined with the following as required:
• Electrical actuator
• PVES – super proportional
• PVEH – proportional high
• PVED – Can-bus interface
• PVEA – proportional, fine
• PVEO – ON/OFF
• PVH, cover for hydraulic actuation
• PVMD, for mechanical actuation
• PVMR, for friction detent
• PVMF, for mechanical detent, float
Function PVG 100
PVG 100 VALVE GROUP WITH OPEN CENTER PVPF
When the pump is started and the main spools in the individual basic modules are in the neutral position, oil flows from the pump, through connection P, across the pressure matching spool to tank. The oil flow led across the pressure matching spool determines the pump pressure (stand-by pressure). When one or more of the main spools are actuated, the highest load pressure is fed through the shuttle valve circuit to the spring chamber behind the pressure matching spool, and completely or partially closes the connection to tank. Pump pressure is applied to the opposite side of the pressure matching spool. The pressure relief valve will open should the load pressure exceed the set value, diverting pump flow back to tank.
In a pressure-compensated basic module the compensator maintains a constant pressure drop across the main spool – both when the load changes and when a module with a higher load pressure is actuated.
Besides independent flow the other advantage of post-compensated work sections is the ability to control multifunction operation when flow demand exceeds pump capacity. This means that all work sections will continue to function regardless of differences in their load and regardless of the pump flow. The flow relationships specified between functions will be maintained over the full flow range of the pump.
The shock valves PVLP with fixed setting and the suction valves PVLA on ports A and B are used for the protection of the individual working function against overload and/or cavitation.
PVG 100 VALVE GROUP WITH CLOSED CENTER PVPV
In load sensing systems the load pressure is led to the pump regulator via the LS connection. In the neutral position the pump control sets the displacement so that leakage in the system is compensated for, to maintain the set stand-by pressure. When a main spool is actuated the pump regulator will adjust the displacement so that the set differential pressure between P and LS is maintained. The pressure relief valve in PVP should be set at a pressure of approx. 30 bar [435 psi] above maximum system pressure (set on the pump or external pressure relief valve).
With post-compensated valves, the rating of the A- and B work-port flow will depend on the pressure drop across the main spool PVBS. In open center systems, this pressure drop (standby-pressure) is generated by the volume of pump flow led to tank across the pressure adjusting spool in the inlet PVPF. Since the pressure drop varies with pump flow volume led to tank, also the A- and B work-port flow will vary (see further details page 19).
In closed center systems, the pressure drop across the main spool equals the standby setting of the pump, measured at the P-port of the valve. The A and B work port flow will remain unchanged as long as the standby is unchanged.
