2 Catalogue HY11-5/UK Introduction Chapter : Proportional DC Valves Introduction: Proportional DC Valves Proportional valves and servo proportional valves are characterized by a number of design features that determine their quality to fit into different applications. The main features are listed below. Solenoid drive (proportional valves): Solenoids operate unidirectionally against a spring, provide high force and are - because of high inductance - limited in their dynamics. Voice Coil Drive : A moving coil in the field of a static permanent magnet operates bi-directionally. Springs are only needed to ensure the power-down position. The low inductance allows highest dynamics. External electronics: Valves without integrated electronics are less sensitive to vibration and high temperature. LVDTs always include integrated electronics. Integrated electronics (onboard electronics - OBE): Onboard electronics simplifies the installation and improves the repeatability from valve to valve. LVDT (spool position feedback): Closed loop control of the spool position improves the sensitivity and accuracy. Direct operated (d.o.): High hydraulic output can be achieved with low electric power input. Pilot operated (p.o.): Beyond the functional limits of direct operated valves hydraulic amplification is required. Positive spool overlap: To avoid load drifting in the zero position, spools with positive overlap are used. Zero lap spools: In closed loop circuits zero lap spools are used for an effective control of the spool at low position errors. Spool/Sleeve design: For minimal hysteresis, high precision, and better wear resistance, the spool/sleeve design is preferred over the spool/body design. Regenerative Valves: In applications with differential cylinders it is common to feed the return flow from the rod side of the cylinder back to the piston side to achieve higher velocity or lower pump flow. Parker differentiates between regeneration to the pressure level of the pump (P-regeneration) or directly to the piston area respectively the A-port of the valve (A-regeneration). The Parker regenerative valves use the advantageous A-regeneration. Hybrid Valves: Regenerative valves with an integrated solenoid valve - to switch to the standard mode - are called Hybrid Valves at Parker. The regenerative mode is used for maximum velocity, the standard mode for maximum force. Regenerative and hybrid valves are also available as on/off directional control valves. Intro.indd RH

3 Catalogue HY11-5/UK Characteristics Direct Operated Proportional DC Valve Series D1FB The proportional directional valves D1FB (NG6) are available with and without onboard electronics (OBE). D1FB OBE: The digital onboard electronics is situated in a robust metal housing, which allows the usage under rough environmental conditions. The nominal values are factory set. The cable connection to a serial RS22 interface is available as accessory. D1FB for external electronics: The parameters can be saved, changed and duplicated in combination with the digital power amplifier PWDA-4. The valve parameters can be edited with the common ProPxD software for both versions. The D1FB valves can be ordered with spool/sleeve design (D1FB*) for maximum precision as well as spool/body design (D1FB*) for high nominal flow - see functional limit curves for maximum flow capability.

34 Catalogue HY11-5/UK Characteristics The pilot operated proportional directional valves D*1FB are available in 4 sizes: D1FB - NG1 (CETOP 5) D41FB - NG16 (CETOP 7) D91FB - NG25 (CETOP 8) D111FB - NG2 (CETOP 1) The valves are available with and without onboard electronics (OBE). D*1FB OBE The digital onboard electronics is situated in a robust metal housing, which allows the usage under rough environmental conditions. The nominal values are factory set. The cable connection to a serial RS22 interface is available as accessory. D*1FB for external electronics The parameters can be saved, changed and duplicated in combination with the digital power amplifier PWDA-4. The valve parameters can be edited with the common ProPxD software for both versions. The D*1FB valves work with barometric feedback of the main stage to the pressure reducing pilot valve. The pilot control pressure of 25 bar allows high flow rates at maximum stability. The innovative integrated regenerative function into the A- line (optional) allows energy saving circuits for differential cylinders. The hybrid version can be switched between regenerative mode and standard mode at any time. Valves with explosion proof solenoids EEx me ll see catalogue HY11-4.

66 Catalogue HY11-5/UK Characteristics Pilot Operated Proportional DC Valve Series D*1FE The series of pilot operated proportional valves D*1FE is designed for high precision applications that require a safe middle position of the main spool at power down. The pilot is a -position valve with an overlapped middle position. This ensures that the main stage spring pushes the spool into the middle position at power down without an unintended jerk of the actuator. The D*1FE series is available in 5 sizes: D1FE NG1 (CETOP 5) D41FE NG16 (CETOP 7) D81FE NG25 (CETOP 8) for port diam. up to 26 mm D91FE NG25 (CETOP 8) for port diam. up to 2 mm D111FE NG2 (CETOP 1) The innovative integrated regenerative function in the A-line (optional) allows new energy saving circuits with differential cylinders.

77 Catalogue HY11-5/UK Characteristics Direct Operated Proportional DC Valve Series D1FP The direct operated control valve D1FP of the nominal size NG6 (CETOP ) shows extremly high dynamics combined with maximum flow. It is the preferred choice for highest accuracy in positioning of hydraulic axis and controlling of pressure and velocity. Driven by the patented VCD actuator the D1FP reaches the frequency response of real servovalves. Compared with solenoid driven valves the D1FP can also be used in applications with pressure drops up to 5 bar across the valve. Because of the high flow capability the D1FP can be a substitute for NG1 valves in some cases. At power-down the spool moves in a defined position. All common input signals are available.

94 Catalogue HY11-5/UK Characteristics The series of pilot operated servo proportional valves D*1FP transfers the advantages of the Parker patented Voice Coil Drive (VCD ) to larger frame sizes and thus high flow rates. The high dynamics / high precision drive of the pilot valve allows the optimum control of the main spool and results in servo class performance of the complete valves. The D*1FP series is available in 5 sizes: D1FP NG1 (CETOP 5) D41FP NG16 (CETOP 7) D81FP NG25 (CETOP 8) for port diam. up to 26 mm D91FP NG25 (CETOP 8) for port diam. up to 2 mm D111FP NG2 (CETOP 1) The safety concept works with a safe 4th position at the D1FP pilot valve. This ensures that the main stage is hydraulically balanced at power down and allows to have the main spool spring centered (for overlapped spools) or approximately 1 % spring offset to spool position A or B (for zerolap spools). The innovative integrated regenerative function into the A-line (optional) allows new energy saving circuits for differential cylinders. The hybrid version can be switched between regenerative mode and standard mode at any time. Technical features High dynamics High flow Defined spool positioning at power-down - optional P-A/B-T or P-B/A-T or center position (for overlapped spools) Onboard electronics Energy saving A-regeneration Switchable hybrid version D41FPE52 (Standard) Pilot Operated Servo Proportional DC Valve Series D*1FP D41FP Standard a A B P T A-regeneration D*1FPR b G G Further literature about the opportunities of energy savings and more functional details of the integrated regeneration is available on request. a A B P T Standard D*1FPE a A B P T Hybrid D*1FPZ b b G G G G A B a b G a b G P X Y T D_1FP UK.indd RH
