MROStop is an authorized Parker distributor MROStop has been an official distributor of Parker hose and fittings online since 2012. Parker remains one of our strongest supplier relationships to this day. MROStop carries over 40,000 items across Parker's fittings, hose, hydraulic valve, filtration, and pneumatic product lines. This allows us to get customers to best possible pricing and factory lead times available. We not only sell these items but we also have deeply knowledgeable product staff backed up by 76 years of hands on Parker product experience. We are a full service Parker supplier and can provide detailed product support for our customers.
Parker's proportional valves use advanced valve technology and are ideal for applications that require precision and efficiency. They come in a range of performance levels, from standard to highly dynamic. These valves are perfect for industrial and mobile hydraulic applications, providing precise directional and flow control. Additionally, our process control valves can handle a variety of applications, including the control of steam, gas, liquids, and chemicals. Our customers can rely on our valves to operate reliably, even in harsh conditions. ELECTRO HYD PROP VALVE
D91FPZ32HC1NK0L - Pilot Operated Servo Proportional Directional Control Valve - Series D31FP / D41FP / D81FP / D91FP / D111FP
The top-level series of pilot operated servo proportional valves D*1FP is the ultimate choice for highest accuracy in positioning of hydraulic axis and controlling of pressure and velocity. It shows extremely high dynamics combined with high flow. The D*1FP series 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:
D31FP NG10 (CETOP 05)
D41FP NG16 (CETOP 07)
D81FP NG25 (CETOP 08) for port diameter up to 26 mm
D91FP NG25 (CETOP 08) for port diameter up to 32 mm
D111FP NG32 (CETOP 10)
Optionally available with EtherCAT® interface The valves series D*1FP with EtherCAT® interface fulfill the requirements of modern communication between valve and main control. Due to high data transmission speed and short cycle times, the high dynamics can be also utilized within the fieldbus system.
Regenerative/hybrid function (optional) 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. Markets:
Industrial
Machine tools
Molding
Features/Benefits:
Highest dynamics - shorter cycle times and thus higher machine output
High flow capacity - optimum efficiency in relation to valve size
High-resolution position feedback on main spool - assures stable spool position
Progressive main spool design (sinus characteristics) - high-resolution position control at small command signals and for high flows where desirable
Defined spool positioning at power-down - optional P-A/B-T or P-B/A-T or center position (for overlapped spools)
Digital electronics - permits to store and load valve records
Optionally with EtherCAT interface, 2x M12x1, connector 4-Pin (Ether-CAT In and EtherCAT Out) - high dynamics can be also utilized within the fieldbus system
Very robust valve design - lower costs through less downtime
Short delivery time - no warehousing necessary
Additional Features/Benefits Hybrid Version:
Optionally with energy saving A-regeneration or as switchable hybrid version - up to 30 % energy savings through A-return
Minimal expenditure of assembly due to integrated switching between regenerative and standard circuits
Complete functionality in one combined unit
Standard mounting pattern - retrofitting possible
Applications:
General presses
Die cast
Injection molding
Pulp & paper
Technical Specifications: 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 10 % spring offset to spool position A or B (for zerolap spools).
