Product Description

HYDAC DR08P series pilot-operated spool type pressure reducing cartridge valves. Their core difference lies only in the pressure adjustment range. They are designed to stabilize branch pressure in hydraulic systems, compatible with UNF-threaded FC08-3 cavities, with a maximum pressure resistance of 350 bar, a flow rate range of 0–60 L/min, NBR sealing material, and excellent corrosion resistance and stability. The product explanation is expanded below from model code interpretation, core features, technical parameters, working principle and application scenarios.

I. Model Code Interpretation (DR08P-01-C-N-XXXV)

Code Segment	Meaning
DR08P	Pilot-operated spool type pressure reducing valve, size 08, P series
01	UNF-threaded mounting interface
C	Cartridge valve core only (valve block or valve sleeve required for assembly)
N	Sealing material: NBR (Nitrile Butadiene Rubber)
090V/330V/500V	Pressure adjustment range identifier: 090V ≈ 6–125 bar, 330V ≈ 100–275 bar, 500V ≈ 200–345 bar (all within the 6–345 bar product family range)
V	Adjustment method: Tool-adjustable (e.g., hexagon socket)

II. Core Features

Pilot control + spool structure: The main valve is controlled by a pilot stage, featuring fast response speed, stable pressure across the full flow range, and adjustable flow from 0 to 60 L/min.
High protection and durability: The external surface is treated with zinc-nickel plating (passing 1,000-hour salt spray test); the orifice is equipped with a filter screen for protection; internal components are hardened and precision-ground, resulting in low wear and long service life.
Compact cartridge design: Compatible with FC08-3 standard cartridge cavities, which helps save installation space and simplifies system integration and maintenance.

III. Typical Application Scenarios

Industrial hydraulic systems: Machine tools, injection molding machines, hydraulic presses, providing stable control pressure for actuators (cylinders, motors)
Mobile hydraulic equipment: Construction machinery, agricultural machinery, ensuring reliable pressure supply for auxiliary circuits
High-precision hydraulic systems: Testing platforms, servo systems, requiring consistent pressure output under variable flow conditions
