Argo-Hytos CETOP 3 Hydraulically Operated Directional Control Valves
When you need precise, reliable directional control in a compact CETOP 3 package, the Argo-Hytos RPH Series delivers. The RPH2-06 and RPH3-06 are 4/2 and 4/3 direct-acting directional control valves designed for demanding mobile and industrial hydraulic applications — handling up to 80 l/min at pressures up to 350 bar.
Both valves mount to a standard CETOP 3 (D03) subplate interface to ISO 4401 / DIN 24340, making them straightforward drop-in solutions for new builds or replacements. A five-chamber housing design minimises pressure drop and reduces sensitivity to fluid viscosity, keeping performance consistent across varying operating conditions. A wide range of interchangeable spool configurations is available to match your circuit requirements.
- RPH2-06 — hydraulic pilot operation (min. pilot pressure 30 bar). The actuating section rotates in 90° increments for installation flexibility, with pilot connection options including M10×1, G1/8, and 7/16-20 UNF-2B (SAE-4).
- RPH3-06 — hydraulic or pneumatic pilot operation, with a low minimum pilot pressure of just 2 bar for maximum hydraulic power. Pilot connections: M10×1, G1/8, or G1/4.
Both models are available with enhanced corrosion protection rated to 520 hours salt spray (ISO 9227) — suitable for mobile machinery operating in harsh NZ environments.
