Argo-Hytos Manifolds and Connecting Plates

Argo-Hytos hydraulic manifolds connect individual sections of a hydraulic circuit and carry out specific control functions through the valves mounted on them.

The range runs from standardised connecting plates, which join ISO 4401 (CETOP) modular valves and screw-in cartridge valves into compact circuits with little or no pipework between valves, to manifold blocks designed for individual applications.

Standard products include serial plates, subplates, blanking and adaptor plates, sandwich plates and in-line bodies for cartridge valves, and power pack base manifolds with a pressure relief valve.

Manifolds and plates are made in aluminium alloy, grey cast iron or steel. Standard plates suit valve sizes 04 (D02), 06 (D03) and 10 (D05), with maximum operating pressures from 250 bar for aluminium serial plates up to 420 bar for steel cartridge valve bodies and sandwich plates. The products below are a selection of the main ranges; further plates and configurations are available, and our team can help with any Argo-Hytos manifold you need.

Argo-Hytos Manifold and Plate Range

Hydraulic Manifold Blocks

  • Application-Specific Manifolds: Argo-Hytos designs manifold blocks for individual applications, ranging from economical designs to more technically advanced solutions, in aluminium alloy, grey cast iron or steel. A manifold block brings the valves for a circuit or machine function together in one housing, reducing pipework and leak points. Examples in the Argo-Hytos portfolio include central control blocks for tractors and main control blocks for multifunctional tool carriers. Contact our team with your circuit or existing block details for advice on a suitable manifold.

Sub-Plates for Valves with a Body and Modular Valves

  • PD04, PD06 and PD10 Serial Plates with Side Ports: Connect two or more ISO 4401-02, 03 or 05 valves in parallel, with A and B consumer ports on the side of each section. Up to 8 sections on PD04 and 6 on PD06 and PD10, in aluminium rated to 250 bar. Stackable versions mount on the SMA05 power unit block (PD04, PD06) or ZB06 and ZB10 base plates (PD06, PD10). Maximum flow can be up to doubled by feeding the plate from both ends.
  • DR1-04 and DR2-06 Serial Plates: Compact serial plates for ISO 4401-02 and 03 valves with integrated cavities for a pressure relief or unloading valve (3/4-16 UNF on DR1-04, 7/8-14 UNF on DR2-06). Up to 8 sections on DR1-04 and 10 on DR2-06. DR1-04 is aluminium rated to 320 bar; DR2-06 is aluminium (320 bar) or steel (350 bar).
  • DP Subplates: For mounting a single ISO 4401 valve in a circuit connected by tubes or hoses. Size 04 is rated to 320 bar and sizes 06 and 10 to 350 bar, with metric, BSP, NPT and SAE port threads depending on model. Phosphated as standard, with zinc-nickel coating as an option.
  • DK1 Blanking Plates and DA Adaptor Plates: DK1-04, 06 and 10 blanking plates close off unused valve positions on serial plates. DA-06/04 and DA-10/06 steel adaptor plates, rated to 350 bar, allow a size 04 valve to be mounted on a size 06 interface or a size 06 valve on a size 10 interface.

Bodies for Screw-in Cartridge Valves

  • SB In-Line Bodies: Single, dual and triple bodies that let screw-in cartridge valves be fitted directly into pipework. Cavities cover 2, 3 and 4-way valves in UNF and UN threads from 3/4-16 to 1-5/16-12, metric threads from M20x1.5 to M38x2, and slip-in valves, with BSP and SAE connecting ports from G1/4 to G1. Aluminium bodies are rated to 250 bar, cast iron to 350 bar (with a gauge port) and steel to 420 bar.
  • SB-04, SB-06 and SB-10 Sandwich Plates: Sit between an ISO 4401 size 04, 06 or 10 valve and its serial plate or subplate to add 2 or 3-way cartridge valves to the stack, in single, dual or piloted configurations. Cast iron (350 bar) or steel (420 bar), stackable on PD and DR serial plates.

Power Pack Base Manifolds with Built-in Pressure Relief Valve

  • DP6 Base Manifold: For systems or power units needing a single CETOP 03 or CETOP 05 directional valve. Steel, rated to 350 bar, with an integrated direct-operated pressure relief valve and maximum flows of 50 l/min (size 06) and 120 l/min (size 10). Relief settings are available in ranges up to 320 bar.
  • ZB06 and ZB10 Base Plates: Tank-cover mounted base manifolds for power packs with one directional valve, stackable with PD06 and PD10 serial plates to add further valves. Integrated functions include circuit unloading drain, main circuit check and a pressure relief valve cavity; the relief valve is supplied separately. Steel versions are rated to 320 bar and aluminium to 250 bar, with maximum flows of 50 l/min (ZB06) and 50 or 120 l/min (ZB10, depending on relief valve cavity).
