What are subplates and hydraulic manifold blocks?
In traditional systems, each directional control valve requires multiple hoses to be screwed directly into its body. The CETOP system works completely differently. A subplate (or multi-station manifold block) is a solid component made of steel or aluminum, with all supply (P) and return (T) channels milled inside.
You connect the power supply from the pump and the hoses going to the actuators (A and B ports) to the subplate. You place the directional control valves and modular valves on the perfectly flat top surface of the block, fastening them with only four screws. Oil flows between the sections through internal channels, completely eliminating the need for external piping between sections!
Why invest in hydraulic manifold blocks?
- No more leaks: Replacing a dozen external hoses, fittings, and tees with a single solid steel block drastically reduces the risk of system leakage under pressure and vibration.
- Instant service (Zero downtime): If a directional control valve fails, you simply unscrew it from the top and replace it with a new one. You don't unscrew a single hydraulic hose! The base and piping remain untouched.
- Lego-like architecture: Manifold blocks allow for the creation of "sandwich" hydraulic towers. Between the block and the directional control valve, you can insert sandwich valves (hydraulic locks, restrictors, pressure regulators), creating advanced control systems in minimal space.
- Standardization: Subplates are manufactured to a universal standard (ISO 4401). This means that directional control valves from every leading manufacturer worldwide are compatible with them.
What solutions will you find in our offer?
In the BRhydraulic assortment, we have prepared solutions tailored to every project:
- Single subplates (single station): Ideal for controlling a single actuator or hydraulic motor. Available in versions with side or bottom (rear) connections, which facilitates installation in confined spaces.
- Multi-station manifold blocks: Designed for complex machines. They allow for the installation of 2 to even 8 or more directional control valves on one common block. They have a common supply (P) and return (T) channel for all sections.
- Manifold blocks with integrated relief valve (DBV): An integrated safety valve directly in the block protects the pump and the entire system from bursting in case of a sudden pressure surge.
Choose the right size
We offer subplates and blocks in the most popular industrial sizes:
- NG6 (CETOP 03): For flows up to approx. 60-80 l/min. (Connections most often 3/8" or 1/2").
- NG10 (CETOP 05): For heavy duty and flows of 120-160 l/min. (Connections most often 1/2" or 3/4").
