– Raw Materials Selection Of Manifold Hydraulic Blocks As Per Different Pressure –

Max. Operation Pressure: P<6.3MPa (914psi) : Costing Iron HT20-40
Characteristics: For large quantity manufacturing, reducing manufacture hours and increasing efficiency, especially for standardized pattern valve blocks.
Max. Operation Pressure: P<21MPa (3045psi) : Aluminum alloy 6061-T6
Characteristics: Our standard material for manifold blocks, with medium strength, good corrosion resistance, weldability, good oxidation effect. With good flatness. Improve processing efficiency and reduce material costs. This will be the best choice for low price, high quality materials for hydraulics.

Max. Operation Pressure: P<30MPa (4350psi) : Aluminum alloy 7075-T6
Characteristics: The best strength of aluminum alloy is 7075 alloy, its strength can be similar to medium carbon steel, but it can’t be welded, and its corrosion resistance is good enough and price is higher than 6061.

Max. Operation Pressure: P<35MPa (5075psi) : Carbon steel 45#
Characteristics: With high strength and good machinability, after appropriate heat treatment can obtain a certain toughness, plasticity and wear resistance, the source of the material is convenient, with good overall mechanical properties.

– Need To Know Before Design Of Manifold Blocks –

  • Thickness Valve Block
    The initial thickness of the valve block is set to be 5 times of the maximum diameter of the valve port, then gradually reduced according to the specific requirement.
  • Drilling Oil Holes
    The deep, inclined and process holes must be as less as possible, the large flow chamber should be taken into account first, and then is the pilot chamber.
  • Wall Thickness Of Each Port
    Safety wall thickness between the oil chamber shall not be less than 3~5mm, and the deflection of the drill within the allowable range shall be considered.
  • Oil Chambers 
    The flow rate of hydraulic oil in the chamber should not be higher than 12m/s, and the oil return chamber should be 20-40% larger than the inlet chamber.

Customer Reviews

“The product had a nice looking, and worked fine. Looks like it is to be well made and seems to hold up. I’m going to order another one.”


Lauren Mark

“The price paid is well to me. The working pressure of 3000 PSI (max) is fine until now. It looks great and hopefully it will live up to the “QUALITY” claims that it made.”

Tyron Olson

“We used valve blocks as replacement in our new projects. We checked and these were working OK and the price was good. They fit perfectly and are operating great.”

Aaron Roca

“We paid a lot more for overpriced original parts before. These factory items work just fine…better actually. These fit perfectly and have no problems at all.”
