Let’s delve deeper into the world of hydraulic valves. They are the control center of a hydraulic system, determining the direction, pressure, and flow of hydraulic fluid.

Types of Hydraulic Valves:

• Directional Control Valves:
  • Determine the direction of fluid flow.
  • Types include spool valves, poppet valves, and cartridge valves.
  • Examples: 2/2, 3/2, 4/3 way valves.
• Pressure Control Valves:
  • Regulate system pressure.
  • Types include relief valves, sequence valves, pressure reducing valves, and pressure compensated flow control valves.
• Flow Control Valves:
  • Control the flow rate of hydraulic fluid.
  • Types include fixed displacement, variable displacement, and pressure compensated flow control valves.

How Valves Work:

Valves operate by using hydraulic pressure to shift spools or pistons, which in turn control the flow of fluid through various ports. The design of the valve determines its function and the specific control it provides.

Strainers and filters are both components used to protect hydraulic systems from contaminants, but they serve different purposes based on the size of particles they remove.  

1. Are Suction Filters Still Necessary in Hydraulic Systems? | DOMS Inc.

Strainer

• Removes larger particles: Typically removes particles greater than 40 microns.   1. Differences Between a Filter and a Strainer in a Hydraulic System – Fluid Power Journal fluidpowerjournal.com
• Coarse filtration: Acts as a first line of defense against large contaminants.   1. Difference Between a Filter and a Strainer | Dombor www.dombor.com
• Easy cleaning: Can be cleaned and reused.   1. Cleaning the Strainers – Horne Engineering www.horne.co.uk

Filter

• Removes smaller particles: Typically removes particles smaller than 40 microns.   1. Differences Between a Filter and a Strainer in a Hydraulic System – Fluid Power Journal fluidpowerjournal.com
• Fine filtration: Provides a higher level of cleanliness.
• Less frequent cleaning: May require replacement rather than cleaning.

In essence, strainers are a coarse filter that protects the system from larger debris, while filters provide finer protection by removing smaller contaminants.
