What are Monoblock Valves and where to use them?

Monoblock directional control valves have many outstanding features and can be used in many applications, in our latest blog we uncover what exactly the valves are and where they can be used.



What are Monoblock valves?

The valves have many outstanding features including high performance, high efficiency, small volume, mass flow and are leak proof.


In addition, the compact directional control valves have fixed and big pull rod to control direction, providing various ports and circuit valves.  The valve offers various operation methods including manual control, pneumatic control, hydraulic and electro-hydraulic control and can select these methods according to customers’ requirement.



  • 2 Spool valve with compact design allows for installations in tight areas
  • All spools are standard double acting with spring return to neutral position which are ideal for double acting cylinders
  • Used for open center systems (Pump to Tank Flow) – closed center option available
  • Anti-drop load checks on each spool
  • Precision ground and hard chrome-plated spools assure a long life
  • High-tensile strength cast iron monoblock construction
  • SAE O-Ring ports ensure solid seal and prevent blockages
  • Capable of closed centeror Power Beyond (conversion plug required)
  • Vertical or horizontal handle mount
  • Adjustable Relief Valve Range:  1500 to 3625 PSI
  • Preset Pressure Relief: 2610 PSI
  • Used as motor or single-acting spool possible (#8 SAE port plug required)




Where are they used?

These valves are used to start and stop fluid flow into hydraulic cylinders or hydraulic motors and are used in the agricultural, industrial and mobile industries to provide smooth operation, low-pressure drop, and rapid response for precise fluid control in a lightweight constructed valve.

Their applicability makes them increasingly sought after and are used in many applications, such as:

  • Car carriers
  • Machinery – Tractors
  • Assembly lines
  • Energy production
  • Marine equipment
  • Construction machines
  • Mining machines
  • Material handling cranes
  • Trucks & Rigs



Common Uses: 

  • Operate hydraulic cylinders (Double-Acting or Single-Acting)
  • Operate hydraulic motors (“D” Spool Required)
  • Install rear remotes on a tractor


There are five main operating methods used for directional control valves, all dependent on their applications: manual, spring, electrical, pneumatic, and hydraulic.
