Control Methods and Price Factors for Directional Spool Valves

How much do you know about the control methods of directional spool valves?


As we all know, whether it is a directional spool valve or other valves, there are control methods. Different application scenarios can choose different control methods. So how much do you know about the control methods of directional spool valves?


  • Manual control: A control method operated manually (by hand or foot), abbreviated as manual or foot-operated.

  • Mechanical control: A control method operated by mechanical parts such as shafts, cams, and levers, abbreviated as mechanical directional spool valve.

  • Hydraulic control: The directional spool valve is controlled by the pressure of the liquid in the pressure control pipeline, abbreviated as hydraulic or hydraulic control.

  • Pneumatic control: The directional spool valve is controlled by the pressure of the air in the pressure control pipeline, abbreviated as pneumatic control.

  • Electrical control: The directional spool valve is controlled by the electrical state changes, abbreviated as electric controlled directional spool valve.

  • Servo control: A control method that compares the given signal on the controlled component with the actual state signal and performs control according to the signal error.

  • Automatic control: A control method for directional spool valves that does not require human intervention.

  • Internal pressure control: A control method that provides control fluid from within the controlled component, abbreviated as internal control.

  • External pressure control: A control method that provides control fluid from outside the controlled component, abbreviated as external control directional spool valve.

  • Internal oil drainage: A method of combining oil drainage with oil return inside the component, abbreviated as internal drainage or internal discharge.

  • External oil drainage: A method of separately discharging oil from the oil drain of the component, abbreviated as external drainage or external discharge.


What are the factors that affect the price of directional spool valves?


When it comes to the price range of directional spool valves, it is generally quite stable. The price of directional spool valves is often a key factor in purchasing decisions. So what factors affect the price of directional spool valves?


  • The materials used to make directional spool valves. If high-tech products are used, among all raw materials, choosing top-level configurations will definitely be more expensive.

  • The use of production technology will also affect the price of directional spool valves. If it is a more refined and advanced processing technology, the price of such products will be relatively high.

  • The composition of the equipment. For some larger equipment or products with more complex components and more components, the price will be higher.
