the hydraulic control valve

Hydraulic control valve

Edit this paragraph
(Referred hydraulic valve) is a hydraulic system control element for controlling the hydraulic system pressure of the fluid flow and flow direction, so as to meet the various requirements of different actions actuator.

Hydraulic control valves can be divided according to their role in directional control valves, pressure control valves and flow control valves three categories, corresponding by these valves are three basic circuit: direction control loop pressure control loop and speed loop. Press the control of different ways, can be divided into ordinary manifold block  valve hydraulic control valve, servo control valves, proportional control valve. Different forms depending on the installation, hydraulic valves can be divided into tubular, plate and cartridge type, and so are several.
Composition

Edit this paragraph
 Two-way cartridge valve from the cartridge device, the control cover, pilot control valves, manifold blocks, four-part

1 Cartridge - also known as the felling assembly, which consists of spool and sleeve, springs and seals four kinds of parts. Main function is used to control the direction of the main oil line, pressure and flow.

2 Control cover - from the cover of the embedded micro-pilot control element (throttling plug) as well as other parts and other accessories. It is mainly used to secure and guarantee Cartridge seal; communication control oil and felling the link between the control chamber and implement control.

3 pilot control valve - mounted on the control cover (also can be installed directly on the manifold body), is the implementation of action for felling Cartridge smaller gauge reusable fitting control valve. Mainly pain ¢ 10 ¢ 6 and the standard diameter solenoid valve, proportional valve, adjustable dampers, buffers, etc.. Felling larger size may need to use a smaller two-way cartridge valves for secondary control. Dimensions comply with ISO and national standards solenoid valve can be interchanged with the installation of similar products at home and abroad.

4 manifold blocks - used to install Cartridge, covers and other control valve control, communication and control circuit of the main oil blocks
