[Directional Control Cartridge Valves]
Directional control cartridge valves can be divided into Check Valves,Shuttle Valves,Hydraulic/Mobile/Manua directional Valves
[Cartridge Check Valves]
A Check Valve allows fluid flow only in one direction, and does not allow the reverse flow. It can be used on the export of hydraulic pumps, in order to prevent fluid backflow; separated the link between the Circuit, in order to interfere with each other; parallel to the sequence valve, pressure reducing valve, throttle and Speed Control Valve parallel to form a Check Sequence Valve, check pressure reducing valve, check throttle speed control valve and so on.
To choose the Check Valve should according to different application place, conform the opening pressure. If be used as back-pressure valve, generally the opening pressure should be higher; if just use as control the fluid to one way flow, can choose the lower opening pressure check valve.
[Cartridge Shuttle Valves]
In certain fluid power systems, the supply of fluid to a subsystem must be from more than one source to meet system requirements. In some systems an emergency system is provided as a source of pressure in the event of normal system failure. The emergency system will usually actuate only essential components. The main purpose of the shuttle valve is to isolate the normal system from an alternate or emergency system. It is small and simple; yet, it is a very important component

[Features of cartridge valves]
1.Light weight and compact size
-Combining several functions into a single manifold may save valuable space and weight, often occupying only 10% to 20% as much volume as conventional line-mounted systems plumbed with fittings, hose, and tubing.
2.Leakage prevention
-Because a valve package eliminates so many connections, system leakage potential is reduced drastically.
3.Efficiency for the system
-Valve packages that eliminate interconnecting lines and fittings lead to higher overall system efficiencies
4. Convenience and Serviceability
-Being more compact, valve packages sometimes can be mounted where they are less susceptible to external damage.
-Cartridges usually can be removed and replaced quickly without disturbing any external plumbing.
5. Aesthetics and Economy
-A clean design will not affect performance, but a good-looking machine on the dealer's sales floor in a competitive market can be an advantage to the OEM.
-On many systems, the cost of a custom valve package ,can be equal to (or less than) that of a system with individually plumbed components.
