[ Screw-in Cartridge Valves]
Screw-in cartridge valve is one branch of hydraulic valves, it use screw thread as connecting way, that reduce many tube connections and make the valve more compact size, speedy acting, convenient fixing and unfixing, steady function. Due to these characters, Cartridge Valves have been widely used in construction machine, hydraulic system and many other hydraulic industry fields.
Hydraulic cartridge valve can be directly screwed into cavity of manifold block or single body (metal block), therefore failure caused by leakage, shaking, noise or tubing can be much reduced and dependability can be significantly improved.
A wide variety of cartridges allows engineers to find almost any hydraulic control function in cartridge form - with very few limitations.

Features:
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.
