503021 JS-L22 MDCV

Purpose and characteristics 

The JS-L22 MDCV, a patented product developed by our company, features beautiful appearance, delicate structure, high pressure, large flow and strong pollution resistance and is an upgrade product of the MDCVs of ZS and ZFS series. If overload valve and oil supplement valve are not needed in oil line, it can fully replace the MDCV of ZL(DL) series and has remarkable advantage in cost performance.

The JS-L22 MDCV is widely applied to the hydraulic systems of various kinds of engineering machinery, agricultural machinery, road-bridge machinery, environmental sanitation machinery, mining machinery and the like in which assistant control valve is not needed in valve group.

Performance characteristics 

Through neutral-position runner unloading and overload valve configuration, the pollution resistance and reliability are enhanced. Design of zero external leakage is adopted at the two ends of reversing slide valve. The leakage amount is small at the reversing position, and control under high- and low-pressure is easy. Any combination of sections1-10 may be applied. The slide valve functions of types 0, Y, A and N are available for choice. Multiple control modes may be adopted, such as spring return, steel ball positioning, pilot-operated reversing and pneumatically-operated reversing; and return valve plate may be a bridge valve.
