Description
Description: This hydraulic valve is mostly used for log splitter devices which cut the log or wood (part of log) into smaller pieces. For this reason this valve is also called log splitter valve. It is directing the fluid from hydraulic pump to hydraulic cylinders and the hydraulic tank. The valve has 3 positions with detent in one position which is released when the pressure reaches certain level. The purpose of this pressure released detent is to automatically kick back the valve into its neutral position when hydraulic cylinder completes the stroke. For this reason this hydraulic valve is also called automatic kick back valve. It is manufactured with adjustable inlet relief valve.
Construction: Valve is made out of a single block (monoblock). Its body is made of cast iron EN-GJL-300. Plunger is made of carbonized steel with hard chrome plating. Lever can be installed looking up or down from the valve main body.
