Description
Description: Manually or mechanically controlled hydraulic directional control valve is designed for distribution and control of working fluid between generator (pump) and executive mechanisms (cylinder, hydro-motor, etc.). It is manufactured with 2 plungers, with parallel connection, with common check valve for each plunger and with safety valve. Position number 3 on section 2 (check below) is used to allow attached cylinder to float freely. Hydraulic fluid can float freely between each sides of cylinder piston (from port A to port B) thus allowing it to be adjusted to outside forces. This kind of feature is called floating feature. Mostly this feature is used for snow pushers or snow plowers.
Construction: Valve is made out on single block (monoblock). Its body is made of cast iron EN-GJL-300. Plungers are made of carbonized steel with hard chrome plating.
