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 4 plungers, with parallel connection, with common check valve and with safety valve.
Construction: Valve is made out of a single block (monoblock). Its body is made of cast iron EN-GJL-300. Plungers are made of carbonized steel with hard chrome plating.
