Control valves are the components of hydraulic system, the main assignment of which is to control the flow in the hydraulic lines.
Spool valves. In the spool type valves the flow direction is fulfilled by means of axial shift of spool control element. Hydrosila manufactures two types of control valves: monoblock and modular control valves.
Monoblock control valves have classic effective design. All the spools are installed in one body and it gives the opportunity to refine the size and the weight of the control valve for the separate kind of machine.
Modular control valves have several cells, what gives the opportunity to use the valve for control of hydraulic system with different actuators. The main advantage of the modular control valve – when using the valve only the separate section may be changed if it’s out of order.
