Hydraulic control valves for open center systems – flow up to 40 l/min

Hydraulic control valves with a flow rate of up to 40 l/min dedicated to open center systems (Open Center) are among the most popular and versatile control units in power hydraulics. The open system is characterized by the fact that in the neutral lever position, oil flows freely from the pump to the tank, without loading the system. A throughput of 40 liters per minute represents an ideal compromise between the compact dimensions of the device and high operating efficiency.

Application of 40 l/min control valves

Due to optimal flow parameters, control valves from this group find very wide application in low and medium power agricultural, construction, and industrial machinery. They are commonly used in:

• agricultural tractors, front-end loaders, and forage machinery,
• small and medium excavators, loaders, and mini-excavators,
• log splitters, sweepers, and snow plows,
• forklifts, cherry pickers, and truck-mounted cranes (HDS),
• stationary hydraulic power units and small presses.

Advantages and structural characteristics

1. Free oil circulation: the Open Center design ensures that when there is no load, the pumps do not generate unnecessary resistance, which prevents oil overheating and reduces fuel consumption.
2. Compact dimensions and high durability: strong, cast-iron body construction guarantees resistance to high operating pressures and mechanical overloads in difficult working conditions.
3. Expandability: these control valves are often equipped with adjustable relief valves (safety valves) and the option to connect a power beyond sleeve for series connection with subsequent control valves.
4. Control versatility: depending on needs, a given unit can be controlled manually by levers, electrically, pneumatically, or using cables and a joystick.
