Description:
The R40 ECO manual hydraulic valve is designed to distribute and control hydraulic oil flow between the hydraulic pump and hydraulic consumers (cylinders, hydraulic motors, etc.).
The hydraulic valve is used for various applications in agriculture, forestry, construction and industry to control:
-
single-acting cylinders
-
double-acting cylinders
-
hydraulic motors
-
float function (depending on the version)
-
other hydraulic consumers
R40 ECO valves are available in a monoblock design with 1 to 7 sections. The ECO version offers a more affordable alternative to standard valves while maintaining comparable manufacturing quality, reliable operation and a long service life.
Operation:
All hydraulic valves are equipped with an adjustable pressure relief valve. In the neutral position (lever in the center), oil flows through the valve. Moving the lever in either direction directs the oil flow to the connected hydraulic consumer, allowing control of hydraulic cylinders or hydraulic motors. When released, the lever automatically returns to the neutral position, ensuring safe and reliable operation.
Versions with a float function allow free oil flow, enabling the cylinder to move freely or the attachment to follow the terrain.
Construction:
The R40 ECO is a monoblock hydraulic valve made from a high-quality cast housing. The internal components are precisely machined to ensure a long service life, reliable operation and wear resistance, even under demanding operating conditions.
Connections:
The valve is equipped with standard hydraulic ports for quick and easy connection to a hydraulic system. It is suitable for use on tractors, machinery, attachments and other hydraulic equipment.
