Rotary Direction Control Valves
The Lever Operated Rotary Direction Control Valves are used in applications which have high pressure and low flow. These are used where leak free operation is required
Hydraulic rotary direction control valves, also known as rotary spool valves or rotary valves, are a type of directional control valve used in hydraulic systems. Unlike linear or lever-operated valves, rotary valves use a rotary motion to control the flow direction of hydraulic fluid. Here are some key features and functions of hydraulic rotary direction control valves
Lever Operated Direction Control Valves
Hydraulic lever-operated directional control valves are a type of manual control valve commonly used in hydraulic systems. These valves are operated by a lever or handle, allowing the user to manually control the direction of hydraulic fluid flow. Here are some key features and functions of lever-operated directional control valves
Manual Operation
These valves are operated manually by a lever or handle. The operator can move the lever to different positions, corresponding to various directions of fluid flow
2-Position Valves
Lever-operated directional control valves are often designed as 2-position valves. The lever typically has two main positions: one for the normal or neutral position, and the other for actuating the valve to control the direction of fluid flow
Spring-Centered or Detent Mechanism
The lever may have a spring-centered mechanism or detent positions that provide tactile feedback to the operator. In a spring-centered valve, the lever returns to the neutral position when released, while a detent mechanism keeps the lever in a selected position until manually moved
Directional Control
The primary function of these valves is to control the direction of fluid flow in a hydraulic system. By moving the lever, the operator can redirect hydraulic fluid to different actuators or components
Single or Multiple Spools
Lever-operated valves can have single or multiple spools. Each spool corresponds to a specific hydraulic circuit, and the operator can choose which circuit to activate by positioning the lever accordingly
Hydraulic Symbols
These valves are represented by specific symbols in hydraulic schematics. The symbols indicate the number of positions, the neutral position, and the flow paths for each position
Application in Mobile Equipment
Lever-operated directional control valves are commonly used in mobile hydraulic equipment, such as construction machinery, agricultural tractors, and forestry equipment. The manual control provides simplicity and reliability in these applications
Compatibility with Different Actuators
These valves can be used with various hydraulic actuators, including cylinders and hydraulic motors, allowing for control over the movement of different components in the hydraulic system
Cost-Effective Manual Control
Lever-operated valves are cost-effective compared to more sophisticated automated or proportional control valves. They are suitable for applications where manual control is sufficient and where automation is not a requirement
Emergency Stop Functionality
In some designs, lever-operated directional control valves may include an emergency stop feature. This allows the operator to quickly stop the hydraulic system in case of an emergency by moving the lever to a designated position
Overall, lever-operated directional control valves provide a simple and reliable means of manually controlling hydraulic systems, making them well-suited for a range of applications, especially in mobile equipment.
