An electro-hydraulic flow control valve electronic, also known as an electro- proportional control valve or simply an EPV, is a type of valve that uses electrical signals to control fluid flow rate or pressure. It operates based on the principle of proportional control, where the valve's position is adjusted proportionally to the input signal received. What Is electronically controlled hydraulic proportional valves? An proportional relief valve hydraulic, also known as an electro proportional valve, is a type of valve that utilizes an electrical signal to control and regulate the flow rate or pressure of a fluid within a hydraulic or pneumatic system. It operates based on the principle of proportionality, where the valve's position or opening is directly proportional to the electrical input signal received. Electro proportional hydraulic solenoid valve are designed to provide precise and accurate control over fluid flow or pressure, allowing for fine-tuning and dynamic adjustment in various applications. They are commonly used in industrial automation, robotics, machine tools, material handling equipment, and other systems where precise control and responsiveness are required. The electrical signal can be generated by a control system or a proportional control device, enabling proportional control of the valve's position or flow rate based on the desired setpoint or feedback signals. How Does Proportional Valve Work? Proportional valves work by utilizing an electrical signal to control the position or opening of the valve, which in turn regulates the flow rate or pressure of a fluid within a hydraulic or pneumatic system. Proportional valves provide accurate and dynamic control over fluid flow or pressure, allowing for precise regulation and responsiveness in a wide range of applications. The electrical signal input determines the valve's position or opening, resulting in proportional control of the fluid flow or pressure in real-time. Electrical Input An electrical signal is sent to the proportional valve, typically from a control system or a proportional control device. This signal represents the desired flow rate or pressure setpoint. 01 Valve Response The electrical signal is received by the valve's internal electronics, which convert it into a corresponding mechanical output. This output is used to position or adjust the valve's opening. 02 Spool or Piston Movement The mechanical output from the valve's electronics actuates a spool or piston mechanism within the valve. This movement adjusts the size of the flow passage or changes the valve's internal geometry, affecting the fluid flow rate or pressure. 03 Fluid Flow Control As the spool or piston position changes, the fluid flow rate or pressure through the valve is modulated accordingly. The proportional relationship between the electrical input signal and the valve's position allows for precise and proportional control of the fluid flow rate or pressure.

An electro-proportional directional valve is a type of hydraulic valve that is used to control the direction of fluid flow in a hydraulic system with high accuracy and precision. It plays a vital role in ensuring optimal performance and efficiency in various applications. How Is An Electro-proportional spool valve Controlled? An electro-proportional directional control valve is controlled using electrical signals to determine the direction and flow of fluid in a hydraulic or pneumatic system. The valve contains a proportional solenoid that responds to the electrical input signal and adjusts the valve's internal components to control the fluid flow path. Electrical Input Signal The valve receives an electrical input signal, typically a current or voltage signal, from a control system or device. This signal is proportional to the desired position or operation of the valve. 01 Proportional Solenoid The valve contains a proportional solenoid that converts the electrical input signal into a magnetic field. The strength of the magnetic field is proportional to the magnitude of the input signal. 02 Spool Positioning The magnetic field generated by the proportional solenoid interacts with the valve's internal spool, which is typically spring-loaded. The solenoid's magnetic force counteracts the spring force to position the spool. 03 Spool Movement As the solenoid's magnetic force increases or decreases in response to the electrical input signal, it moves the spool within the valve body. The spool's position determines the flow paths and connections within the valve. 04 Fluid Flow Control The movement of the spool opens or closes specific flow paths or ports within the valve. This controls the direction and magnitude of fluid flow in the hydraulic or pneumatic system. 05 Feedback Some electro-proportional directional control valves may have built-in position sensors or provide feedback signals to the control system. This feedback enables the control system to monitor and adjust the valve's position for precise control and closed-loop operation.

Direct-acting sequence valves are widely used in applications where precise sequencing of hydraulic actuators is required. They are commonly found in machinery, manufacturing equipment, and systems that involve complex movements and coordinated operations. How A Direct-Acting Sequence Valve Typically Works Valve Structure A direct-acting sequence valve consists of a valve body, a valve spool or poppet, and various ports for hydraulic fluid flow. The valve is typically spring-loaded. 01 Inlet and Outlet Ports The valve has an inlet port that receives pressurized hydraulic fluid from a pump or another power source. It also has one or more outlet ports that are connected to the hydraulic actuators or cylinders. 02 Set Pressure The valve is designed to open and allow fluid flow to the outlet ports once the pressure at the inlet port exceeds a specific pre-set pressure level. This pressure level is often adjustable and determines the sequencing order. 03 Pressure Differential When the pressure at the inlet port surpasses the set pressure, it acts on the valve spool or poppet, overcoming the spring force and initiating valve movement. 04 Flow Diversion As the valve opens, hydraulic fluid is allowed to flow to the outlet ports. This enables the actuator or cylinder connected to the first outlet port to begin its intended operation. 05 Sequential Operation Once the actuator connected to the first outlet port completes its stroke or reaches its end position, the pressure at the outlet port decreases. 06 Valve Reset As the pressure drops at the first outlet port, the spring force becomes stronger than the pressure force, causing the valve to close and redirect the hydraulic fluid flow to the subsequent outlet port. 07 Subsequent Actuators The hydraulic fluid flow is then directed to the next outlet port, activating the second actuator in the predetermined sequence. This process continues until all the desired actuators have completed their strokes. As a cartridge valve manufacturer, we provide screw in hydraulic cartridge valves, sequence valve in hydraulic system, pilot operated sequence valve, etc. For more about hydraulic sequence valve operation and sequence valve working, contact us.
