Flow regulating valve
Flow-regulating valves control actuator speed by adjusting the fluid flow in hydraulic or pneumatic systems. They balance flow between multiple branches so actuators operate at coordinated speeds.These valves protect systems from excessive flow that can cause over-speeding or damage.Pressure-compensated types keep flow constant even when system pressure changes.They improve safety and efficiency by enabling meter-in/meter-out control and regulating cooling or lubrication flow.
A flow-regulating valve controls the rate of fluid passing through a restricted opening (orifice).When the valve is adjusted, the size of the orifice changes, increasing or decreasing flow.A smaller opening creates higher resistance, reducing flow rate.A larger opening lowers resistance, allowing more fluid to pass.Flow rate directly affects the speed of actuators like cylinders and motors.In pressure-compensated types, a compensator spool adjusts automatically to maintain constant flow.This compensator reacts to pressure changes and keeps the orifice size stable.As load pressure increases, the valve reduces the opening to keep flow constant.As load pressure decreases, the valve increases the opening to prevent overspeed.Overall, the valve ensures smooth, controlled, and predictable movement in fluid-powered systems.
