Hydraulic control valve, Hydraulic control valve, Supplier at Sonu Hose Pipe New Delhi Hydraulic Control Valve – Two Long Levers: Used to manually control the hydraulic flow. Each lever operates one spool inside the valve. Valve Body: Made from heavy-duty cast iron or steel. Painted or coated for corrosion resistance. Ports with Red Protective Caps: These are hydraulic ports (inlet/outlet). Caps prevent dust and dirt from entering when not connected. Spool Sections (Below Levers): Each spool inside moves up/down when the lever is pulled or pushed. They control the direction of hydraulic fluid (e.g., extend/retract a cylinder). Mounting Points: Bolt holes for securing the valve to a machine or platform. Main Parts: Part Description Levers Manual control for each hydraulic circuit. Dust Boots Rubber seals around the levers to protect internals from contamination. Spool Valves Internal moving parts controlling fluid flow based on lever position. Hydraulic Ports Connections for hoses (Pressure Inlet, Tank Return, Work Ports). Valve Body Main structure holding all components. How It Works: Input Pressure: Hydraulic fluid under pressure enters the valve via the inlet port. Lever Movement: Moving a lever shifts a spool inside the valve. Flow Control: Depending on the spool position, the fluid is directed to either one work port or another, moving an actuator (like a hydraulic cylinder or motor). Return Flow: Fluid returns to the tank when not directed to an actuator. Typical Applications: Agricultural machinery (tractors, harvesters) Construction equipment (loaders, excavators) Industrial hydraulic systems Forestry and material handling machines Common Features: Load-holding capability (prevents cylinder movement when lever is released). Detent positions (locks lever in place if needed). Pressure relief valves (protection against overpressure). Parallel or series circuits depending on configuration.
