hydraulic valve , Iran
A proportional hydraulic valve is an advanced control valve that regulates hydraulic oil flow and pressure linearly and precisely. The body is made of hardened steel or durable aluminum, capable of handling working pressures from 250 to 350 bar. Flow rate depends on valve size and electromagnetic control, ranging from 5 to 150 liters per minute. These valves are typically operated by an electromagnetic coil and provide fast response to electrical signals with ±2 percent accuracy. Internal design includes chromium-plated cores, precision springs, and O-rings resistant to high temperature and pressure.
Structurally, the proportional valve includes standard inlet and outlet ports, cartridge or flanged connections, and vibration-resistant fittings. Electronic or digital control systems enable smooth adjustment of flow and pressure, reducing shocks and fluctuations in hydraulic circuits. These valves are used in machine manufacturing, automated equipment, hydraulic presses, and mobile hydraulic systems requiring high precision. High wear and corrosion resistance ensures service life exceeding 500,000 operating cycles.You can order and buy hydraulic valve from Iran by contacting us through whatsaap and email.

Function Diagram and Flow of a Proportional Valve in iran
A hydraulic proportional valve controls oil flow proportionally to an electrical input signal. In no-load condition, the valve is closed and no flow occurs. Increasing the input signal 0–10V or 4–20mA opens internal paths, increasing oil flow to the output port. The valve consists of a movable spool and an electromagnetic coil. Spool movement changes the cross-sectional area of flow paths. Return flow to the tank is controlled via the T port to maintain system pressure. The flow diagram usually shows P pressure, A and B output, and T return ports with flow direction and spool position.
