Level Control Valves

Level control valves are key devices used to automatically maintain the height of liquid in a container or system. They monitor the liquid level in real time through sensors (such as floats, ultrasonic probes), and transmit signals to control units (such as PLC or PID controllers) to drive valve actuators (electric, pneumatic or hydraulic) to adjust the flow to ensure that the liquid level is stable within the set range. This type of valve has both on-off and regulating functions. The core goal is to prevent overflow, empty tanks or process fluctuations through precise flow control to ensure system safety and efficiency.

‌Level control valves‌ are widely used in water treatment, chemical, energy, food and pharmaceutical fields. For example, to prevent medium leakage in oil storage tanks, maintain drum water level in boilers, or ensure hygiene standards in food processing tanks. Its advantages are high precision (within ±1%), corrosion-resistant materials (such as stainless steel, PTFE) to adapt to extreme media, and energy-saving characteristics (reducing invalid cycles).
