Unox Float Level Control Valve

What is a Level Control Valve?

Float level control valves are hydraulic control valves used to regulate the water level in storage structures such as water tanks, reservoirs, and pressure-reducing stations in transmission lines. For the main valve to open and close properly, a minimum water pressure of 7 meters in the existing network is required.

Features of Float Level Control Valve

• Its simple design makes it very user-friendly.
• The valve’s electric float is modular and can be easily installed on the structure where level control is needed.
• The electric float allows easy adjustment of the desired level control range.
• A simple control device is located between the main valve and the electric float.
• The ball valve on the main valve allows manual control of the open-close function.
• The valve operates fully hydraulically with line pressure without requiring extra energy.

Instructions for Using the Level Control Valve

• Install the valve according to the flow direction indicated by the arrow on the valve.
• For ease of service and maintenance, it is recommended to install isolation valves (gate, butterfly, or ball valves) on the inlet side to shut off the water in the line.
• To ensure efficient operation, it is recommended to install an air vent before the valve.
• Connect the electric float and solenoid valve on the main valve to the control device according to the voltage ratings.
• If connected correctly to the control unit, the valve will operate in automatic mode.
• Control valves perform open-close functions using system pressure. If the system pressure is near zero during tank filling, the valve will not operate. Check the inlet pressure value of the valve.
• To operate the valve manually, use the drain ball valve marked as 3. For automatic operation, the ball valve should remain closed.
• During winter, to prevent freezing, drain the water from the actuator to the atmosphere.
