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.
