Stainless Steel Hydraulic Float Valve DN50-DN200 Automatic Water Tank Level Control Valve

Product Overview

The Hydraulic Water Level Float Valve is a pilot-operated diaphragm valve designed for automatic water level control in tanks and reservoirs. It integrates a main valve, a regulating needle valve, and a float pilot valve. As the water level changes, the float rises or falls, piloting the main valve to open or close, thereby maintaining a preset water level without the need for external power. This valve features precise control, stable operation, et longa opera vitae. Available in a wide range of materials including ductile iron, cast steel, and stainless steel to suit various water quality conditions.

FAQ

Q1: Can this float valve be used for seawater or corrosive media?
A1: The standard configuration is for fresh water. For seawater or mildly corrosive media, we offer customization with full stainless steel (316L) body and special sealing materials.

Q2: How to select the correct valve size (DN) for my tank?
A2: Size selection is determined by the inlet pipe diameter, required flow rate, and working pressure. Fere, the valve size matches the pipeline. Please provide your operating parameters, and our technical team will assist with selection.

Q3: What could cause the valve to fail to close or leak?
A3: Common causes include: 1) Stuck or damaged float; 2) Clogged needle valve; 3) Damaged diaphragm. Regular cleaning of the strainer and inspection of the float movement are recommended. Contact after-sales for a repair kit if the issue persists.

Q4: What is the maximum working temperature?
A4: The standard model operates at 0°C ~ 80°C. For higher temperatures (e.g., hot water systems), please consult us for high-temperature sealing materials.

Q5: What installation precautions are needed?
A5: 1) Flush the pipeline before installation to prevent debris from entering; 2) Mount the float horizontally inside the tank to ensure free movement; 3) Install a strainer and isolation valve upstream for maintenance access.
