Product Features
High-precision control: The ball valves for flow control can achieve precise adjustment of the water level, ensuring the stable flow of liquid within the set range, effectively avoiding the problem of water tank overflow or low water level.
Corrosion-resistant materials: The valve body is usually made of corrosion-resistant materials such as stainless steel, plastic or copper, which can adapt to various water quality conditions and ensure reliability and safety in long-term use.
Full-bore design: The full-bore structural design of the ball valves for flow control minimizes fluid resistance and has a large flow rate, reducing the load on the water pump and improving the working efficiency of the system.
FAQ
1.How to choose a suitable water level ball valve?
When choosing, factors such as media type, working pressure, temperature, flow requirements and installation environment should be considered.
2.What control equipment can the flow control ball valve be used with?
It can be used with water level sensors, float switches and PLC control systems to achieve the purpose of automatic water level control.
3.What is the sealing performance of the water level ball valve?
High-quality ball valves usually have good sealing performance, which can effectively prevent leakage and ensure safe operation.
4.How to maintain the flow control ball valve?
Regularly check the valve body and sealing surface, remove dirt and sediment, and ensure that the valve is not stuck when switching.
5.Is there any restriction on the installation position of the ball valve?
Ball valves can generally be installed horizontally or vertically, but the flow direction of the valve should be ensured to meet the design requirements.
