The body of ball check valve can be made of different materials such as cast iron, cast steel, stainless steel, etc. according to the working conditions. The valve disc can be made of rubber coated steel balls, EPDM ball, PTFE ball, etc., which can adapt to different pressures, temperatures, and media types.
Advantages
Extremely Low Flow Resistance & Significant Energy-Saving Effect
The DI ball check valve adopts a streamlined full bore flow channel design, with no unnecessary protrusions to hinder fluid flow. The loss is much lower than that of swing check valve and lift check valves, reducing about 50% compared to similar products.
Long-Term Use & Cost Savings
In long-term operation, this ball type one way valve can reduce the energy consumption of the conveying pump and reduce pipeline operating costs. It is especially suitable for high flow, long-distance pipeline use, balancing high efficiency and energy conservation.
Fast Closing Speed Effectively Suppresses Water Hammer
The ball type shutoff valve relies on the dual effects of the gravity of the sphere and the reverse pressure of the medium. The sphere can quickly fall back to the valve seat, achieving instantaneous closure and avoiding water hammer impact caused by medium backflow.
Packing
Standard export wooden case packaging
Application Scenarios
The ball non return valve is widely used in complex working conditions such as sewage treatment, industrial wastewater, and mine water supply and drainage. Its core function is to prevent fluid backflow, protect pipeline systems and equipment safety.
Frequently Asked Questions
Q
What materials are available for the ball check valve body?
The valve body can be manufactured from cast iron, cast steel, or stainless steel, depending on the specific working conditions and media requirements of your pipeline system.
Q
What types of valve disc materials are available for the ball check valve?
The valve disc can be made of rubber-coated steel balls, EPDM balls, or PTFE balls. Each material is suited to different pressure ranges, temperature conditions, and media types, ensuring versatility across applications.
Q
What is the operating temperature range of this ball check valve?
The ball check valve is designed to operate within a temperature range of 0°C to 80°C, making it suitable for a wide range of industrial and municipal water applications.
Q
How does the ball check valve help prevent water hammer?
The valve relies on the dual effects of the sphere's gravity and the reverse pressure of the medium to quickly return the ball to the valve seat. This achieves instantaneous closure, effectively suppressing water hammer caused by sudden fluid backflow.
Q
What are the main application scenarios for the ball non-return valve?
The ball non-return valve is widely used in sewage treatment plants, industrial wastewater systems, and mine water supply and drainage systems. It is ideal for any application where preventing fluid backflow and protecting pipeline equipment is critical.
Q
How does this ball check valve compare to swing and lift check valves in terms of energy efficiency?
Thanks to its streamlined full bore flow channel design, the DI ball check valve produces significantly lower flow resistance than swing or lift check valves. It reduces energy loss by approximately 50% compared to similar products, making it an excellent choice for high-flow, long-distance pipeline systems.
