Products Description
Specifications
The valve consists of a spherical ball that rests on a seating surface inside the valve body.
When fluid flows in the forward direction, the pressure lifts the ball off the seat, allowing flow.
If the flow reverses, the ball is pushed back onto the seat, effectively sealing the passage and blocking reverse flow.

FAQ
Q: What is a Ball Type Non-Return Valve?
A Ball Type Non-Return Valve is a type of check valve that uses a spherical ball as the closing mechanism to allow flow in one direction and automatically prevent backflow when the flow reverses.
Q: How does it work?
The ball inside the valve moves freely within the chamber. When fluid flows in the forward direction, it pushes the ball away from the seat, allowing passage. When flow stops or reverses, the ball returns to its seat by gravity or back pressure, sealing the passage.
Q: What are the main applications?
Sewage and wastewater systems
Pumping stations
Slurry and viscous fluid lines
Chemical industries
Fire protection systems
Q: What are the advantages of a Ball Type Non-Return Valve?
Simple design with few moving parts
Low maintenance
Suitable for dirty or viscous fluids
Quiet operation
Can handle solids in suspension
Q: Can it be installed in any orientation?
Most ball check valves are designed for vertical or horizontal installation with specific flow directions. However, vertical (upward flow) installations are generally preferred for optimal performance.
