FAQ
Q: What is a ball type check valve?
A ball type check valve is a non-return valve that uses a ball as the closing mechanism. The ball moves freely within the valve body and seals against a seat to prevent backflow when flow stops or reverses.
Q: What is the valve body made of?
The body is made of ductile iron, which offers:
High strength
Excellent impact resistance
Better corrosion resistance than cast iron
Q: How does it work?
When fluid flows in the forward direction, pressure lifts the ball off the seat. When flow stops or reverses, the ball returns to the seat by gravity or reverse flow pressure, sealing the valve.
Q: Can it be used in vertical pipes?
Yes, ball check valves made of ductile iron can be installed in both horizontal and vertical (upward flow only) positions.
Q: What sizes are available?
Commonly available in sizes ranging from DN50 to DN300 (2" to 12"), but can vary by manufacturer.
