Frequently Asked Questions
❓What is a ball type check valve and how does it work?
A ball type check valve uses a movable ball inside the valve body to control flow direction. When fluid flows in the correct direction, the ball is pushed away from the seat, allowing flow to pass. When flow reverses or stops, the ball is pushed back onto the seat by gravity or back pressure, sealing the valve and preventing reverse flow.
❓What materials are available for the ball type check valve?
Our ball type check valves are available in ductile iron (DI), cast iron, and stainless steel. The standard configuration uses a ductile iron body and bonnet, carbon steel bolts, and EPDM sealing components, making them suitable for water, wastewater, and various industrial fluid applications.
❓Can the ball type check valve be installed horizontally and vertically?
Yes. The ball type check valve supports both horizontal and vertical installation orientations. Its compact design requires minimal space, making it highly adaptable for various pipeline configurations in water treatment plants, sewage systems, and industrial facilities.
❓Is the ball type check valve suitable for wastewater or slurry applications?
Absolutely. The ball type check valve is specifically designed for media containing suspended solids, slurry, or fibrous materials. Its self-cleaning ball seat design prevents clogging and buildup, making it an ideal choice for sewage pipelines, wastewater treatment systems, and chemical processing environments.
❓What pressure ratings are available for the ball type check valve?
Our ball type check valves are available in PN10 and PN16 pressure ratings. Dimensional specifications for both pressure classes across a range of nominal diameters (DN50 to DN600) are provided in the dimensions table above, ensuring you can select the correct valve for your system requirements.
❓What size range is available for the ball type check valve?
The ball type check valve is available in nominal diameter sizes ranging from DN50 to DN600, covering a wide range of pipeline applications. Each size is available in both PN10 and PN16 pressure ratings with corresponding flange dimensions to ensure compatibility with standard pipeline systems.
