Check Valves - Apollo Valves
Check valves are essential flow control devices that allow fluid movement in one direction while preventing backflow. These self-activating valves enhance system efficiency, reduce pressure loss, and protect equipment in various industrial and commercial applications.
At Centro, we offer a comprehensive selection of check valves built for durability and performance. Whether you need swing check valves for irrigation systems, sump pump check valves to prevent water backflow, or compressed air check valves for pneumatic systems, we have the right solution for your application.
Types of Check Valves We Offer:
- Swing Check Valves – Ideal for irrigation and low-pressure systems
- Ball Check Valves – Reliable for wastewater and slurry applications
- Piston Check Valves – Designed for precise flow control in hydraulic systems
