Check valves - Reliable safety and protection for your pipework systems
Welcome to the check valves category, your specialist for high-quality and reliable valves that prevent backflow and increase the efficiency of your pipework. Whether you operate a swimming pool, irrigation system or industrial plant, our check valves ensure that your systems function smoothly and safely.
What are check valves?
Check valves, also known as non-return valves, are mechanical devices that prevent the backflow of liquids in pipework. They open with forward flow and close automatically when the pressure decreases or the flow starts in the opposite direction. These valves play a crucial role in preventing damage to pumps, filters and other components.
Advantages of our check valves
Our non-return valves offer numerous advantages that make them an indispensable component for your installations:
- Backflow prevention: effective protection against backflow and contamination.
- Robust materials: Made from durable PVC, which is corrosion-resistant and hard-wearing.
- Reliable function: Automatic opening and closing for maximum efficiency.
- Simple installation: Quick and easy to install.
- Cost-efficient: Outstanding quality at an attractive price-performance ratio.
Areas of application
Non-return valves are indispensable for various applications:
- Swimming pool technology: Protecting pump and filter systems from backflow.
- Irrigation systems: Ensuring the flow of water in agricultural or horticultural projects.
- Industry: Efficient control of fluid flows in chemical and technical systems.
- Drinking water and waste water systems: Hygienic and safe solutions for the protection of sensitive areas.

PVC Pipe Check Valve with 2x Glue Sleeves – Reliable Solution for Controlled Flow The PVC pipe check valve with 2x glue sleeves offers an efficient way to prevent backflow in piping systems. The integrated spring securely holds the check valve in place, ensuring precise control while slightly reducing the flow. Made from durable PVC, this high-quality valve is ideal for applications in water technology and other installations where reliable flow control is required. Features: Connections: 2x glue sleeves for stable and secure connections Mechanism: Spring-supported check valve for effective backflow prevention Material: Durable PVC for maximum corrosion resistance Benefits: Easy installation, reliable function, and flexible application options With this check valve, you are choosing safety and quality to efficiently control and protect your piping systems.
PVC Pipe Check Valve Transparent with Coupling – Efficient Backflow Control for Professional Applications The transparent PVC pipe check valve with coupling is the ideal solution for precise backflow control in piping systems. It is compatible with pipes in DIN sizes 63, 75, and 90 mm and, due to its transparent design, allows easy visual monitoring of the flow. The 110 mm check valve is delivered without a coupling and must be firmly glued in place. The check valve only minimally reduces the flow. To prevent a total flow loss, a larger check valve with a matching reducer ring can be used. For example: For a 50 mm pipeline, use the check valve Ø63 mm with a 63/50 reducer ring to ensure unobstructed flow. Features: Compatibility: Suitable for DIN 63, 75, and 90 mm pipes (110 mm requires gluing) Design: Transparent construction for easy flow control Efficiency: Minimal flow reduction with adjustment options for optimal flow Installation Size: Ø50 – Installation height 21 cm Ø63 – Installation height 25 cm Ø90 – Installation height 33 cm Ø110 – Installation height 25 cm This professional PVC check valve combines functionality, efficiency, and durability, making it perfect for demanding installation projects.
