Description
Cepex clear series check valve - Ø 63 mm with spring
Cepex clear series check valve Ø 63 mm with spring is a robust and transparent PVC check valve that prevents water from flowing back into your piping. Thanks to the built-in spring, the valve closes actively and quickly as soon as the water flow decreases. This makes this version particularly suitable for larger installations with 63 mm pipework, where stability and reliable sealing are essential.
The transparent housing allows you to immediately see whether the valve opens and closes correctly and whether there is dirt or air in the pipe. This makes inspection and maintenance a lot easier.
Spring loaded operation for extra security
In contrast to a standard gravity valve, this version closes by means of an internal spring. This actively prevents backflow even at low flow or slight pressure differences. This is especially important at:
- Heat Pumps
- Salt electrolysis systems
- Automatic dosing systems
- Installations with height difference
The spring ensures a faster and more reliable closure when the pump stops.
Transparent design for visual control
The clear series is designed for technical areas where control is important. Thanks to the transparent body, you can check without disassembly if:
- The valve moves freely
- There is no blocking
- The flow direction is correct
This saves time in troubleshooting and maintenance.
Installation in 63 mm PVC piping
This check valve is designed for gluing in standard 63 mm PVC pressure pipes. When mounting, always pay attention to the flow arrow on the housing and make sure the pipes are connected tension-free. Preferably mount in an easily accessible location.
When adding an automatic dosing system, it is important that it is correctly positioned in the installation to avoid unwanted backflow towards other components.
