Ball check valve CVD13 series

weldfemalebackflow

Short description
Check valve with BS female socket for solvent welding, manufactured in UPVC for corrosion-resistant pipeline applications.

Product family
UPVC VALVES - Check Valves

Key information

• Type: Check Valves
• Brand: U-PVC Check Valves
• Material: UPVC
• Connection: BS female socket for solvent welding
• Pressure rating (PN): see variants (typically 10–16)

Summary
Compact UPVC check valve CVD13 designed to prevent backflow in water and chemical piping systems. Installation is by solvent-weld into a BS female socket, providing a secure, leak-minimising joint. Available in multiple nominal diameters to match standard pipeline sizes.
