Ayvaz two-wing wafer check valves are designed to operate with minimum flow restrictions. The double spring half disc runs with the pipe fluid and reseals the rubber disk holder. It provides a return flow closed circuit. The elastic seat prevents shocks.
CV20-25 check valves are manufactured to DIN, ANSI, JIS and BS standards.

Ayvaz check valves have the following advantages over conventional isolation valves (such as swing check valves):
Low procurement costs
Compact design
Preventing impact
Light weight
Easy to install
Good flow performance with low pressure drop
Upstream fluid can flow horizontally and vertically
