Ayvaz dual flap wafer check valve is designed to operate with the minimum flow restriction. The twin spring loaded half disc operates with the pipeline flow and reseal back against the rubber disc seating. It is providing a positive shut off against any back flow. The resilient seating prevents a slamming action.
ÇV20-25 check valves are produced according to DIN, ANSI, JIS and BS standards.

Ayvaz check valves when compared with order traditional isolating valve such as swing check valve offer the following advantages:

Low purchase cost
Compact design
Non-slam principle of operation
Light weight
Easy installation
Good flow characteristic and less pressure drop
Suitable for horizontal and vertical up flow
