PVDF Diaphragm Valves are used in medical, pharmaceutical, cosmetic, research and other high-purity liquid transportation applications where the highest-quality systems are required. Diaphragm valves consist of a valve b...
Check valves only allow flow in one direction and, as such, are similar in operation to electronic diodes. The simplest construction is the ball and seat arrangement of the valve, commonly used in pneumatic systems. The ...
