Lever Wafer Concentric Butterfly Valve Rubber Lined Disc

The lever wafer butterfly valve of Waits Valves is a low cost flow control device that can supply cut-off and throttling functions in medium and low pressure systems. It allows a compact wafer type valve body, which is convenient for installation between flanges and is equipped with a manual lever or gear operating mechanism. It is also covered with an elastic rubber lining (usually ethylene propylene diene monomer (EPDM), nitrile rubber (NBR) or other elastomers), which can make the valve body airtight and protect it from corrosive media erosion. The valve disc rotates 90 degrees to control the fluid flow with minimal pressure drop and torque.
