Dwyer WE20-FHD00-LE | CAPP

Dwyer WE20-FHD00-LE Butterfly Valve, 6.0 Inch. Lug Connection, EPDM Liner, Manual Hand Lever. Ductile Iron. This Series WE20 Butterfly Valve features a lug body style equipped with a EPDM liner and Manual Hand Lever. The most critical aspect of the Series WE20 Butterfly Valves is the cartridge seat design, which alleviates installation problems associated with common "dove tail design" seats. Valve torques are lower and more consistent as the seat dynamics are not dependent on being coupled between two flanges. Precision machining of the disc and body allow the cartridge design to maintain a tighter disc to seat tolerance, providing a perfect low torque seal each and every time the valve is cycled. The seat to disc seal is independent of flange support and capable of full rated dead end service. SPECIFICATIONS: Service: Compatible liquids, gases, and steam. Body: 2-way, lug butterfly.
