The Series S77 Sanitary butterfly valve is made of stainless steel 304 for resistance to corrosion and high temperatures. It has a 4 Position handle, Viton seat, stainless steel 304 disc, and tube OD quick clamp connections on both ends. The valve has a precision milled body, with all wetted parts polished to a 180 grit. The disc is made of stainless steel 304, which resistance to corrosion and high temperatures. Viton seat provides extreme temperature and chemical resistance. The 4 position handle...

Used in commercial grove-end piping systems. The uniqueness of Gruvlok° Butterfly Valve begins with the spherical bore of the disc seat. This facilitates a constant Disc-to-Seat loading that maintains a leak tight stem seal regardless of disc position. The stem sealing force is constant through the full disc cycle and operating torques are kept low which increases valve life. The design provides a buble tight seal from full vacuum to 300 psi when the valve is closed. The valve is rated for dead-end...
