Wafer-Style Butterfly Valve
The wafer-style Type 567 polypropylene butterfly valve is now available in sizes 14 in. to 24 in. Its double-eccentric, off-center design reduces friction and wear for longer life. It requires only about half the torque of a traditional boot design, also reducing wear on the disc seal for longer product life. Pressure ratings at 70 ºF are 90 psi for sizes 14 in. to 16 in.; 75 psi for size 18 in.; and 60 psi for sizes 20 in. to 24 in. Additional features include industry-standard ISO flange mount, bi-directional capability and hand wheel.
