The Betts WD601ALU001 is a 6-inch manually operated TTMA detent Wet-R-Dri butterfly valve featuring an aluminum body with epoxy coating and black urethane disc seal. This quarter-turn in-line stop valve provides a positive stop in both open and closed positions, with a detent spring and ball mechanism that assists in holding the disc securely. The epoxy-coated body offers enhanced chemical resistance and extended service life for water applications. With a maximum working pressure of 50 psi and operating temperature range from -40F to 200F, this valve handles liquid, gaseous, and dry products. The bolt pattern matches TTMA piping flange dimensions for straightforward installation.
