IPEX VKD Series Ball Valves offer a variety of advanced features such as the patented seat stop carrier, a high quality stem and ball support system, and a multifunctional handle with optional lock. The new DUAL BLOCK® system locks the union nuts preventing back-off due to vibrationor thermal cycling. Deep grooves, thick o-rings, and cushioned Teflon® seats contribute to strong seals under pressure while integral mounting features and bracketing combine for simple adaptation for actuation and anchoring. Pressure rated to 232 psi at 73°F. Sizes 3/8″ to 4″.

Flow Coefficients
Flow coefficients (CV) = flow rate in gallons per minute of
water at 68°F that will flow through the valve with a 1 psi
pressure drop. The CV values shown in the table are
calculated with the valve fully open.
