Spears® Tee-Style Zero-Dead-Leg Diaphragm Valve design integrates valve and Tee-fitting for direct branch take-off and eliminates the need for tees and reducing fittings normally required for service drops and other tie-ins to the loop. The Tee-Style valve provides a stronger, more compact connection enabling throttling, sampling, draining or diverting of critical process fluids. The Zero Dead-leg design is excellent for DI water and other critical applications. Close proximity of valve to mainline minimizes any areas of fluid stagnation by eliminating dead leg that can harbor bacterial growth and other contamination. Produced to order with Spigot, Socket and Threaded, or Special Reinforced (SR) Threaded end connection valve sizes 1/2 through 2 in, and specified Tee Socket connection sizes for virtually any mainline connection size.
