Saunders Zero Dead Leg ‘Tee’ Pattern Diaphragm Valve

The Zerostatic Tee valve combines a single weir with a tee pattern body. This design eliminates the dead leg present when a 2-way valve is welded or clamped to a tee fitting and has become a BioPharm standard. Essential for the elimination of dead legs in recirculating loops and designed to ease installation and validation. Available from FlowTherm, the Saunders® Zerostatic Tee Valves enhance the integrity of critical systems.
