T-343 Zero-Deadleg Diaphragm Valve (PVDF, PPn, and PP)

For branches and laterals, our T-343 zero dead leg diaphragm valves (ZDLs) eliminate dead space where bacteria can grow. Valves are cleanroom produced, assembled and packaged. All valves come standard with integral lockout device to prevent unauthorized cycling. Valves are 150psi rated at 68° F and designed for high temperature service. Fully serviceable with replacement diaphragms available.
