Zero Static Tee Block Valve

Applications:

Single Weir zero static use point for manual on/off air actuated flow control for transfer or diversion of drug process additives, WFI and other critical system fluids.

Upstream:

• Bioreactor/fermenter: for sampling or transfer of critical process fluids, inputs or WFI upstream of, and prior to opening the main valve.

Downstream:

• For sampling or transfer or critical fluids, buffers or WFI upstream of and prior to, opening the main valve in the following areas: separation, filtration, chromatography, formulation, fill finish

Buffer and media prep:

• For sampling or transfer of critical process fluids, buffers or WFI upstream of, and prior to opening main valve

Available sizes:

• Inlet and outlet: 1/2″ – 4″ (DN15 – DN100)
• Drop Connection: 1/2″ – 4″ (DN15 – DN100); drop connection must be < = the run connection

Connection type: tri-clamp, extended tube end standard. Other drop connection types available upon request. Additional ports or tandem access configurations available as special options
