Sterile Access Block Valve

Applications:

Single block valve with single or double sterile access valves for manual on/off or air actuated flow control for transfer, diversion or sample 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 of critical process 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 the main valve.

Available sizes:

• Run connections: 1/2″ – 4″ (DN15 – DN100)
• Access port connection: 1/2″ – 4″ (DN15 – DN100); drop connection must be <= the run connection

Connection type:

• ASME BPE Tri-clamp, extended tube end standard. Additional connection types available as options upon request.
• Sample port configurations available as special options

Materials:
