Inline check valve prevents liquid
back-flow
Bio-Chem Valve has developed a nonmetallic, self-sealing inline check valve for handling low-volume low-flow transfers.
Bio-Chem Valve has developed a nonmetallic, self-sealing inline check valve for handling low-volume low-flow transfers The inert Bio-Chek inline check valve prevents unintended liquid back-flow in high-purity low-pressure fluid transfer applications and features an even flow path that reduces passage complications

Speedy customisation for miniature valves
Flow control specialist Bio-Chem Valve now offers manufacturers of scientific and medical equipment a "quick-change customisation" service.
The zero-maintenance valve is available in an inlet or outlet configuration and applications include syringe pump systems, vacuum systems and other low-flow processes.
Unlike a spring-actuated check valve that can impede or restrict the flow path, the Bio-Chek inline check valve's flow path is less tortuous and minimises shear and turbulence.
The valve connects to a standard 0.25-28 port and fitting, and provides a flow rate equivalent to a 0.76mm orifice, a cracking pressure less than 0.24bar, and checks against back-flow pressure to 6.89bar.
Bio-Chem offers manufacturers of scientific and medical equipment a variety of check element materials including EPDM, Viton and Chemraz.
Peek and PPS are offered as housing materials.
