Bio-Chem Valve has developed a non-metallic, self-sealing in-line check valve for handling low volume, low flow transfers. The inert Bio-Chek™ in-line 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.
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™ in-line check valve’s flow path is less tortuous and minimises shear and turbulence.
The valve connects to a standard ¼ – 28 port and fitting, and provides a flow rate equivalent to a 0.76mm orifice, a cracking pressure less than 0.24 bar (3.5 psi), and checks against back-flow pressure to 6.89 bar (100 psi). 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.
