In-line check valves prevent unintended back-flow

Bio-Chem Valve has developed non-metallic, self-sealing in-line check valves for handling low volume, low flow transfers.

The inert Bio-Chek in-line check valves are available in the UK and Europe from Omnifit.

They prevent unintended liquid back-flow in high purity, low pressure fluid transfer applications and feature an even flow path that reduces passage complications.

The zero-maintenance valves are 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 valves have flow paths that are less tortuous and minimise shear and turbulence.

The valves connect to a standard 0.25 - 28 port and fitting, and provide 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 perfluoroelastomer.

PEEK and PPS are offered as housing materials.

Bio-Chem Valve is a leading manufacturer of precision metering and dispensing systems for the analytical and medical device markets.

Partnered with Omnifit, they provide a complete line of precision fluid transfer solutions.
