8. Passive check valve mp-cv
When the micropump is switched off, a back flow of the pumping medium, depending on a differential
pressure between in- and outlet is possible. In order to impede a back flow Bartels Mikrotechnik offers a
passive check valve integrated in stainless steel.
The connection of the valves with the micropump can be done easily with suitable tubing. The valve should
be placed between the micropump and the outlet reservoir.
Dimensions:
The valves are individually marked regarding the free flow direction.
Technical specifications:
Please note that the volume flow of the micropump will be influenced by the check valve.
