Rieger Flow Products’ BioCheck Compact sampling valve sets new standards for paramount sampling. Only one nut is necessary to disassemble the actuator from the valve body, which reduces maintenance times. The PTFE-bellow stays the same as in previous versions to keep spare parts to a minimum. A bigger hand wheel improves overall handling of the valve. BioCheck actuators in a pneumatic version with a lever and a manual version with a hand wheel are interchangeable with various body configurations.
