Since 2001 Checkfluid has made it easier for companies to get reliable oil samples by developing oil sampling valves and related hardware. Checkfluid’s sampling valves are designed to make sampling both pressurized and non-pressurized systems easier and more precise. A one-time installation provides a significant return on investment; sample after sample, year after year. Checkfluid valves are designed, machined, and assembled according to rigid ISO 9001:2015 guidelines and often can be specified on new purchases.
