LowFlow is a leading manufacturer of fractional flow valves. Their unique rolling diaphragm actuator design ensures the surface area of the diaphragm remains constant throughout the entire stroke of the valve.

LowFlow sizing software specifically addresses dynamic flow conditions typical of metering and injection applications, and LowFlow positioners are designed to address your specific accuracy or rangeability requirements, even in difficult environments.
