KOSCN PV317 Pilot Pressure Reducing Valves

The PV317 series pilot-type pressure reducing valve stabilizes variable pressure in chemical liquid and pure water systems through air source control. It ensures consistent downstream pressure by balancing pressure pulsations, offering stable, low-vibration control with excellent repeatability. This valve supports automatic control for applications like pulsation prevention, constant pressure supply, and precise dosing.
