Differential pressure is measured on each side of the regulation accuracyThe regulation function presents an optimize ac-curacy thanks to a screw-down globe valve present ideal regulation properties through equal percentage characteristic curve up to a stroke of 45% (linear characteristic curve in the regulating range above stroke > 45%).Stroke limiter The stroke limiter allows the setting memorization before isolation for instance: when reopening the valve, the setting is easily recover. The setting memorization can be sealed thanks to a locknut. The stroke limiter is protected by a protection long lasting The seat sealing is made of PTFE and carbon which has shape memory features.
