Differential pressure regulating valve (Δp regulating valve) (differential pressure valve) keeps the pressure difference between two points of a system at a constant level according to the value we set. Flow limiting balancing valve (cut-off and pre-setting valve) adjusts the flow rate of the fluid transmitted to the part of the system controlled by the pressure regulating valve. It provides the opportunity to adjust in accordance with the predetermined design flow rate values, and prevents the system from being damaged in variable flow rate systems.
In the differential pressure adjustment valve (Δp adjustment valve), the Δp value gives the difference between the pressure values. The pressure value set at a certain level is automatically kept constant at a certain level by the diaphragm after the pressure in the valve is connected to the capillary tube. This value that is kept constant is the Δp value.
