It is best to consult the manufacturer regarding this; different manufacturers and different models have varying differential pressures
The maximum shut-off pressure difference depends first on the characteristics of the valve, as well as on the process conditions.
The closing pressure difference of a single-seat control valve is usually determined by the manufacturer based on design and materials. Generally, the closing pressure difference range for most single-seat control valves is between 10 and 15 bars. However, the specific closing pressure difference needs to be determined based on the valve’s model and specifications; therefore, it is best to refer to the specific product manual or consult the manufacturer to obtain the exact closing pressure difference limits. .
Close the pressure difference and consider the type of valve (it can be plunger-type, rotary-type; even an O-ring ball valve can be used as a control valve). Different valve types require different calculation methods
