Typical flow characteristic curves
Allowable pressure difference
I. LHA or LVA actuators for valves
A. gas shut valve 100kPa
B. gas open valve 100kPa
Note: P=P1(P2=0) is the condition of allowable pressure difference when the table is closed. The pressure difference at full closure varies slightly with the outlet pressure P2.
Maximum allowable differential pressure shall not exceed the maximum working pressure specified in ANSI B16.34-1981 or JIS B2201-1984 standards
The inlet pressure P1 shall not exceed the allowable pressure difference when the valve is closed.
* the number above the same grid indicates the allowable pressure difference, and the lower figure indicates the allowable pressure difference.

II. Valve equipped with LVP actuator 100kPa
Note: If the actuator has an auxiliary gas source, the smaller one of the two should be selected as the basis for calculating the allowable pressure difference.
The condition of allowable pressure difference is P=P1 (P2=0) when the table is closed. The pressure difference at full shutdown varies slightly with the outlet pressure P2.
Maximum allowable differential pressure shall not exceed the maximum working pressure specified in ANSI B16.34-1981 or JIS B2201-1984 standards
The inlet pressure P1 shall not exceed the maximum allowable pressure difference when the valve is closed.
* the number above the same grid indicates the allowable pressure difference, and the lower figure indicates the allowable pressure difference.
