Azbil Corporation No. SS2-AGV200-0300 - 7 - 3-2 Actuator 3-2-1 Actuator and valve actions Table 5 Specification of actuator Note) *: The travel transmission is a standard specification for the proportional control, but that is a optional spcification for the two position control. Valve action The valve action is decided by selecting the operation of the actuator action. Signal to open: actuator action where the valve opens as the input signal increases Signal to close: actuator action where the valve closes as the input signal increases 3-2-2 Tables of allowable differential pressures Ensure the required shut-off differential pressure specified in the equipment design is satisfied by selecting an actuator with an allowable differential pressure equal to or higher than the shut-off pressure, according to the seat leakage class. Seat leakage, Class IV (0.01% of rated Cv value) . Model AGVB: Table 6-1 and 6-2 on page 8 . Model AGVM: Table 6-3 and 6-4 on page 8 Seat leakage, Class VI (high shutoff model: soft seat) . Model AGVB: Table 7-1 and 7-2 on page 8 . Model AGVM: Table 7-3 and 7-4 on page 8 3-2-3 Finish The normal standard coating color for Azbil Corporation's control valves is blue (Munsell 10B 5/10). Silver is also available as standard. Standard colors are also used for such optional accessories as positioners, pressure regulator with filter, and solenoid valves. 4. Fluid Conditions It is important to make the fluid conditions clear in selecting the control valve. Please fill in each data on “Fluid specifications” column in the lower of the model selection table. Calculation of the Cv values and expected noise For calculation of the Cv values and expected noise, refer to following document. Selecting the control valves: No. IB2-8000-0100 Azbil Corporation has developed personal computer software to calculate Cv values and expected noise. Please specify if you require such a PC-based tool.

Operation speed (open .. close) 16 sec. . With the Alphaplus, the valve closes as the plug lowers. The valve action depends, in turn, on whether an signal to close or signal to open actuator is chosen. . When the power supply is “Stop”, the actuator keeps the travel transmission of that time. You can specify any other color using the number code of the Japan Paint Industry Assignment or the Munsell color system.
