47/48 Series pneumatic Single-Seated Control Valve
The 47/48 Series pneumatic Single-Seated Control Valve is composed of 2 parts of ∑ F actuator
And 21000 series single-seated control valve.
∑ F actuator is a actuator with large output thrust, and it has 3 sizes of ∑ FA, ∑ FB and ∑ FC.
This kind of actuator is composed of spring-diaphragm actuator and a force Amplification Sysytem.
It magnifies the output force of the actuator 2.6~5.2 times by utilizing lever amplification
Principle. The main parts of the actuactor are upper diaphragm case, lower diaphragm, diaphragm spring,
Yoke, and a set of lever assembly.
