I Model and specification of linear hydraulic actuator
1. Demonstration of the type
2.Select the size of the hyrdaulic actouator according to the output force of the open &close valve.
Double acting linear hydraulic actuator selection
The suggested safety factor for double acting linear hydraulic actuator under normal working conditions is 20%-30%.
For example：
The thrust needed by valve=10KN,valve travel is 100mm
The thrust considered safety factor=10×(1+30%)=13KN
Oil pressure supply=10Mpa
According to the thrust parameters of double acting linear hydraulic actuator ,we can choose the minimum model is FYG-DA40/18X110
II. Thrust parameters of FYG-DA type linear hydraulic actuator
1. Thrust parameters of FYG-DA type linear hydraulic actuator ( include 95% efficiency coefficient)
Remark: “S” on behalf of the actuator stroke
2. Overall dimensions
A. FYG-DA series type A installation model (general)
Remark: “S” on behalf of the actuator stroke
B、FYG-DA series B installation mode (special for globe valve)
Remark: “S” on behalf of the actuator stroke
C、FYG-DA series C-type mounting mode (single exit shaft with valve support)
Remark: “S” on behalf of the actuator stroke
