Linear double acting hydraulic actuator

产品详情

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

III. Single acting linear spring return electro-hydraulic actuator physical reference figure
