Double acting hydraulic actuator

I   Brief Introduction Of Double Acting Hydrauli Cactuator:

Those that open and close the valves both through power oil drive are called double acting hydraulic actuators, according to the different work environment, be divided into submerged type and dry-installation type. Submerged type can be installed under seawater up to 60m deep of seawater with long-term corrosion-resistance to sea- water. The actuators are widely used in ship building, marine engineering and marine tidalpower and other special applications.According to torque can be divided into G&R series, DHA series, Scotch Yoke series.

II   Select Double Acting Hydraulic Actuator :

The suggested safety factor for double acting actuators under normal working conditions is 20%-30%.

Forexample：

The torque needed by valve=100N.m

The torque considered safety factor=100×(1+30%)=130N.m

Oil pressure supply=7Mpa

According to the above table,we can choose the minimum model is F4-011P-DA50
