How to use electric actuators to reduce the rotational force?

Date:Jan 20, 2019

The rotational force of the fluid vortex has a strong influence on the large V-shaped spool, which may cause the valve and the electric actuator push rod connection to be disengaged unless the joint is secure. Distortion of the diaphragm can also be caused in a springless electric actuator. In the latter case, an anti-rotation splint can be suitably attached and the extension of the valve stem can be guided.

Electric actuators can reduce the rotational force by the following methods:

1. A valve body with a streamlined design;

2. A plunger type valve core is used instead of a V-shaped valve core;

3, using a sleeve structure, because the fluid distributed along the spool is more uniform, reducing the rotational force.
