Overview:

YFLJX series restrictive orifice plate is concentric sharp orifice plate, which is used to restrict the flow of fluid or reduce the pressure of fluid. Fluid passing through the orifice will produce a pressure drop, and the flow through the orifice will increase as the pressure drop increases. However, when the pressure drop exceeds a certain value, that is, the critical pressure drop is exceeded, no matter how the outlet pressure decreases, the flow rate will maintain a certain value without increasing. The restriction orifice is used to limit the flow of the fluid or reduce the pressure of the fluid according to this principle.

Product advantages:

1.Can limit the flow

2.Can reduce stress

3. Simultaneous current limiting and voltage reduction

4. No need to take pressure hole to measure differential pressure
