Valve throttling for pressure reduction

2012-06-01View Original

Thread Content

There is a valve on our raw material gas pipeline before it enters the cyclone; the pressure before the valve is 7.5 MPa, and the pressure after the valve is 5.6 MPa. The diameter of the pipe remains unchanged. What is the principle behind this? Can any valve be used?

The pressure drop is controlled by changing the valve opening, as far as I understand it
