Manual shut-off valve design analysis

The cut-off valve body is the main pressure parts of the valve, and accommodate the closure member. The cut-off the flow passage within the valve is designed to have a smooth arc wall without sharp corners and sharp edges, which provides a smooth process flow does not generate abnormal turbulence and noise.

Flow channel itself must have a constant area in order to avoid any additional pressure loss and high flow rate. Cut-off valve having two wider end portion is connected, so the valve body can be applied in almost every kind of end connection, despite the flangeless structure to adapt to its face-to-face dimensions is too long (bolt connection between the two pipeline flanges valve body in the rotary valve, which is common). The shutoff valve, the end portion does not match the connection is also possible.
