GATE valve
Parametric studies allow you to nominate parameters for evaluation, define the parameter range, specify the design constraints, and analyze the results of each parameter variation.
Gate valves are designed for fully open or fully closed service. ... When operating the valve stem, the gate moves up- or downwards on the threaded part of the stem. Gate valves are often used when minimum pressure loss and a free bore is needed.
When handle wheel will be rotated in anti-clockwise direction, steam and gate will move in upward direction across the fluid flow line and valve will be opened from closed position and will permit the flow of fluid through the gate valve.
Construction of a Gate valve. Gate valves consists of three main parts: body, bonnet, and trim. The body is generally connected to other equipment by means of flanged, screwed or welded connections. The bonnet, which containing the moving parts, is attached to the body, usually with bolts, to permit maintenance.

CASE-1
Cross section-
Mass flow rate

CASE-2
Cross section

CASE-3
Cross section

CASE-4
Cross section

Velocity contour
conclusion- As we can see from the result of each case that increasing in mass flow rate as per gate opened 10-20-30mm.
PS- i performed 4 cases because my software keep crashing if i add more than 4 cases.
