          Week 9 - Parametric study on Gate valve.

          Objective:

          PARAMETRIC STUDY ON GATE VALVE INTRODUCTION A gate valve, also called sluice valve, often installed in a pipe fitting, opens by lifting a barrier called gate out of the path of the fluid. Gate valves require very little space along the pipe axis and hardly restrict the flow of fluid when the gate is fully opened. The gate…
