Valve and valve control method |
摘要 |
A vacuum actuated valve uses a specially designed spring having a spring rate as a function of valve position. The spring rate function is determined using physical relationships between flow, pressure, and valve s position. The result is that the relationship between the control input to the valve (either a vacuum signal, or an electrical signal to a vacuum source) and the flow through the valve are linearly related through the entire operating region of the valve.
