Abstract
A valve assembly, includes a valve body having an inlet portion, an outlet portion, and a constriction portion; a shaft positioned within the valve body and extending along a longitudinal axis of the valve body; a cone provided within the inlet portion and configured to move along the shaft; a spring configured to bias the cone away from the constriction and positioned between a first piston fixed to the cone and a second piston fixed to the shaft; and an adjustable spacer positioned between a fixed position on the shaft and the second piston. The adjustable spacer is adjustable in length to change an effective length of the adjustable spacer and change a position of the second piston on the shaft.

A valve assembly, comprising:
- a valve body comprising an inlet portion, an outlet portion, and a constriction portion;
- a shaft positioned within the valve body and extending along a longitudinal axis of the valve body;
- a cone provided within the inlet portion and configured to move along the shaft;
- a spring configured to bias the cone away from the constriction portion and positioned between a first piston fixed to the cone and a second piston fixed to the shaft;
- and
- an adjustable spacer positioned between a fixed position on the shaft and the second piston, the adjustable spacer configured to be adjustable in length to change an effective length of the adjustable spacer and thereby change a position of the second piston on the shaft.
