Abstract
The invention generally provides a static back pressure regulator. In exemplary embodiments, the static back pressure regulator includes a seat that defines part of a fluid pathway, a poppet, a spring arranged to bias the poppet toward the seat to restrict fluid flow through the fluid pathway, and a calibration element configured to adjust a force applied to the poppet by the spring. The calibration element can include a through hole that forms part of the fluid pathway. The poppet can include a first guiding portion that extends into the through hole of the calibration element and inhibits tipping of the poppet relative to the seat.
