An improved adjustable fluid flow regulator having a regulator chamber, a moveable diaphragm within the regulator chamber, a spring that acts upon the diaphragm to regulate the flow of fluid, and a first adjustment member and second adjustment member for adjustably biasing the spring against the diaphragm. The improvement includes a tamper resistant feature for restricting adjustment above a predetermined limit. The first adjustment member is fully adjusted to a limit. The second adjustment member is adjusted to bias the spring to a predetermined maximum setting, and restricted from further adjustment. The first adjustment member would subsequently be adjustable to any setting up to the predetermined limit.
An adjustable fluid flow regulator having a regulator chamber, a moveable diaphragm therein, and a spring that acts upon the diaphragm to regulate the flow of fluid through the regulator, the improvement comprising:
A method of adjusting a fluid flow regulator of the type having a regulator chamber, a moveable diaphragm, a spring that acts upon the diaphragm to regulate the flow through the regulator, and a first adjustment member having a second adjustment member disposed therein for adjustably biasing the spring against the diaphragm, the method comprising the steps of adjusting the first adjustment member to a fully adjusted position;
A method of adjusting a fluid flow regulator of the type having a regulator chamber, a moveable diaphragm, a spring that acts upon the diaphragm to regulate the flow through the regulator, and a first adjustment member having a second adjustment member disposed therein for adjustably biasing the spring against the diaphragm, the method comprising the steps of adjusting the second adjustment member to a fully adjusted position;
The method of adjusting from a first operating pressure to a second operating pressure for an adjustable fluid flow regulator of the type having a regulator chamber, a moveable diaphragm, a spring that acts upon the diaphragm to regulate the flow through the regulator, and a first adjustment member having a second adjustment member disposed therein for adjustably biasing the spring against the diaphragm, the method comprising the steps of removing the first adjustment member from the regulator chamber without altering the second adjustment member;
