Abstract: A pressure regulating device including a valve body, an actuator assembly coupled to the valve body and including a diaphragm, a valve seat disposed in the valve body, a control assembly operatively connected to the diaphragm to move responsive to movement of the diaphragm, and a travel stop. The control assembly includes a control element that is movable, relative to the valve seat, between an open position, wherein the control element is spaced from the valve seat, and a closed position, wherein the control element sealingly engages the valve seat. The travel stop is configured to engage the control element to stop movement of the control element upon reaching the open position. The travel stop is adjustable to change the open position of the control element, such that a wide open flow capacity of the pressure regulating device can be adjusted.

Abstract: A balanced port pressure regulator includes a valve body having a fluid inlet and a fluid outlet connected by a fluid passageway, an orifice being disposed between the fluid inlet and the fluid outlet. A valve seat is disposed within the fluid passageway. A valve plug is also disposed within the fluid passageway. A piston is disposed within the valve body, the piston separating the fluid passageway from a balancing chamber. A sleeve extends away from the piston, the sleeve forming a balancing passage that fluidly connects the fluid passageway with the balancing chamber. The sleeve includes an open end that terminates within the orifice. By terminating within the orifice, the open end of the sleeve generates boost only towards the end of a valve opening cycle when the valve plug approaches a fully open position, which is where boost is most needed.
