  • Pressure regulating device having a variable travel stop
    Patent number: 10520957
    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.
