                                QR-S Mechanical Damping Device
	Set pressure adjustable with QR-S installed
	Rated to 25 psig MAOP
	Compatible with combustion regulators 121 and 122 and Commercial 243
                        
	Improve pressure control on commercial and industrial operations and enhance the speed of response on pressure regulators with the Sensus QR-S mechanical damping device.
	This patent-pending device lowers your energy cost with high-efficiency burners and boilers. By simply removing a regulator’s spring tower cap and installing the QR-S in its place, this device prevents high lock-up or excessive pressure-drop conditions. It can be installed on new products or retrofitted to existing products already installed.
