Control Units

Safety units can be provided by La Favorite to protect the rubber expansion joint from damage caused by axial loads in the system without sacrifice in vibration isolation. This abnormal movement may also arise due to failure of a pipe support, unusually low temperatures, or incorrect anchorage of lines on the pressure side of air compressors and pumps. La Favorite control units are often used in air-conditioning systems where a wide temperature differential is encountered in normal operation. All units consist of gusset plates. These plates are then connected by means of stretcher bolts which prevent excessive extension of the rubber joint. Rubber washers backed by metal washers are placed under the bolt head and nut to dampen vibration. Excessive compression can also be controlled by this design.

Split Retaining Rings

For La Favorite joints of circular or rectangular cross section, split retaining rings are required to provide equal distribution of bolting loads. Placed directly against the rear of the expansion joint flange , they bolted through it to the companion flange. They can be supplied either black steel or plated.
