The degree of angular movement is based on the maximum rated extension. DISTRIBUTED BY: (mm)/Inch 2. Torsional movement is expressed when the expansion joint is a neutral length.Designed To Absorb Different 3. To determine "end thrust", multiply thrust factor by operating pressure of system. Movements Concurrently. 4. Pressure rating is based on 170�F operating temperature. At higher temperature the pressure rating is slightly reduced. 5. Weights are approximate. 6. Control unit weight consists of one rod, four washers, three nuts and two control rod plates. Multiply number of control units needed for application (as specified in the Fluid Sealing Association Technical Handbook) to determine correct weights. 7. Dimensions shown are in accordance with 125/150# standards of ANSI B-16.1,Axial CompressionAxial Elongation B-16.24, B-16.5; AWWA C-207 Table 1 and 2 Class D.

Normal precautions should be taken to make sure these parts are installed correctly and inspected regularly. Precautions shouldbe taken to protect personnel in the event ofleakage or splash. Note: Piping mustbe properly alignedand anchored to prevent damage to an expansion joint. Movement must not exceedspecified ratings and control units are always recommended to prevent damage in the event other anchoring in the system fails.
