Metal Bellows, Expansion Joint & Flexible Joint

Metal bellows, expansion joints, flexible joints, and metal flexible hoses are flexible connectors used to reduce a pipe's thermal expansion, cold extraction, movement, and vibration.  317 Valve’s flexible connector products are made from stainless steel, and they are suitable for compensating for the displacement of general piping during thermal expansion or contraction.

According to the type of movement in the pipeline, connectors, and working pressure, we provide several series of expansion joints:According to the type of movement in the pipeline, connectors, and working pressure, we provide several series of braided expansion joints and flexible metal bellows:

• Axial Movement: JF150 series, JF250 series, JF400 series, JF1000 series,
  JF500HE series
• Lateral Movement: JF800 series
• Axial and Lateral Movement: JF850 series
