Proco ProFlex - Model Style 234-L -Rubber Expansion Joints

Some of the notable features and benefits of the Proco Series 234L are:

• Absorption of Directional Movement
• Absorption of Vibration, Noise and Shock
• Compensation for Misalignment
• Wide Range of Service and Lighter Weight
• Easy Material Identification

Proco Style FA234-L Rubber Expansion Joints are designed for piping systems carrying heavy solids that experience large lateral offsets due to settlement. The Style FA234-L is a low profile quadruple filled arch design with a built-in reinforcing ring at the top of the arch to provide extra stability for lateral movements up to 4”.

Absorbs Directional Movement

Thermal movements appear in any rigid pipe system due to temperature changes. The Style 233-L and 234-L low profile arch allows for axial compression or axial extension, lateral deflection as well as angular and torsional movements. (Note: Rated movements in this publication are based on one plane movements. Multiple movement conditions are based on a multiple movement calculation. Contact Proco for information when designing multiple pipe movements.)

Absorbs Vibration, Noise and Shock

The Style 233-L and 234-L expansion joints are manufactured with the integral rubber flange joining the body at a true 90º angle. This ensures the product will install snug against the mating pipe flange free of voids creating less turbulence in the pipe system.

Compensates for Misalignment

The Style 233-L and 234-L expansion joints are designed for large lateral movements due to long term settlement.

Wide Service Range and Less Weight

Engineered to operate up to 145 PSIG (nominal size dependent) or up to 250ºF (elastomer dependent), the Series 233-L and 234-L can be specified for a wide range of piping system requirements. The Series 233-L and 234-L rubber expansion joints are constructed in various elastomers with rubber impregnated polyester tire cord and a reinforcing ring at the top of the arch to provide stability in large lateral offset conditions.

Material Identification

All 233-L and 234-L expansion joints are strip branded with cure dates and elastomer designations.
