7-Flex PFV

• PFV Polymer
– Cushions strands, reducing wire-contact stress
– Keeps lubricant in, allowing internal movement between wires and strands
– Reduces internal abrasion due to debris    
– Provides greater wear area for greater resistance to bending fatigue

• 7-strand construction

7-Flex PFV

Combining the advantages of PFV, a high-grade thermoplastic material, extruded into a 7-Flex lubricated wire rope, provides additional advantages over non PFV ropes.

Through our process, the finished rope has the strand valleys between strands and interstices equally filled with plastic, which seals the lubricant and assures a balanced rope when finished.  This also has proven in many applications to give you longer service life and cleaner operation than conventional wire ropes.

On the inside, you’ll find our 7-Flex wire rope that withstands the tough pressures of your demanding jobs while the PFV cushions the strands, distributes internal stresses, keeps in wire rope lubricant and keeps out dirt and debris.  PFV also helps shed water and dirt, giving you a clean, smooth surface to make it easy to pass over sheaves and onto drums. This smooth surface works to clean and polish as it extends the service life of your sheaves and drums, while also reducing your cleanup requirements and your maintenance costs.

PFV doesn’t melt or soften from the heat of normal operating temperatures. It’s also virtually unaffected by sunlight and cold weather. The result is longer service life from your wire rope.  It’s a Union wire rope, Tested, Tough & True.
