General Features : 

• Provides easiest way of connection on large diameter pipes. Gives uniform circular surface sealing.
• No friction so no seal wear & hence longer life.
• No hinderance to flow so the pressure drop is minimum.
• Can be locked to prevent accidental opening.

Special Features of HPC Model : 

• All parts are machined out of drawn rods.
• Casting or Welding is not used. This increases the strength & capacity to withstand high pressures.
• Heat treatment & tempering gives high wear Resist where necessary.
