FEATURES

Disc

• Streamlined design offers higher Cv and lower pressure drop.
• Machined Double D drive ensures close tolerances thereby elimating the imprecision commonly found in the cast-in drives offered by our competitors.

Shaft

• Triple shaft seals support the primary seal on machined radius of the disc. Our triple shaft seals ensure a dry stem design.
• Two secondary shaft seals are located inside the seat shaft holes and an environmental shaft seal eliminates contaminates from entering the shaft bore.
• Two self lubricated bronze bearings offer consistent torque value and eliminate side loading.

Disc/Shaft Connection

• A high strength machined Double D drive ensures a positive shaft to disc connection.
  
• Disc floats inside the seat for positive sealing and extended seat life.
  
• No pins or bolts are exposed to flow.
  
• Offset shaft retainers mechanically retain the shaft in the body ensuring a blow out proof design.
