Features Applications Model Document

Body - High quality one piece casting which provides consistent uniformity. Sizes 2 inch to 6 inch are investment castings. Body is available in Wafer, Lug, Double Flanged, and Butt-welded.
Underneath Drawn Gland Packing - Allows for direct mounting of actuation and ease of adjustment.
Seat - An advanced design that provides a bidirectional interference and pressure assisted seal. This design achieves maximum seal at low, medium and high pressure.
Extended Neck - Allows for two inches of pipe insulation.
Packing - PTFE is a cup and cone system and Graphite is die formed rings for positive seals.
Bearings - Made of Graphite impregnated or Reinforced PTFE impregnated 316 Stainless Steel to ensure long service life.
Stem - Manufactured of high strength 17-4 ph Stainless Steel to provide maximum strength and stability for high torque applications.
Disc - Made of CF8M Stainless Steel and engineered to allow for quick release from the seat. This reduces the amount of torque needed to un-seat the disc.
Disc Taper Pins - Pins are offset from the center of the stem which places them in compression rather than in sheer. This gives them a yield point greater than the stem itself. Pins are welded in place after final assembly and testing.
Integrally Cast Disc Position Stop - Machined position stop on the body locates the disc in the seat to achieve maximum seat and seal life.
