ABZolute Seal Series 400 Double
Offset and Triple Offset High Performance
Butterfly Valve by ABZ

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.

Mounting Flange

Designed to direct mount actuation for ease of installation and cost savings. No bracket is needed for manual actuation or for automatic automation up to 18 inch.

Underneath Drawn Gland Packing

Allows for direct mounting of actuation and ease of user adjustment of the gland nuts while method of operation is attached. A rocker design is incorporated to compensate for uneven adjustment of the gland nuts.

Seat

An advanced design that provides a bi-directional 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 strenghth and stability for high torque applications.

Disc

Made of 316 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 poing 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.
