Butterfly Valves resist erosion and abrasion.

Press Release Summary:



Tufline high performance butterfly valves feature axially pliant seals. They include 2 components: outer segment of chemically inert, glass-reinforced PTFE; and deformation-resistant, memory-core membrane. Capable of handling virtually any material, these butterfly valves are available in soft-seated, fire-tested and high-temperature models. Pressure ratings include ANSI class 150, 300 and 600 in sizes up to 72 in.

Xomox's High Performance Butterfly Valves Feature Patented Axially Pliant Seal


CINCINNATI, Ohio, Dec. 14 - Xomox, a manufacturer of quarter-turn type process valves for over 45 years, provides its Tufline high performance butterfly valve with an axially pliant seal that extends service life.

The design is simple: There are no springs to break, no 0-rings to swell and no metal hoops to corrode; there is also no radial stretch. When the valve closes, the axial movement of the seat in the direction of the flow produces a pressure-assisted, leak-tight seal. As line pressure increases, the seal tightens.

Bi-directional flow and shutoff are easily accommodated; the same simple movement of the seat assures a reliable seal in either direction.

It includes two components - an outer segment of chemically inert, glass reinforced PTFE, and a deformation-resistant, memory-core membrane. Another important design feature: the HPBV's retainer ring eclipses the seal, thus protecting it from erosion and abrasion.

The Xomox Tufline high performance butterfly valves - capable of handling virtually any material - are available in soft-seated, fire-tested and high-temperature models. Pressure ratings include ANSI class 150, 300, and 600 in sizes up to 72
inches.
