BX2001 Valves Large diameter, one-piece high strength shaft reduces deflection for positive, repeatable shut-off at higher ∆P than similar valves. Flats or “double D” on shaft provide positive indication of valve position and simplified adaption to automatic actuation. Independent packing set adjustment prevents stem seal emissions. Blow-out proof stem design complies with API 609 criteria to guard against catastrophic leakage and stem blow-out in the event of shaft failure. Positioning holes on wafer body allow easy installation and proper alignment between flanges. Wide choice of packing...

Unique, high strength Gibb pin positively locks valve shaft to the disc. Gibb pin is used on 2 in (50 mm) through 12 in (300 mm) sizes. Severe Service Bearings The special PTFE resin is pressure molded onto a perforated 316 SS sheet. The perforations lock the PTFE onto the 316 SS making a unified bearing that exhibits high corrosion resistance with unparalleled cycle life. This process results in a PTFE/SS bearing where high radial and lateral loads will not deform the PTFE and strip it from its stainless steel backing. Particularly suited for environments detrimental to glass fibers or...
