Flanged Turbine Wafer Butterfly Valve for Biotechnology Facilities

Product Overview

The phone call comes in mid-morning. A biotech contractor, behind on a shutdown window between running process halls, wants to know when the wafer valves land. Between two existing flanges there is almost no face-to-face to spare, and the installer has maybe a day before the line goes hot again.

On the assembly floor the bodies are cast, the gear operator bolted on, and the disc set single-eccentric. Soft seat for clean water, metal seat for hotter media, chosen by the line. Pressure class sits at Pn10 or Pn16, and the plate range runs -30 C up to 400 C. Every unit bench-tested for seat tightness before the clean wrap.

Five pieces opens the run; the FOB range climbs from US $11 to $880 once size and seat are picked.

Key Features

A long lever between stainless pipe racks asks for a bruised wrist, so the biotech crew takes the gearbox drive and turns the same quarter-turn two-handed.

Nameplates are stainless and riveted, never stickered - a steam-cleaned hall peels a paper label inside a month. The gearbox oil level is checked before crating, so the first open-and-close cycle on site runs quiet.
