The Camflex II rotary globe valve (photo) can help users meet environmental emissions standards. Featuring a specially developed Emissions Free (EF) Seal and many other innovative design characteristics, the Camflex II valve reduces equipment emissions that can occur at the valve shaft sealing or packing, particularly after long-term operation. The EF combines a double O-ring sealed packing follower with low-friction tetrafluoroethylene- (TFE) based packing materials for long-term service that complies with low-emissions standards. In addition, the small-range rotary motion of the Camflex II valve shaft provides benefits, such as preventing contaminants from entering the packing system from atmospheric exposure, which can accelerate corrosion. Another feature of the Camflex II valve is an integrated extension bonnet that enables the standard TFE packing material to withstand its full temperature range — up to 400°C. — Dresser Masoneilan, Courbevoie, France
