In a kraft pulp mill, the chemical recovery area poses significant valve challenges. Corrosion, abrasion, scaling, and dewatered solids all combine to create formidable valve challenges. Recovery applications can range from high concentrations of solids in black liquor evaporators, to precipitated calcium scale in green and white liquor, to tall oil and other fatty or resinous acid byproducts from soft woods. Engineered Valves offers products that are up to the challenges of tough recovery applications.

Cam-Tite Hastelloy C

Applications: tall oil, other applications involving fatty or resinous acids from soft wood

Featuring a tough-duty, corrsion resistant Hastelloy body, the Cam-Tite features an extended bonnet for higher temperature service. This raises the stem seat further from the flowing fluid, reducing the effects of temperature extremes.

• Stem support minimizes galling and stem leakage
• Corrosion resistant ceramic ball is impervious to gases
