Purpose‑built for tank‑level control within the PTA (Purified Terephthalic Acid) chemical industry, the Masoneilan 75000‑Series control valve delivers outstanding resistance against erosion and flashing when handling corrosive or viscous process fluids.
Its full‑ported sweep‑angle body incorporates a smoothly contoured internal gallery, cutting down pressure loss across the valve body and reducing particle‑induced erosion caused by direct flow impingement.
Driven by a high‑force actuator, the integrated one‑piece plug‑stem assembly features reinforced surfaces and guiding fins capable of shearing hardened crystalline material deposited inside storage tanks, while providing stable throttling for solid‑laden media.
Combined heavy‑duty top stem guidance and full‑stroke‑length port‑guided plug flutes greatly dampen trim vibration and mitigate component fatigue, enabling the valve to achieve extended operational lifespans under harsh severe‑service conditions.
Multiple sweep‑angle body options‑‑90°, 120° and 135°‑‑provide greater piping flexibility and simplify installation in restricted, space‑constrained tank‑mounted layouts.
