Product Overview

Model MCV-150 uses a dual-seal bellows-and-packing bonnet to isolate process fluid from the stem packing path. Single-seat and pressure-balanced cage-guided variants are available for toxic, highly corrosive, radioactive, rare, or valuable media.

Product Features

  • Metal bellows provides the primary stem seal.
  • Secondary packing adds a second containment barrier.
  • Single-seat or pressure-balanced cage-guided trim can be selected.
  • Construction targets zero process leakage through the stem-packing clearance.
  • Pneumatic or electric actuator packages are available.
