Exploded View of Electric V Type Control Valve

Product Introduction

The explosionproof electric V-type regulating valve delivers accurate modulating performance for demanding control duties across petrochemical, fine chemical, pulp & paper, metallurgy, and boiler feedwater systems.

Suited to automatic on/off and modulating control of flow, pressure, temperature, and proportional control on medium- to low-pressure, ambient-temperature media. A manual override is provided for operation during power loss.

Features

  • Lightweight — Integrated body with an ultra-short face-to-face length cuts weight to ~50% of a comparable standard ball valve.
  • Self-cleaning shear — The seat-to-ball shearing edge clears solids and impurities from the line, keeping flow unobstructed.
  • Stable modulation — The V-type ball eliminates the instability of conventional ball valves. Equal-percentage characteristic gives a linear relation between the controlled variable and valve travel; flow builds progressively from opening.
  • Flexible trim — The ball sets the flow characteristic; different port shapes let one nominal size cover multiple Cv values and characteristics.
  • Tight shutoff — Dual spherical sealing improves sealing and limits leakage, rated to FCI 70-2 Class IV.
