Product Introduction

Electric V-type control valve for precise modulation in high-accuracy control. Applied across petrochemical, fine chemical, pulp & paper, metallurgy, and boiler feedwater service. Performs flow, pressure, temperature, and proportional control in industrial automation and on/off shutoff, for low- to medium-pressure, ambient-temperature media. Includes a manual override for operation on power failure.

Features

Ultra-short face-to-face design — Seat sits close to the flange face for minimal cavity volume and bubble-tight shutoff.

About 50% lighter than standard electric ball valves, with a compact, space-saving body.

The V-notch between seat and ball shears entrained solids to keep the line clear and prevent clogging.

The V-ball sets the flow characteristic; its configurable V-port angle enables precise flow control and tailored shutoff, removing the instability of conventional ball valves.
