Product Introduction

With its outstanding regulating performance, the electric V-type control valve is widely used in high-precision regulating applications across various industrial fields, including petrochemical, fine chemical, paper making, metallurgy, boiler feed water, and others.

The electric V-type control valve is extensively applied in industrial automatic control and shut-off for flow control, pressure control, temperature control, proportional control, and other regulation scenarios involving medium and low pressure as well as normal temperature media. It is equipped with manual operation function in case of power failure.

Features

It adopts an ultra-short flange distance structure, with the valve seat close to the end face flange, resulting in less material retention and superior sealing performance.
Compared with ordinary electric ball valves, its weight is greatly reduced to about 50% of that of ordinary electric ball valves. It features a compact structure and small volume.

The V-notch formed between the valve seat and the valve core can easily cut off various impurities in the pipeline, effectively ensuring unobstructed flow.

The valve core defines the valve characteristics. The unique V-shaped valve core structure resolves the control stability issues of traditional ball valves, enabling precise control of flow rate through the V-shaped opening of the spherical valve core.

The V-port angle is customizable to meet more precise flow shut-off characteristics and control functions.
