Product introduction

The working principle of EV Series electric regulative valve is simple and reliable. The complete electronic is unnecessary to match with servo amplifier, it is easy to controll the operation through direct input control signals and single-phase power supply, and can achiveve the regulation of pressure, flow, temperature, liquid level and other process parameters.
★ DN15-200
★ V-shaped notch core is suitable for scouring or viscous fluids, pulp or other containing mixed solid, or fibrous slurry flows.
★ The core still contacts with the sealing surface when the core is rotating. With the ball off, it produces a sheared effect, to make particle adhesion minimum.
★ Large flow capacity, straight-through constructure makes a small pressure drop.
★ regulative precision is high, adjustable ratio is large, the maximum is up to (300:1)
★ good sealing performance( double spherical sealing)
★ allowable pressure differential is large
Excellent regulative performance, makes the product widely used in various industrial fields of high-precision regulative links.
