Product Overview
Newway Electric V-Type Hard Seal Ball Valve: Wear-Resistant Solution for Particle Media Control
I. Technical Overview
Newway electric V-type hard seal ball valve is specially designed for abrasive media like slurry, particles, and coal ash, covering DN15~DN200 (1/2″~8″). Made of WCB cast steel or 304/316 stainless steel, with PN16 (1.6MPa) pressure rating and -20℃~140℃ (-4℉~284℉) operating temperature (up to 280℃ for high-temperature models). The hard seal structure of V-shape ball core and metal seat forms a shearing effect, effectively cutting fibers and particles to prevent jamming, suitable for abrasive fluid control in power, metallurgy, chemical, and mining industries. The electric drive supports 220VAC power input with intelligent positioner for precise 0~90° regulation and emergency shut-off.
II. Core Product Features
(A) V-Shape Hard Seal Shearing Structure
Wear-Resistant Shearing Design: V-shape cut core with Stellite overlay (HRC60~65) on 304 stainless steel forms a metal hard seal with 2Cr13 nitrided seat, shearing fibers up to 2mm diameter, ideal for slurry and coal ash water;
Precision Flow Regulation: Equal percentage flow characteristic with 50:1 regulation ratio, enabling linear control within 0~90° rotation, 25% higher accuracy than standard ball valves;
Low Flow Resistance: Smooth flow path when fully open, resistance coefficient ≤0.9, 35% less pressure loss than globe valves, saving ~8,000kWh annual pumping energy.
