Product Overview

The Electric Welded Ball Valve is an advanced, automated pipeline fluid control solution engineered for industries demanding zero-leakage, high structural integrity, and exceptional reliability. By combining a premium stainless steel (SS304/SS316L) fully-welded or butt-welded valve body with a versatile, heavy-duty intelligent electric actuator, this valve eliminates the risk of joint leakage common with flanged connections. Built to withstand pipeline pressures up to 1.6 MPa and operating seamlessly in harsh environments, it offers precise remote modulation or quick on-off isolation for a vast array of fluid process media.
