Two-piece Flanged Ball Valve — Precision Control for Industrial Applications
Image failed to load
Industry Overview
The JVL two-piece flanged ball valve is engineered for demanding industrial environments requiring reliable shut-off and precise flow control. Unlike traditional valves, the two-piece design minimizes friction during operation, reducing seal wear and lowering the torque required to operate the valve. This feature enables compatibility with smaller actuators while maintaining precise control.
Widely adopted across petrochemical, chemical, municipal water supply, wastewater, and industrial automation sectors, this valve ensures operational reliability in both routine and critical applications.
Technical Specifications
The valve is designed to operate at nominal pressures of PN 1.6 to 2.5 MPa and withstand strength test pressures up to 3.8 MPa. Low-pressure gas seal tests are conducted at 0.6 MPa to ensure leak-free performance. It is suitable for a wide range of media, including water, oil, gas (Q41F-(16-25)C), nitric acid (Q41F-(16-25)P), and acetic acid (Q41F-(16-25)R) . Operational temperature ranges from -20°C to 180°C, making it adaptable to varied industrial conditions.
