Coliter ® Electroplated Union Ball Valve – Lead-Free, PN16, Corrosion-Resistant Finish
QF2025 Electroplated Union Ball Valve – Lead-Free, PN16 with Corrosion-Resistant Finish
The Coliter® QF2025 Electroplated Union Ball Valve is a lead-free brass ball valve featuring a durable electroplated surface finish that enhances resistance to corrosion, oxidation, and environmental wear—ideal for humid, coastal, or high-visibility installations. Designed with a full-port configuration and a precision-machined chrome-plated ball paired with PTFE seats, it ensures smooth quarter-turn operation and bubble-tight shut-off with minimal pressure drop. The integrated union nut connection allows for quick disassembly and maintenance without disturbing the pipeline, making it highly serviceable in confined spaces. Rated at PN16 (1.6 MPa), it handles water, oil, and saturated steam within a working temperature range of -20°C to 100°C. Compliant with GB/T 17241 standards and available in sizes DN15–DN50 with ISO 228 (BSP) parallel threads, the QF2025 combines reliability, aesthetics, and ease of maintenance for residential, commercial, and export applications.
