Coliter ® Magnetic Lock Ball Valve – PN16, Lead-Free Brass
QF6002 Magnetic Lock Ball Valve – Tamper-Resistant Shut-Off for Utility & Residential Use
The Coliter® QF6002 Magnetic Lock Ball Valve is a lead-free brass ball valve featuring an integrated magnetic locking mechanism that prevents unauthorized operation. Designed for water, oil, and steam applications, it requires a proprietary magnetic key to open or close, making it ideal for water meter isolation, rental properties, public infrastructure, and shared facilities where tamper-proof control is essential. The valve has a full-port design with ISO 228 (BSP) parallel threads, rated at PN16 (1.6 MPa), and operates within a temperature range of -20°C to 100°C. Constructed from high-quality forged brass with a chrome-plated ball and PTFE seals, it ensures smooth quarter-turn operation and reliable bubble-tight shut-off. Compliant with WRAS, ACS, EN, and GB standards, the QF6002 combines security, durability, and certified safety for potable water systems.
