Coliter® provides a specialized range of brass valves with integrated locking mechanisms to prevent unauthorized operation in residential, municipal, and utility applications. The series includes magnetically locked ball valves (e.g., QF6002, QF6213, QF6313) requiring a proprietary magnetic key, mechanically locked models (e.g., QF6327) with slide or pin locks, and multi-lock variants (QF6223) for enhanced security. Many feature built-in Y-strainers or thermometers for added functionality. All are made from lead-free brass, comply with WRAS, ACS, EN, and GB standards, and operate up to PN16 (1.6 MPa) and 100–120°C. Ideal for water meter isolation, rental properties, and public infrastructure—combining tamper-proof control with certified safety for potable water systems.
