Coliter®’s anti-theft ball valves are specialized shut-off valves designed to prevent unauthorized access, tampering, or bypass of utility meters in gas and water distribution systems. Featuring a fully enclosed handle or protective cap that requires a dedicated tool for operation, these valves ensure regulatory compliance and revenue protection for utilities. Constructed from high-quality forged brass with PTFE seals, they offer bubble-tight shut-off, quarter-turn operation, and durability under working pressures of 0.1–0.5 MPa (for gas) or PN16 (1.6 MPa) (for water), with operating temperatures from -20°C to +80°C. Commonly installed upstream/downstream of smart meters in residential and commercial buildings, the anti-theft design deters illegal connections while allowing authorized personnel quick access during emergencies or maintenance.
