Coliter®’s gas ball valves are engineered for reliable, leak-tight shut-off in natural gas and LPG piping systems. The series includes standard models like QF3128 and QF3122, as well as lockable variants (QF5121A, QF5122) with integrated padlock or key-lock mechanisms to prevent unauthorized operation—ideal for utility, residential, and commercial gas lines. All valves feature high-quality forged brass bodies, PTFE seals for long-term tightness, full-port design for unrestricted flow, and compliance with national gas valve standards. Rated for working pressures of 0.1–0.5 MPa and temperatures from -20°C to +60°C, they ensure safe, durable performance with quarter-turn operation and clear open/close indicators.
