Reglamento Técnico Salvadoreño RTS 23.02.02:21 RECIPIENTES A PRESIÓN. CILINDROS PORTÁTILES PARA CONTENER GLP. VÁLVULA DE ACOPLAMIENTO RÁPIDO ("QUICK COUPLING") CON VOLANTE PARA CIERRE MANUAL. ESPECIFICACIONES (Salvadoran Technical Regulation RTS 23.02.02:21, Pressure vessels. Portable LPG cylinders. Quick coupling valves with a handwheel for manual closure. Specifications) (22 pages, in Spanish)
The notified Regulation lays down the minimum specifications and test methods for non-POL type quick coupling valves with a handwheel for manual closure, used for the filling and release of liquefied petroleum gas (LPG) for domestic use stored in portable containers circulating in El Salvador. As an integral part of the valve, the valve's ability to be closed manually ensures increased safety since, in the case of an LPG leak in the domestic system, the valve may be closed and the leak stopped simply by operating the handwheel.
