LPG valves control liquefied petroleum gas at the cylinder and in the supply pipework. Because LPG is stored as a liquid under its own vapour pressure, cylinder valves typically include a spring-loaded relief function, and some designs add a fusible element that releases pressure if the cylinder is exposed to heat. This range lists spring working pressures such as 1.96 to 2.35 MPa or 375 psi depending on model, and fuse metal temperatures of 97.8°C to 105.7°C where fitted.
The table covers 20 Youngdo models. Cylinder valves in the YLC and LP series use W28-14th or W20-14th inlets with W22.5-14th-LH outlets at about 1.82 MPa, referencing KS B 6212 and KGS AA312. Models such as YLC-2821 and MT-2000 use 3/4-14 NGT inlets with a CGA 510 outlet at 250 psi to CGA V-1, and YBC valves use a quick-on outlet. OPD overfilling prevention devices, including OPD-3000 with a CGA 791 outlet, shut off filling before the cylinder is overfilled and reference UL 2227. YLG piping valves are rated 2.35 MPa with PT threads.
Certification varies by model across KGS, KS, CGA V-1 and UL.
