Gas valves come in many shapes and sizes, with different functions and roles in a gas system. Common to them all is that they allow you to control the flow, pressure and direction of liquid and\/or vapour.<\/p>

We do our best to keep up with the ever expanding and innovative market of gas valves for LPG. The selection spans over mechanical, digital and electromechanical gas valves to suit all LPG related purposes and applications. Whether it is pressure control, bypassing, shut-off, excess flow check, pressure relief or multi valves that is needed, this is the place to find them.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

One-way valves that prevent the contents of a container from escaping if the piping or fittings unexpectedly break. Back check valves close off if the direction of flow changes, or if flow stops.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

A threaded excess flow valve is a bi-directional valve that shuts off flow in one direction if it exceeds a predetermined value. Its bleed-off feature assists in pressure equalisation.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
