The series LS pressure regulator, a direct-acting gas regulator, is widely used in both civil and industrial installations using Natural Gas, LPG and other noncorrosive gases.
Fail open：when the main diaphragm fails or the downstream pressure drops suddenly, the pressure regulator will be fully opened.
With balance valve：Equipped with a balance valve to eliminate the influence of inlet pressure change on outlet pressure.
With lever structure：The lever structure improves the closing pressure accuracy of the pressure regulator
Modularization: High reliability and keep in repair on line
With shut-off valve：Equipped with over-pressure shut-off valve
