Introduction of low lift safety valve

1.In low lift safety valves, the disc only lifts a distance of ¹/_24th of the bore diameter. The discharge area is determined entirely by the position of the disc, and since the disc only lifts a small amount, the capacities tend to be much lower than those of full or high lift valves.

2.low lift safety valve valve opening height is between one twentieth to one fortieth times of the flow diameter.

A41H Spring Loaded Low Lift Safety Valves are use for the equipment and pipeline of the petroleum gas, air, water etc medium shat the working temperature are less than 300℃. A41Y-P/R type are used for the equipment and pipeline of the quality with corrode medium what the working temperature are less than 200℃. Take for extra pressure devices.
