Size Range : 1/2″ to 4″ Screwed / Flanged
Function
Safety valves are used on Pressure equipments, Containers or Pipeline as over Pressure in the equipment increases and exceeds allowance, the valve can automatically open to discharge some mediums to prevent the pressure keeping raised. When the pressure decreases till to the stipulated value, the valve can close in time to avoid the pressure too much reduced, so that normal production will be carried out.
