Steam Boiler Relief Valve

Steam Boiler Relief Valves are used on pressure equipments,containers or pipilines as overpressure protection. When the pressure in the aquipment increases and exceeds allowance, the valve can automatically open to discharge some mediums to prevent the pressure keeping raised.

Series - 150 To 900

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 be carried out.
