Pressure Reducing Landing Valves

Pressure Reducing Valve has been designed to meet the needs of modern fire protection technology. It enables a uniform fire fighting pressure to be maintained at any hydrant in a fire protection system irrespective of its location. Efficient pressure control is not affected by differences in inlet pressure which may occur at varying flow levels.

Expensive relief piping systems are completely eliminated, thus dramatically reducing installation costs. The regulator can be quickly and easily adjusted in-site to meet individual floor level pressure requirements.
