    2.0 Quantity As required
    3.1 Type Non clogging
    3.2 Nozzle K Factor K- [20, 22, 25, 30, 35, 41, 51, 64 & 79]
    3.3 Nozzle Spray Angle 120o + 3o, 100o + 3o
    4.0 Application Fire Water Service
    5.1 Working Pressure 1.4 to 3.5 Kg/sq.cm
    5.2 Hydro Test Pressure 15 Kg/sq.cm
    6.0 Working Principle Foreign/solid free clear water at rated pressure enters nozzle and passes through nozzle chamber to impinge on deflector. The impingement breaks the water jet into macro particles and produces pre-designed angle of conical spray at medium velocity; the deflectors determine the pre‑designed angle. The flow at specified pressure is determined by the K-factor of the design, which is pre-designed.

    5.1 Working Pressure 3.5 to 5.5 Kg/sq.cm
    5.2 Hydro Test Pressure 15 Kg/sq.cm
    6.0 Working Principle WATER AT SCHEDULED PRESSURE ENTERS NOZZLES THROUGH INTEGRAL STRAINER AND FOREIGN SOLIDS ARE STRAINED.
    THIS CLEAR WATER NOW PASSESS THROUGH SPIRACLE WITH ONE CENTRAL ORIFICE AND/OR THREE PERIPHERAL VEINS INTO VORTEX CHAMBER.
    THE VANES INDUCE VORTEX BY PROVIDING RIFLING MOTION TO WATER INSIDE THE WATER THROUGH THE CENTRAL ORIFICE IMPINGES ON THIS RIFLING WATER AND BREAKS THE VORTEX.
    THIS ACTION CAUSES THE WATER TO BREAK INTO MICRO PARTICLE AND COME OUT THROUGH THE NOZZLE UNDER VELOCITY HEAD AT PREDESIGNED ANGLE OF CONICAL SPRAY AT HIGH VELOCITY.
