Type MV-R Reverse Action and Type MV-T Tank Top Open Nozzles Medium Velocity
The Tyco Type MV-R Reverse Action and Type MV-T Tank Top Nozzles are open (non-automatic) spray nozzles designed for use in water spray fixed systems for fire protection of vessels or structures containing highly flammable liquids, gases and solids having flashpoints of 66°C (150°F) and below.
They are external deflector-type nozzles that discharge against the direction of the orifice in a uniformly filled spray pattern of medium velocity water droplets over a pre-determined area.
MV-R and MV-T nozzles are effective in covering exposed vertical, horizontal, curved, and irregular shaped surfaces in a cooling spray to prevent excessive absorption of heat from an external fire and possible structural damage or spread of fire to the protected equipment.
They also promote vapor dilution and dispersion.
The Type MV-R Reverse Action Nozzle, designed specifically to protect spherical vessels and bulk storage tanks, can be installed at any angle and discharges a 118° reverse angle conical spray pattern.
