D4a Protectospray Directional Spray Nozzles
P000126 -
D4a Protectospray Directional Spray Nozzles are open (non-automatic) directional spray nozzles and they are designed for use in water spray fixed systems for fire protection applications. They are external deflector-type nozzles that discharge a uniformly filled cone of medium velocity water droplets. The Type D4a Nozzles feature a four arm body design that helps assist against mechanical or physical damage similar to a sprinkler guard used on automatic sprinklers.

- Approvals:
+ The TYCO Type D4a PROTECTOSPRAY Nozzles meet the requirements of MIL-S-901C for lightweight Grade A shock proof equipment.
+ The bronze Type D4a PROTECTOSPRAY Nozzles with a natural finish and with 80 to 160 degree spray angles meet the requirements of MIL-H-19387A, Type I.
- Maximum Working Pressure :175 psi (12.1 bar)
- Discharge Coefficient: learn more in the datasheet
- Spray Angles: learn more in the datasheet
- Thread Connection: 1/2 inch NPT (DN15)
- D4a 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. In some applications, depending on water design density requirements, the Type D4a Nozzles may also be used for fire control or extinguishment.
- Corrosion resistant coatings, where applicable, are utilized to extend the life of copper alloy sprinklers beyond that which would otherwise be obtained when exposed to corrosive atmospheres.
