- Wall-mount options for installation on room walls, vessel bulkheads or pipeline
- Orifice inserts, cores and strainers are easily removed for inspection or cleaning
- Most models can be supplied with an internal strainer
- Spray angles: 72° to 84°
- Uniform spray distribution from 3.5 to 20 gph (12.9 to 82 lph)
- Operating pressures from 30 to 1000 psi (2 to 80 bar)
Flow
The liquid passes through slots in the core component. The slots make the liquid spin in a circle at a very high speed. The energy from the spinning action causes the liquid to break up into very small droplets and form a hollow cone pattern as it exits the orifice.
