Spray Headers

Spray Header Construction

For operations using raw water or water-based coolants, USC provides stainless steel valve assemblies and stainless steel headers.  While oil-based coolants use valve assemblies made of stainless steel and aluminum with a carbon steel header.

System Components
The USC spray headers feature independent chambers for coolant supply, electrical connections and, in water-based systems, a pilot air chamber. All headers are customized for each system.

The cut-away shown to the right illustrates the two chambers of a oil-based header and how the USC Spray Valves may be installed and serviced from the nozzle side of the system.

Nozzle plates are fed from the valve assemblies which contain the valve and the electrical connection for control. One, two or three valves can be mounted on each spray zone.

All O-rings and fasteners on the valve assembly are designed to ensure proper sealing and prevent loss of components during installation and removal. Plus, valve assemblies and nozzle plates are easily installed and removed with just pliers and hex wrenches. There are no loose parts in the valve assemblies and nozzle plates.

The nozzle plates direct the fluid from the valve assembly to the nozzle. VeeJet® nozzles are placed to optimize performance using the USC SPA (Spray Pattern Analysis) modeling software program.

United States Controls' patented self-cleaning valve design

This detailed animation shows the advantage of USC's spray valve assemblies. These spray valves set the standard for accuracy, longevity and reliability in the aluminum and steel industry. USC valves can be pulsed on and off up to 5 cycles per second and are offered as single, double or triple row assemblies to spray the exact amount of coolant required on each zone. Each valve may be controlled independently of the others.
