SPRAY VALVE (Ball Valve)

The Guardian 55 ES unlike its larger stable mates in the Guardian

line, does not utilize an insecticide pump to meter a chemical

formulation to the atomization nozzle but rather pulls or draws a

siphon from this specially designed nozzle. The nickel plated brass

ball valve is equipped with Viton® elastomeric seals and a stainless

steel ball for trouble free operation. The manual ball valve is a 2-

position (open/close) valve that when closed blocks the flow path

from the formulation tank to the atomization nozzle.

When

opened, the strong vacuum effect from the siphoning nozzle pulls

liquid into the nozzle for atomization.

A remote spray on/off option is available for the Guardian 55 ES in

the form of a 12-volt electric solenoid valve which is installed in

place of the manual valve. Power to support this remote spray

on/off option is drawn from a 12-volt source such as an accessory

port or "cigarette lighter" port found on many utility vehicles. A

length of cable is supplied to the valve allowing a driver to activate

spray without having to physically be at the machine and place the

ball valve in the closed position. If this option is of interest to you,

contact your dealer, distributor or sales associate to find out more.

The chemical or formulation is drawn through this fitting to the

nozzle. Inside this fitting resides both an inline screen filter as

well as an orifice disk. The purpose of the orifice disk to limit the

amount of flow to the nozzle based on the product label and

desired droplet size. Refer to the table provided in this manual to

select the appropriate orifice disk for desired product and

atomization performance.

2.5 U.S. gallons (9.46 liters) is the capacity of the formulation tank

installed on this ULV sprayer.

The opaque high density

polyethylene (HDPE) tank is suitable for all known products used

in Vector control. Additionally, the formulation tank is supplied
