Product Overview
Description of the Dymax Spray Valves
The Dymax Model 110 and 210 Spray Valves are low pressure, low volume, front-closing
stainless steel valves. These valves use air pressure to atomize fluids and transfer them
to a substrate. The valves can be used in a wide variety of coating applications, applying
any number of low-to-high viscosity fluids.
The Model 110 is a standard-flow spray valve and should be used with materials that
have a viscosity less than 10,000 cP.
The Model 210 is a high-flow spray valve and should be used with materials that have a
viscosity greater than 10,000 cP.
Component Overview
The valve is comprised of two major sections, the air section (red anodized portion) and
the fluid section (stainless steel portion). The air section of the valve is constructed of
an aluminum body. It contains a simple piston/cylinder combination used to open and
close the valve. This section also houses the stroke-adjustment bolt, which is located in
the upper air body. The stroke-adjustment bolt controls how far the piston and needle
assembly can retract thus regulating the rate of fluid flow.
The second section of the valve, the fluid section, is constructed of stainless steel. It
contains a needle and seat combination, which is located at the end of the Valve inside
the atomizing air cap. Fluid flows through the seat orifice as the needle retracts out of
the seat. The fluid stops as the needle moves back into the Seat. When the needle is
retracted, atomizing air is applied to spray all of the fluid from the air cap. The stroke
adjustment bolt located on the air section of the valve regulates the distance that the
needle can retract out of the seat. This controls the orifice size and the rate of fluid flow.
A precision air regulator is used to control a precise amount of atomizing air. Fluids can
include but are not limited to solvents, conformal coatings, grease, etc.
Wetted parts on the spray valve include: 303, 304 stainless steel, Teflon®, and Kalrez®

System Interconnect
Air
The valve is a normally-closed spray valve. It requires a 2-position, 4-way air solenoid
valve to actuate the air section. The valve should be operated with clean, dry air
between 60-100 psi. Two #10-32 threaded air ports are located on the air section of the
valve. The air port located furthest from the midsection of the valve is the air line to
close the valve. The air port located closest to the mid-section of the valve is the air line
to open the valve. Quick-connect air fittings are typically supplied with the spray valve
to fit 5/32" tubing.
Atomizing air is connected to the valve through the #10-32 threaded port located on the
fluid section (D). The atomizing air should be connected so that it turns on only when
the valve is cycled to the open position. There are two configurations that can be used
to connect the atomizing air.
The first configuration uses a single solenoid with one output. This configuration can be
seen in Figure 2. The single solenoid in this configuration is used to simultaneously open
the valve and pressurize the atomizing air regulator.
The second configuration, which can be seen in Figure 3, uses a dual solenoid to allow
independent control of the atomizing air.
Fluid
The spray valve requires a material reservoir or pressure tank to draw material from.
The material reservoir should be connected to the valve via the 3/8" OD push-to-
connect fitting already installed on the stainless steel fluid section (D) of the valve.

Operating the Dispensing Valve
Setup and Operation
Refer to Figure 1 for part reference designation.
1. Plumb the valve as outlined in the set-up procedures.
2. Regulate the air pressure operating the valve between 60-100 psi.
3. Making sure that the valve is not aimed toward anyone, cycle the valve several
times. When the valve is cycling, the Piston (K) can be heard hitting the Stroke
Adjuster (O), and the Needle (C) can be seen going up and down in the center.
4. Adjust the atomizing Air Pressure Regulator between 1-2 psi. Air should be felt
flowing from the end of the valve when the valve cycles open.
NOTE: If the valve is not cycling properly, refer to the Troubleshooting Section of
this manual.
5. When the Fluid Delivery System is connected to the valve, pressurize the material
to be dispensed.
6. Once again, cycle the valve open to purge. Fluid should begin to spray from the tip
of the Air Cap (A).
7. Continue cycling the valve until all air is removed from the Fluid Line and a steady
spray pattern of material can be seen.
8. Adjust the atomizing air pressure to achieve proper spray of material. This pressure
will vary due to the viscosity of the fluid.
9. Check the Fluid Connection and Packing Nut (F) for leaks. If the valve is leaking,
refer to the Troubleshooting Section of this manual.
10. Turn the Stroke Adjuster (O) until the desired flow rate is achieved. Turning the
Stroke Adjuster (O) clockwise will decrease the material flow rate and counter-
clockwise will increase the material flow rate. If the Stroke Adjuster (O) is turned
all the way down, it will stop fluid flow entirely.
11. Once the stroke adjustment setting is determined, use an adjustable wrench to
tighten the Lock Nut (N) up against the Upper Air Body (M).
NOTE: Refer to the Troubleshooting Section for any problems.
