System Description
This manual applies to the following Precision Valve & Automation, Inc. valves:
FCS300-F
FCS300-R
Front Closing Stainless Steel Spray Valve, Flat Cap
Front Closing Stainless Steel Spray Valve, Round Cp
FCS300-ES
Front Closing Stainless Steel Spray Valve, Extended Cap
FCS300-ES-ND
FCS300-ES-UF
Front Closing Stainless Steel Spray Valve, Narrow Cap
Front Closing Stainless Steel Spray Valve, Ultra Fine Cap
The valves above will be referred to as the FCS300 Series for the purpose of this manual.
Any information relevant to a specific valve will be indicated.
Theory of Operation
The FCS300 Series is a low pressure, low volume, front closing stainless steel spray valve
that uses air pressure to atomize fluids and transfer them to a substrate. This valve can be
used in a wide variety of coating applications applying low to high viscosity fluids. The
FCS300 Series has a divorced design comprising of two major sections. These include:
•Air section (red anodized portion)
•Fluid section (stainless steel portion)
Air Section
The air section is an aluminum body with a simple piston/cylinder combination used to
open and close the valve. A micrometer adjustment in the upper air body controls how far
the piston and needle assembly can retract thus regulating the rate of fluid flow. The
micrometer will display a distance that the piston and needle will travel.
Fluid Section
The fluid section is a stainless steel body, which includes a needle and seat combination
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, then stops as the needle moves back into the
seat. Atomizing air is applied when the needle is retracted to spray all fluid from the air cap.
The micrometer adjustment regulates the distance that the needle can retract out of the
seat thus controlling the orifice size and 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 FCS300 Series include: 303,
304 stainless steel, Teflon®, and Kalrez®.

Safety
Due to material contents being under pressure, eye protection is required for operators. All
spray valves should be used in a well-ventilated area. For additional precautions, refer to
the MSDS sheet for the dispensed material.
Setup
The FCS300 Series requires a 2-position, 4-way air solenoid valve to actuate the air
section. The valve should be operated with clean, dry air between 60-100psi. Two #10-32
threaded air ports are located on the air section of the valve. The port located furthest from
the midsection of the valve is air to close the valve. The port located closest to the mid-
section of the valve is air to open the valve. Quick connect air fittings are typically supplied
with the FCS300 Series to fit 5/32” tubing.
Note: The valve should normally be in the closed position.
Atomizing air is connected to the #10-32 threaded port located on the fluid section. Quick
connect air fittings are typically supplied to fit 5/32” tubing. Atomizing air should be
connected such that it turns on only when the valve is cycled to the open position. There
are two configurations that can be used to connect atomizing air. The first configuration
uses a Single Solenoid with a one output used to simultaneously open the valve and
pressurize the atomizing air regulator. The second option uses a Dual Solenoid
configuration to allow independent control of the atomizing air.
Fluid is supplied to the FCS300 Series through the 1/8”fnpt port located on the stainless
steel fluid section of the valve.
