System Description
This manual applies to the following Precision Valve & Automation Inc. valve:
PC150
Two-Component Dispensing Valve
Theory of Operation
The PC150 is a rear-closing, two component valve designed to dispense two component
materials. This valve has an adjustable snuff back to prevent drips or strings at the end of
the static mixer. Part A and Part B materials separately flow in and out of the valve into a
disposable static mixer. It is not necessary to disassemble and clean the valve at the end of
each day. The PC150 has a divorced design made of two major sections: the air section and
the fluid section.
Air Section
The air section is an aluminum body with a simple
piston/cylinder combination used to open and close
the valve. The stroke adjustment screw in the upper air
body controls how far the piston and rod assembly can
retract as well as the snuff back.
Fluid Section
The fluid section is made of stainless steel and all seals
are FFKM. The fluid section includes two rods with
seals on each side of the valve to control fluid flow of
Part A and Part B. Fluid dispenses as the rods move
past the seals to the forward position. When the rods
retract back into the seals, the fluid flow stops and
creates a snuff back action on the fluid.
