MVP Universal Proportioner
CHAPTER 1-Introduction and General Information

The Universal Proportioner as the description implies is available in a number of
configurations depending on materials used and customer requirements. In the event
the customer’s process and materials change, the system can be converted to handle
almost all thermoset resins and application with hardware and fluid section conversions.
Generally, this system is for two part Epoxy and Urethane resin systems for pour,
closed molding and spray applications.

(Note: To avoid confusion, manuals will only include assembly drawings and
rebuild instructions for the components included in unit purchase.)

Third component options are also available for low percentage down stream mixing of
additives which will require an additional bolt-on linkage drive package.

CHAPTER 2-Unit Information

Depending on the ratio’s and material outputs required, there are 3-fluid sections
available for the system. Each of the 3-fluid sections are also available made of
stainless steel construction with soft ball seats when vary low viscosity, corrosive
materials are used. One of the three stainless steel fluid sections are used which are
typically standard on the hardener side (adjustable linkage) when epoxy resins are
used.
The stainless steel fluid section soft seats use a Kalrez o-ring. Kalrez is a
perfluoroelastomer with exceptional chemical resistance to many acids and amines.
Only replace as needed, they are not include in the repair kits because of there cost.
Normal pump rebuilds do not require replacement of these o-rings. See fluid section
repair.

FLUID SECTIONS CUBIC INCHES PER CYCLE AT 4”STROKE:

UPLS-1000/1000-SS 24.72 C.I./Cycle
UPLS-4600/4600-SS 9.67 C.I./Cycle
UPLS-2400/2300-SS 4.82 C.I./Cycle

FLUID SECTION RATIO RANGE BY VOLUME:

If the same size fluid sections are used on both A & B materials the ratio range is from
1:1 to 3.10:1

The fluid section mounted onto the adjustable linkage has a range of 4” to 1.290” long
stroke of the piston rod.

With HV and 4600 fluid sections: 2.55:1 to 7.92:1 (10” air motor 17:1 power ratio)
With HV and 2300 fluid sections: 5.12:1 to 15.87:1 (7” air motor 10:1 power ratio)
With 4600 and 2300 fluid sections: 2.00:1 to 6:1 (7” air motor 19:1 power ratio)
With two 2400 fluid sections: 1:1 to 3.10:1 (5” air motor 15:1 power ratio)

(Note: The 2400 fluid sections are not balanced with the other fluid sections listed
above. No additional fluid section options are available with the 2400 section)

MAXIMUM FLUID PRESSURE (2,500 TO 2,700 PSI)

Depending on the size of the air motor, the air operating pressures and the size of the
fluid sections used dictates how high the fluid pressure can reach. Normally, these
pressures will never be met in normal operating ranges. However, if a material hose
had become plugged with set-up resin with the air motor at a high setting (100 psi or
higher) the plugged line could reach these pressures.
A pressure control valve (PLV-1000) is used to prevent pressures from exceeding the
maximum pressure point. Depending on the unit configuration, there may only be one
of these valves on the adjustable linkage pump and in some cases, on both pumps.
The pressure control valves are located on the hard plumbed fittings that exit the
material pump fluid sections. They have green 1/8” poly tubing attached at the top of
the valves which run back to a 3-way pneumatic (Mac valve) valve located off the side
of the air motor.

PRESSURE CONTROL VALVE

The pressure control valve has a spring loaded plunger, the plunger end is in the
material stream. If the material stream reaches pressures of 2,500 to 2,700 psi the
plunger is forced up. Once the plunger opens, it breaks an air circuit which in turn
closes the 3-way valve (Mac valve) that supplies air to the air-motor. When this
happens, air will bleed from the small holes on the side of the pressure control as long
as the gun is in the on position. Please see the PLV-1000 manual for more information.

(NOTE: The pressure control valve does not release fluid pressure. It only shuts
off the air supply to the air motor).

AIR MOTORS (POWER HEADS)

Available Diameters and SCFM air consumption at 40 cycles/min.

60 psi 80 psi

10” Diameter: 72 SCFM 90 SCFM
7” Diameter: 37 SCFM 46 SCFM
5” Diameter: 20 SCFM 25 SCFM
Incoming supply air pressure, regardless of the Air Motor size and operating pressure

can not be any lower then 90 psi. , when running the system. This is critical for the Air
motor pilot valves which affect the air motor change of direction. Use no smaller then
½” diameter hose supply line to unit of clean dry air with no quick disconnects. A ¾”
diameter air hose or larger is recommended when using the 10” air motor at higher
rates.

Customer is responsible for air supply connections with properly sized air hose and
compressed air volume (SCFM) available to system.
