Parker Pneumatic V-575P User manual

INSTALLATION/OPERATING INSTRUCTIONS
A Flow Control "Sandwich" controls the flow of air from the valve exhaust
ports to atmosphere. The Sprint valve (4-way) is typically used with a
double acting cylinder alternately pressurizing one end while exhausting
the other. Cylinder speed can be influenced by restricting the exhaust
path.
NOTE: If the complete blockage of air to atmosphere or extremely fine
adjustments are required DO NOT use a Flow Control "Sandwich".
Instead connect Micrometer Flow Control Valves to cylinder ports of
subbase or manifold with the free flow direction pointing away from the
subbase or manifold.
Flow Control "Sandwich" is intended for use with subbase or manifold
mounted Sprint Valves. It is only recommended for use with Common
Port versions of Sandwich Regulators. The Flow Control is to be
assembled between the regulator and the subbase or manifold using the
(3) 1/4-20 X 1-1/4" low head cap screws provided in the kit. If used with
Single Port or Independent Port versions of Sandwich Regulators
functionality is limited as follows:
Flow Control "Sandwich" used in conjunction with Single Port
version of Sandwich Regulator - Adjust speed with the adjusting
screw on the regulator end of the Sandwich Regulator. It adjusts the
speed of exhaust flow from cylinder ports "2" and "4". Independent
speed adjustment is not possible. This could result in different
exhaust speeds for cylinder ports "2" and "4" since line pressure is
supplied to one cylinder port and a regulated pressure is supplied to
the other. The other adjusting screw is non-functional.
Flow Control "Sandwich" used in conjunction with Independent
Port version of Sandwich Regulator - Fully close one adjustment
screw and perform adjustment with the other. Either adjustment
screw controls the speed of exhaust flow from cylinder ports "2" and
"4". Independent speed adjustment is not possible. This could result
in different exhaust speeds for cylinder ports "2" and "4" since a
different regulated pressure is supplied to each cylinder port.
APPLICATION LIMITS
These products are intended for use in general purpose compressed air
systems only.
Operating Pressure Range: PSIG Bar kPa
Minimum 35 2.4 241
Maximum 150 10.4 1034
Operating Temperature Range: 20°F (-7°C) to 140°F (60°C)
Voltage Range: +10% to -15% of Valve Rating
(Applicable only for solenoid operated valves)
NOTE: The above ratings are those of the associated valve.
INSTALLATION
1) Remove the valve from the subbase or manifold (if assembled) by
removing and discarding the three mounting screws.
2) Clean all mating surfaces of valve, subbase or manifold and Flow
Control "Sandwich" of dust and dirt.
3) Apply a light coating of grease (in kit) to gasket and place in gasket
track on bottom of Flow Control "Sandwich".
4) Place Flow Control "Sandwich" on top of subbase or manifold lining
up all three mounting holes. Electrically operated valves also require
pressing down on flow control to seat electrical plug.
5) Apply a light coating of grease (in kit) to valve gasket and place in
gasket track on bottom of valve.
6) Place valve on top of Flow Control "Sandwich" lining up all three
mounting holes. Electrically operated valves also require pressing
down on valve to seat electrical plug.
7) Assemble valve, flow control and subbase or manifold together with
(3) 1/4-20 screws. Tighten to 35-40 in-lbs. (If valve has a black
plastic cover use the (3) 1/4-20 socket head cap screws. If valve
has a gray metal cover use (3) 1/4-20 button head screws, P/N
H09829. Part number H09829 must be ordered separately).
8) Apply pressure to subbase or manifold and check for leakage at
gasket interfaces. If audible leakage or noticeable bubbling (using
soapy water at joints) is present the gasket probably was accidentally
pushed out of the groove during assembly. If this occurs remove
pressure, disassemble and replace gasket.
ADJUSTMENT PROCEDURES
Adjustment screw nearest to junction box cover on subbase or manifold
controls the flow of air from cylinder port 4 to exhaust port5. With a
double solenoid valve this occurs when operator #12 is actuated. With a
single solenoid valve this occurs when operator #14 is not actuated.
Adjustment screw on other end controls air from cylinder port 2 to
exhaust port 3.
1) Turn both adjustment screws clockwise until fully closed and then
counterclockwise slightly.
2) While cycling valve with cylinder adjust clockwise to decrease speed
or counterclockwise to increase speed.
