Operation, Parts, and Instruction Manual
NOTICE These instructions are meant to be used with the Dyna-Flo 590 Technical Bulletin as they refer to Figures
and Tables therein. If you do not have the Technical Bulletin, contact Dyna-Flo immediately, or visit
www.dynaflo.com
Each control valve is factory checked. Check the calibration for the specific application, before a valve
is put into service.
It is the intention of this document to provide users with an accurate guide for safe installation and
maintenance of the 590 Control Valve. Revisions and updates are available at above mentioned website.
GENERAL
The following instructions are to be thoroughly reviewed and understood prior to installing, operating or performing
maintenance on this equipment. Work on this equipment should be performed by experienced personnel. Throughout
the manual, safety and caution notes appear and must be strictly followed, to prevent serious injury or equipment
malfunction.
SCOPE
The control valve configuration and construction materials were selected to meet particular pressure, temperature, and process
conditions. Some material combinations are limited in their pressure and temperature ranges. Do not apply any other conditions to
the valve without first contacting your Dyna-Flo sales office.
This manual is written to be a practical and useful guide maintaining the Dyna-Flo 590 Control Valve.
SAFETY CAUTION
Only well trained experienced technicians should perform these procedures. Use safe work practices and lock out
procedures when isolating valves and actuators. It is also important to wear the proper protective equipment when
performing any installation or maintenance activity. Use only parts and materials rated for the process being used,
operating conditions, and environmental conditions products will be used in.
To avoid personal injury or installation damage as a result of the sudden release of process pressure or damage to
equipment, do not install the valve assembly where service conditions could exceed the limits stated in this manual,
sales bulletin or on the equipment nameplates. Use government codes, accepted industry standards and good piping
practices, and select proper pressure-relieving equipment for protection of your installation. Always be aware of
flammable process and instrument gas.
Always be aware of the hazards of actuators, especially spring-loaded actuators. Be sure that the actuator is
de-energized or in the failed position before performing any maintenance procedure.
These valves have dangerous pinch points. Never put your hands inside the valve unless you are certain that the ball
cannot rotate.

Operation, Parts, and Instruction Manual
UNPACKING VALVE FROM SHIPPING
CONTAINER
Special Tools Required:
• Properly Rated Lifting Straps (2 – 4 Straps) See Table 2 for
valve weights.
• Lifting Device (Example: Crane)
Check the packing list, verify that the list includes all the
materials in the shipping container before unpacking.
Place the lifting straps around the neck of the actuator and
valve body (See Figure 2). Straps should be placed to avoid
damage to tubing and other mounted accessories.
INSTALLATION
Before You Begin:
• Read the General and Scope section of this manual (Page 2).
• Read Safety Caution (Page 2).
• Place the valve into the OPEN position, this helps to prevent
damage to the valve ball (Key 2) during installation.
• Sudden movement of actuator can cause damage or injury.
It helps to have the actuator de-energized as long as the
valve remains in the OPEN position.
• Use safe work practices and lock out procedures before
placing valve in-line.
Parts Required:
• Flange Studs (Key 51) Note: Flange Studs will need to span
the distance from one line flange, across the valve body, and
though the other line flange. (See Table 3 & 4 for stud
lengths & Figure 3 for stud placement)
• Long Cap Screws (Key 53) Note: Long Cap Screws pass
through the line flanges and thread directly into the valve
body. Long Cap Screws will be required for the outlet side of
the valve for single seal valve configurations. (See Table 3 &
4 for cap screw length and Figure 3 for cap screw placement)
• Short Cap Screws (Key 52) Note: Short Cap Screws pass
through the line flanges and thread directly into the valve
body. (See Table 3 & 4 for cap screw length and Figure 3 for
cap screw placement)
• Appropriate Line Flange Gaskets.
LIFTING STRAP
LIFTING STRAP
Installation Steps:
1Clean dirt, welding chips, scale, or other foreign material
from the line and flange surfaces.
2Valve may be installed in any orientation, although to
reduce stress and wear on valve assembly it is
recommended that valve be installed with the valve shaft
(Key 17) horizontal to the ground.
3 For Single Seal Construction
Center the valve in-line as indicated by flow arrow (See
Figure 37 & 38), standard flow direction has the seal
protector ring (Key 26) facing up stream.
For Dual Seal Construction
Center the valve in-line so the flow direction with the
highest pressure matches the direction of the flow arrow
(see Figure 36, 37, 38).
4Install the line flange gaskets.
5Apply anti-seize compound (Key A) to the threads of the
flange studs (Key 51) and cap screws (Keys 52 & 53).
6Tighten the flange studs and cap screws in even
increments in a crisscross pattern until the correct line bolt
torque specification is reached.

WARNING:
Property damage, environmental harm, and personal injury can result from the use of supply gas other than clean,
non-corrosive, oil and moisture free air. Do not exceed the supply pressure indicated on the serial plate located on the actuator.
Before You Begin:
Note: Standard actuators accept ¼” (6 mm) NPT connections.
• Refer to the appropriate actuator instruction manual when necessary.
Piping Installation Steps:
1Use 3/8” (outside diameter) tubing (or equivalent) for air lines.
2Install the required line vents, valves, drains, seals, and filters to the actuator.

Operation, Parts, and Instruction Manual
PERIODIC INSPECTION
Special Equipment Required:
• Bypass or block valves.
Before You Begin:
• Read Safety Caution (Page 2).
• Use safe work practices and lock out procedures.
• Disconnect supply lines (air or gas), electric power, or control
signal to the actuator. Sudden movement of actuator can
cause damage or injury, make sure actuator will not operate.
• Vent any pneumatic actuator loading pressure and relieve
any actuator spring preload if present.
• Relieve process pressure and drain the process fluid from up
and down stream of valve.
• Be aware of potentially hazardous process material that may
be present in-line and in-valve. Isolate the valve from
process pressure. Use a bypass or block valve if necessary,
or completely shut off the process. For dual seal valves,
relieve internal pressure by removing the pipe plug (Key 37).
See Figure 38 on Page 32.
Inspection Steps:
1Check for visible signs of leakage around all seal and
gasket areas.
2Check the valve for damage, especially damage caused by
corrosive fumes or process drippings.
3Clean and repaint the areas as required.
4Ensure all accessories, mounting brackets, and fasteners
are secure.
5Clean any dirt and foreign material from the valve shaft
(Key 17).
MAINTENANCE
Note: Shaft seals or live loaded packing and ball seals (Key 30)
should all be inspected frequently for leaks, wear and
damage. Maintenance to the shaft seals or live loaded packing
can be made while the valve is still in-line, the actuator must
be removed for drive shaft (Key 17) seal/pacing maintenance
(See Page 12 for Actuator Removal instructions).
Note: Perform ball seal (Key 30) maintenance when the control
valve will not properly shut off. Ball seal maintenance can be
performed without removing the actuator from the valve. Ball
seal maintenance cannot be performed with the valve in-line.
When removing the valve from pipe line be sure it is in the
OPEN position, verify the valve is open using the indicator
scale (Key 24) before removing from line.
Note: When testing the seal integrity of the valve using the
pipe plug port (dual seal configuration), it is recommended that
the pipe plug (Key 37) be replaced by a hand valve. A hand
valve will allow valve pressure to be relieved safely during
seat leak rate testing. See Figure 38 for pipe plug location.
Before You Begin:
• Read Safety Caution (Page 2).
• Determine if valve has shaft seals or live loaded packing
(See Figures 31 & 37).
• Determine if valve is single seal or dual seal (See Figures 37
& 38).
• Follow Steps 2 – 5 of PERIODIC INSPECTION Before you
begin.
SHAFT SEAL MAINTENANCE
Note: It is recommended that the follower shaft seal and the
drive shaft seal be replaced at the same time. The actuator
must be removed for drive shaft seal maintenance. For live
loaded packing see Page 25.
Special Tools Required:
• Mechanics Pick Set
Lubricants Required:
• Anti-Seize Compound (Key A)
• Silicone-based O-Ring Compound (Key B)
• White Petroleum Grease (Key C)
