Pneumatic Connections
6.2.2
A pneumatic actuator typically requires a ¼ inch to ¾ inch air
supply of at least 60 psi (4 bar). Flow boosters will require a ¼
inch to ¾ inch independent air supply from the positioner. Limit
switches or position indicators may be mounted external to a
positioner. Follow appropriate (Actuators, Flow booster) IOM
instructions.

7 Packaging, Transportation and Storage

7.1 Unpacking


While unpacking the valve, check the packing list against
the materials received.

When lifting the valve from shipping container, use straps
through the lifting lugs. Position lifting straps to avoid
damage to tubing and mounted accessories. Valves
equipped with a VR cylinder actuator, lift the valve using
lifting straps or hook through the yoke legs and outer end
of the body.

Contact the shipper immediately if there is shipping
damage.

Call your Flowserve representative if you experience any
problem.

7.2 Packaging and Transport

Packaging includes a cardboard box (with or without a wooden
pallet) or wooden box as needed. Packaging may use
cardboard, plastic wrap, foam, or paper as packaging material.
Filling material may be a carton type or paper.
Shipping marks display packaging dimensions and weight.
Packaging guidelines for export follow HPE standards.

7.3 Storage

Maximum storage time for control valves is six
months.
The packing box begins to break down after 6
months. Leakage may develop.
VAIOM000286-02 (EN/AQ) May 2023
Valtek Valdisk High-Performance Butterfly Control Valves
Store the valve on a solid base in a cool, dry closed room. Until
its installation, the valve must be protected from the weather,
dirt, and other potentially harmful influences.
Do not remove the protective covers from the body flanges of
the control valve or from the instrument ports of the actuator and
accessories until the valve is ready for installation at the site.

8 Installation

8.1 Inspection and Preparation

Ensure that the valve and actuator are being installed as per the
serial number, Purchase order and/or the tag number for the
intended application.
To ensure leak-proof joints, Clean the line of dirt, scale, welding
chips, and other foreign material. Clean the line gasket surfaces
thoroughly.

8.2 Mounting

Selecting the proper fastener material is the responsibility of the
customer. Flowserve 's standard body bolting material is B7/2H.
B8/8 (stainless steel) is optional for applications more than 800°
F / 425° C and with stainless steel or alloy body valves. The
customer therefore must consider the material 's resistance to
stress corrosion cracking in addition to general corrosion.
Periodic inspection and maintenance are required to ensure
fasteners are in proper condition without corrosion. For more
information about fastener materials, contact your Flowserve
representative.

8.3 Valve Installation


Ensure the valve is installed correctly as per the flow
direction indicator on the body. The valve should be
installed in the shaft upstream or downstream configuration
specified on the datasheet. Consult the factory if the valve
must be mounted in a manner other than what is specified
on the datasheet.
When installing the valve in-line
between flanges, make sure the flange
face gasket covers both seat retainer and body surfaces.
Failure to do so will cause excessive leakage. Refer to
Figure 4: A, B and C for seat retainer options and line
gasket position.
