Do not lift or support extended spring
cap while lifting the entire valve, this
can cause the O-ring to slip and result in leakage. The
lifting lug on spring cap should be used for lifting only the
actuator after dismantling from valve body.
For applications, where unusually high spring thrusts are
required, Flowserve offers the Valtek VR extended spring for
sizes VR25, VR50 actuators and dual springs for sizes VR100,
VR200 actuators.
Using many of the same design concepts as the Valtek VR
extended spring actuator offers external spring cap. This
allows for extra-long springs which provide extra force. The
Valtek VR standard, extended spring and dual actuator section

6. Packaging and Transport
Careful packing, loading and transport arrangements are
required to prevent products from being damaged during
transport. Standard packaging includes a cardboard box, with or
without a wooden pallet base as needed. Special packaging
may include a wooden box. Packaging may use cardboard,
plastic wrap, foam, or paper as packing material. Filling material
may be a carton type or paper.
Shipping marks display product and package dimensions and
weight (for further information see Packaging and Sending
Instructions, Form L 002). Packing guidelines for export follow
HPE standards. (Nonreturnable packaging may contain up to
90% recyclable materials.)
7. Storage
Rubber become brittle, lubricants become
resinous, see also ISO 2230.
Upon arrival on site, store the Valtek VR actuator on a solid
base in a cool, dry closed room. Until its installation, the actuator
must be protected from the weather, dirt and other potentially
harmful influences.
Do not remove the protective covers from the air supply
connection of the actuator or from the instrument and
