2 Transportation, Storage
2.1 Transportation
Transportation of the valves to their final destination (building site) shall take place in solid crates adapted to the
valves' size. The valves shall be protected against exterior damage and atmospheric exposure.
Depending on the duration of transportation or storage and in view of the conditions, preservation shall take
place by welding valves into PE-film or adding sufficient drying agent or equal.
2.2 Storage
Until final installation the valves shall be stored in a dry, vented area. All function relevant parts shall be suitably
covered against humidity, dust or other contamination.
For longer storage periods or in case of unfavourable storage conditions which might affect later functioning, all
blank surfaces, e.g. stem, piston rod, sealing surfaces shall be suitably protected by long-term preservatives
against corrosion.
Factory applied preservatives shall be checked for possible transport damages and appropriately repaired, if
necessary.
For accessories mounted to the valves, such as electric actuators, limit switches, solenoids, etc., the respective
storage instructions of the manufacturer shall be observed with priority.
3 Installation
3.1

Preparation before installation

Before installation, please make sure that the subject Wey Knife gate valve is in conformance to the service
conditions. The responsibility regarding applied service medium (corrosion resistance, pressure, temperature etc.)
is with the end-user. Please check, if the valve to be installed in an explosion protected area, the valve meets the
rules for the relevant zone.
Not correctly aligned pipelines must, by all means, be corrected before installation in order to avoid tensions or
even cracking of the valve body. Before final installation of the valves, any possibly applied corrosion protec tion
shall be thoroughly removed. All parts, and in particular the gate, stem and piston rod shall be free of dust and
dirt.
