• After removing from box, always store the
valve under roof and in a dry and clean
atmosphere, protected from rain and storm.
• Always place the valve on ‘soft’ surface like
rubber sheets or wooden planks free of dirt/
debris/hardware like nails and moisture to
avoid damage to the valve surfaces.
• Ensure that valve ends are covered with
protective end caps. Do not remove any
protection from the valve during storage
period.
• In case of automated valve assembly, refer to
actuator/accessory manufacturer instructions
for handling and storage.
