Transportation and Storage
Check the shipment immediately upon receipt for completeness of delivery and transport
damage. Furthermore, it should be ensured that the valves and possibly mounted
actuators have not been damaged during transport. Please also check that the supplied
valves (types, nominal sizes etc.) correspond with the order. KLINGER Fluid Control is to
be notified immediately of any kind of deviations. Regarding damage obviously resulting
from transportation, please contact the freight forwarder in charge of delivery.
Valves and valve replacement parts may only be stored in dry storage areas. Fully
assembled valves must be stored in the condition as supplied to the customer (valve in
CLOSED position, connections covered with protective caps). Valve replacement parts
must be handled with care and should remain as packaged by the factory during storage.
»
Storage in the default factory packaging.
»
The valves are to be stored in closed rooms, in a non-aggressive atmosphere,
and protected against humidity and contaminants.
»
In the event that protective sheeting or shrinking foils are used, it must be
ensured – through adequate measures – that the atmosphere within the covers
remain free of condensation.
»
Corresponding protective measures are recommended for storage in dusty
rooms.
»
In order to avoid mix-ups, all stored parts should be labeled in accordance with
the shipping notes and stored in the correct place.
»
The temperature in the storage rooms should not exceed the limits
-
20 °C and
+50 °C. Rapid temperature changes are to be avoided whenever possible
(condensate water).
»
Possible changes originating from KLINGER Fluid Control and having an impact
on storage will be announced in a timely manner in the form of a circular.
»
The operation manual is part of the delivery and must be stored with the item.
This ensures that all important information and documents can be passed on.
»
Lift lines suitable for the weight and the lifting aids on the valve (to the extent
present) are to be used for manipulation purposes.
Damages resulting from incorrect storage or manipulation free KLINGER Fluid Control
from any obligations derivable from the warranty, guarantee and product liability.

Operating Principle and Mode of Operation
Piston valves are closed clockwise and opened counterclockwise. Care should especially
be taken during the closing process, i.e. the handwheel should be turned until it rests
against the bonnet. As opposed to globe valves, piston valves require no increased end
torque. As a result of the construction of piston valves, it is possible to achieve tightness
prior to reaching the CLOSED position. In order to protect valve rings from taking
damage, piston valves must always be closed as far as they will go.
