INSTRUMENT OPERATION
The 47xxP/E positioners function is to make a valve stroke proportional to a pneumatic or electrical control signal
from a controller, or to modify the natural flow characteristic of the valve itself through the use of a characterized
cam.
The 47xxP/E pneumatic positioner design is based on the force-balance principle: the signal pressure exerted on a
diaphragm is opposed by a feedback spring. In the balanced state, when the pneumatic signal varies, the diaphragm
assembly moves. This movement is followed by the pilot plug which is opposed by the pilot spring.

PROTECTION, STORAGE, HANDLING, DISPOSAL
Valves have been tested and adjusted at the factory prior to shipment. The period between leaving the manufacturing plant to installation may involve
substantial exposure to degradation due to impact, impingement or corrosion. Such degradation can adversely affect the performance of valves when
in service and can easily be avoided if simple guidelines are followed.
Protection
As a minimum,all positionersare dried, coated and fitted with protective measures,such as positional air connection protection and boxed for protection
during shipment when shipped as individual positioner, or waterproof wrapping if installed on valve package, prior to shipment. This protection should
be left in place until immediately before the positioner is to be fitted onto an assembly.
Storage and Preservation
If the 47xxP/E is stored for a long duration, you must keep the housing sealed against weather, fluids, particles, and insects. To prevent damage to the
47xxP/E:
•Use the plugs provided with shipment to plug the ¼ NPT air connections, on the positioner and on the air filter regulator set.
•Do not allow standing water to accumulate.
•Observe storage temperature requirements
Transportation and Handling
Appropriate care when handling the 47xxP/E should be given, roughness in handling may damage air filter and NPT connection. Care should be taken
to avoid damage to any protection. Exercise care when unpacking the control valve and its mounted accessories.
Disposal
Follow instructions carefully on product labels for use and storage to prevent any accidents.
Be sure to read product labels for disposal instructions to reduce the risk of products exploding, igniting, leaking, mixing with other chemicals or posing
other hazards on the way to a disposal facility.
Never store hazardous products in food containers; keep them in their original containers and never remove labels. Corroding containers, however,
require special handling. Call your local hazardous materials official or fire department for instructions.
Check with your local environmental, health or solid waste agency for more information on waste management options.
