Chinese Control Valve With Valve Positioner Prise Of Fisher 3582 And 67CFR Filter Regulator

 Fisher 3582i Single-Acting Pneumatic Positioner

Fisher 3582 pneumatic valve positioners are used with diaphragm-actuated, sliding-stem control valve assemblies. This pneumatic valve positioner receives a pneumatic input signal from a control device and modulates the supply pressure to the control valve actuator, providing an accurate valve stem position that is proportional to the pneumatic input signal.

Features

• The range of the adjustable zero and span permits the use of all standard input signals, including split ranges.
• Because units from one positioner family can be used in a variety of control applications, basic spare parts inventory requirements are simplified and fewer spare parts are needed to support a plant-wide positioner applications base.
• With the cover removed, zero and span adjustments are easily accessible and can be made with a screw driver and spanner.
• Changes in supply pressure and valve load have minimal effect on positioner operation.
• Case, components, and gasket materials are able to withstand harsh environments. Positioner bleed air purges internal parts for additional protection..
• Simple adjustments permit switching between direct and reverse action.
• To support diagnostic testing of valve/actuator/positioner packages with the FlowScanner™ valve diagnostic system, connectors, piping, and other hardware can be installed between the positioner and the actuator.
