The installation of the valve positioner

Valve positioner valve position detection device connected directly to the control valve stem or the valve shaft, so the feedback signal can be installed to ensure correct, timely reflect the valve position signal and change. Typically, the valve positioner control valve supporting the supply by the manufacturer to complete the connection between the two. , Should ensure that when the production process control need to add a valve positioner valve positioner valve position detection device action is correct, reliable and flexible. The feedback lever fulcrum mechanical clearance should be as small as possible. The valve locator signal lines should be properly connected to the gas supply lines and output lines, enter the line should be marked nameplate.pneumatic accessory
 The valve positioner bit signal should be conducive to the operation and maintenance personnel observations.
Other accessories installation accessories including valve position sensors, solenoid valves, limit switches, the following actuators, electrical converters, the installation shall comply with the relevant provisions of the product specification. Small flow control valves should be installed upstream of the filter. Severe turbulence should be installed in the upstream side of the rectifying means.angle seat valve
