Adjusted pneumatic valve installation considerations

. Regulating pneumatic valve before installation to sewage pipeline, antirust oil and welding slag cleaning etc. ; After installation, pneumatic valve should be in the biggest opening of piping, pneumatic valve and clean and test of each joint sealing, in order to avoid run-time binding occur or damage the pneumatic valve core, pneumatic valve seat.
. Should be installed near the ground or floor, so that the maintenance; For half a pneumatic valve positioner or pneumatic valve handwheel institutions, should guarantee the observation, convenient adjustment and operation.
. When installation, should make the flow direction of medium and pneumatic direction arrow on valve body.
. When installation should avoid to bring additional stress to adjust the pneumatic valve, in order to avoid because of the influence of the temperature or weight to adjust the pneumatic valve flange deformation and breakage, when regulating pneumatic valve installed in the pipeline is long, support should be installed, and the special use on the occasion of vibration must be to support or take corresponding measures of vibration absorber. The regulation of large diameter pneumatic valve installation should avoid tilt, prevent the pneumatic valve mechanical wear of internal parts and packing leakage, should pay special attention to this.
. To be on the safe side, pneumatic regulating pneumatic valve should add bypass line ( Important occasions) In order to adjust the pneumatic valve failure or maintenance, don't stop production.
. Equipped with a handwheel institution, may carry on the manual operation of pneumatic valve, pneumatic valve opening can also be used to limit. When using automatic control, must put the handwheel institutions in neutral position.
. Pneumatic valve for high temperature, should every three months to the packing part injection embellish grease.
