J45F46 fluorine lined globe valve

J45F46 fluorine lined globe valveProduct Introduction

J45F46 fluorine lined globe valveIt is a type specifically designed forHighly corrosive mediumThe core advantage of the designed cut-off valve lies in the fluoroplastic lining (such as PTFE, FEP, etc.) covering the inner cavity of the valve body and the surface of key components. It can withstand working conditions of -50 ℃ to 150 ℃ (some models can reach 180 ℃) and is suitable for various concentrations of strong acids (aqua regia, sulfuric acid, hydrochloric acid, hydrofluoric acid), strong alkalis, strong oxidants, and organic solvents. This valve is mainly used in pipeline systems such as petroleum and chemical industriesCut off the flow of the medium，Strictly prohibited for use as a flow regulatorTo prevent high-speed medium flow from eroding the sealing surface.

Structural features and design advantages

structural form

Belonging to a DC type globe valve, with low flow resistance coefficient, the medium flows in a straight line, reducing pressure loss.

Together with the straight through type (J41F46) and angle type (J44F46), it forms the fluorine lined globe valve series, suitable for different pipeline layout requirements.

Core design highlights

Integration of valve disc and valve stemTo prevent pressure fluctuations in the pipeline from causing internal components to flush out and improve safety during use.

Compact opening and closing structureShort travel (usually 1/4 of the nominal diameter), flexible opening and closing, saving operation time.

Fully lined fluorine anti-corrosionThe valve body, valve cover, valve disc and other parts in contact with the medium are lined with fluoroplastics (such as FEP/F46), which have excellent corrosion resistance.

J45F46 fluorine lined globe valveProduct installation and maintenance

Installation precautions

storage conditionsWhen the valve is not in use, the valve disc should be kept in a slightly open state and stored neatly in a ventilated and dry warehouse. Stacking and outdoor storage are strictly prohibited.

Inspection and CleaningBefore installation, carefully check whether the valve markings and certificate of conformity meet the usage requirements, and check whether the packing is tightly compressed to ensure the sealing of the packing, while not hindering the rotation of the valve stem. Check the inner cavity and sealing surface of the fluorine lined globe valve. If there is dirt, it should be wiped clean with a cleaning cloth.

Installation directionDuring the installation process, it is not allowed to damage the fluorine lined sealing surfaces at both ends. Attention should be paid to keeping the direction of the valve body arrow consistent with the direction of the fluid medium.

Pressure testing requirementsDuring the pressure test of the system or pipeline after installation, the fluorine lined globe valve should be in the fully open position.

Maintenance precautions

regular inspectionLong term stored fluorine lined globe valves should be regularly inspected to remove dirt, with special attention paid to the cleanliness of the sealing surface to prevent damage.

Lubrication and maintenanceWhen in use, lubricant should be regularly injected into the trapezoidal thread of the valve stem.

Fault handlingDuring use, if a malfunction is found, it should be immediately stopped, the cause identified, and eliminated.

Operating SpecificationsWhen opening or closing the manual fluorine lined globe valve, the handwheel should be used instead of auxiliary levers or other tools.

Maintenance of transmission deviceFor electric and pneumatic transmission devices, their storage, maintenance, installation, and use should refer to the instruction manual for the electric device of the fluorine lined globe valve.
