Product details
J41F3/J45F3-J44F3 Fluorine lined Plastic Stop Valve Introduction:
J41F3/J45F3-J44F3 lined with fluoroplasticDivided into straight through fluorine lined globe valves, direct flow fluorine lined globe valves, and angle fluorine lined globe valves, they have the advantages of compact structure, flexible opening and closing, strong corrosion resistance, and short stroke (generally 1/4 of the nominal diameter). They are widely used in pipeline systems such as petroleum and chemical industries to cut off the medium. However, it should be emphasized that fluorine lined globe valves are strictly prohibited from adjusting the flow rate to prevent high-speed medium flow generated at the throttle outlet from eroding and damaging the sealing surface.
J41F3/J45F3-J44F3 Fluorine lined Plastic Stop Valve Features:
1. Plastic lined J41 straight through, J45 straight slip, J44 angle globe valves have the advantages of compact structure, flexible opening and closing, strong corrosion resistance, and short stroke (generally 1/4 of nominal diameter). Widely used as a cut-off medium in pipeline systems such as petroleum and chemical industries, plastic lined globe valves are strictly prohibited from flow regulation to prevent high-speed medium flow generated at the throttling port from eroding and damaging the sealing surface.
2. The valve disc and valve stem are designed as an integrated structure to prevent the possibility of internal components rushing out of the valve body due to pressure fluctuations in the pipeline. The structure is compact and safe to use.
