Overview

The J41F46 Lined Fluoroplastic Globe Valve is a universal valve with a full cavity fluorine lined plastic (usually FEP or similar material) anti-corrosion design and a straight through flow channel valve body. It drives the valve disc vertically up and down along the centerline of the valve seat through the valve stem, achieving reliable opening and closing of the pipeline and flow regulation. The design core of this valve lies in the fact that all surfaces in contact with the medium, such as the inner wall of the valve body, the inner cavity of the valve cover, and the valve disc, are integrally molded or sintered with a dense fluoroplastic lining layer, which enables it to withstand the corrosion of the vast majority of highly corrosive media (such as acids, alkalis, organic solvents, etc.). The valve adopts a standard straight through structure, with constant medium flow direction and low flow resistance, suitable for conventional pipeline layout with limited space, and has both shut-off and basic adjustment functions. The key components of the valve adopt a composite structure of high-strength metal shell and corrosion-resistant lining, and adopt special sealing and structural design to ensure long-term sealing and operational stability under corrosive working conditions. The valve adopts flange connection, with a nominal pressure rating of PN16, and is firmly fixed to the pipeline flange through bolts. Valves can be driven by manual devices (such as handwheels) or matching electric/pneumatic devices to convert input force into linear motion of the valve disc, achieving smooth and reliable opening, closing, and regulating control. This valve is designed specifically for conventional highly corrosive process pipeline systems in industries such as petrochemicals, pharmaceuticals, pesticides, dyes, electroplating, and environmental protection. It is suitable for standard operating conditions that require reliable cutting or simple adjustment of corrosive media, as well as compact and economical structures.

feature

1. Excellent corrosion resistance: All internal surfaces of the valve that come into contact with the medium are lined with a dense layer of fluoroplastic (F46), which has excellent chemical inertness and can withstand the corrosion of most strong acids, alkalis, organic solvents and other highly corrosive media, fundamentally solving the problem of valve corrosion and extending its service life.

2. Reliable sealing and structural design: Combining the straight through flow channel structure with the principle of forced sealing of the globe valve, the sealing pair (valve disc/seat) is made of precision machined fluoroplastic or reinforced material, with excellent sealing performance. The valve cover packing adopts multi-layer corrosion-resistant packing and adjustable clamping structure to achieve effective dynamic sealing and prevent medium leakage.

3. Structural standards and easy installation: Adopting a standard straight through valve body design, the structure is compact, the installation direction is flexible, and it is easy to arrange in straight pipelines. The flange connection (PN16 pressure rating) complies with international standards, is easy to install and has a reliable connection.

4. Stable operation and simple maintenance: The valve stem adopts a lifting design, which ensures smooth transmission and easy manual operation. The fluorine lined structure completely isolates corrosion from the inner lining layer, and the external metal of the valve body does not require special anti-corrosion treatment. Daily maintenance mainly focuses on checking the sealing of the packing, and the maintenance workload is small.

5. Wide applicability and universality: Designed specifically for handling highly corrosive media, it is suitable for routine corrosion conditions in various industries such as petrochemicals, pharmaceuticals, pesticides, dyes, and environmental water treatment. Its standardized design makes it highly versatile and interchangeable.

6. Balancing economy and safety: While providing corrosion resistance similar to the overall special metal valve, the manufacturing cost is significantly reduced. The reliable sealing performance effectively prevents the leakage of dangerous, toxic or expensive corrosive media, ensuring production safety and environmental safety.
