Corrosion Resistant Fluorine Ptee Lined Worm Gear Manual Operated Flange Connection Globe Valve for Acid/Alkali

Product Description

Product Description

Our globe valve is a versatile and reliable fluid control component designed for on-off service and throttling applications across industrial sectors. Engineered with a streamlined body structure and precision-machined internal components, it delivers exceptional sealing performance and flow regulation accuracy.

Constructed from high-quality materials—including stainless steel, carbon steel, and alloy steel—the valve offers robust corrosion resistance and durability, adapting to harsh working conditions such as high pressure, high temperature, and corrosive media. It covers a wide range of nominal diameters (DN10–DN300, NPS 3/8–NPS 12) and pressure ratings (PN10–PN400, Class 150–Class 2500), with end connection options including flanged, threaded, and welded to meet diverse pipeline requirements.

The valve operates via a linear-motion mechanism: the handwheel or actuator drives the stem and disc to move vertically against the seat, enabling precise adjustment of flow rate. Its unique seat and disc design ensures tight shut-off to prevent leakage, while the inherent flow restriction provides stable throttling control for liquids, gases, steam, and other media. Available with manual, electric, or pneumatic actuation, it supports both manual operation and automated system integration.

Compliant with international standards like ANSI B16.34, and DIN 3356, our globe valve is widely used in oil and gas,petrochemical, power generation, water treatment, and process industries, delivering consistent performance and long service life for critical fluid control needs.

Product Advantages

1. Precise flow regulation: The linear movement of the disc against the seat enables accurate adjustment of media flow rates, ideal for throttling and process control applications.

 2. Reliable shut-off performance: The tight contact between the precision-machined disc and seat ensures excellent leak-proof sealing, even under high pressure or temperature conditions.

 3. Durable and corrosion-resistant: Crafted from high-quality materials (stainless steel, carbon steel, alloy steel), it withstands corrosive media and harsh operating environments for long service life.

 4. Versatile compatibility: Available in a wide range of sizes (DN10–DN300), pressure ratings (PN10–PN400), and end connections (flanged, threaded, welded) to fit diverse pipeline systems.

 5. Easy maintenance: Compact and simple structural design allows for convenient disassembly, inspection, and repair, reducing downtime and operational costs.

 6. Flexible actuation options: Supports manual, electric, or pneumatic actuation, seamlessly integrating with both manual operations and automated control systems.

 7. Wide media adaptability: Suitable for controlling liquids, gases, steam, and other industrial media, meeting the needs of multiple industries.

How does valve work?

A globe valve operates through a linear motion mechanism to control fluid flow in pipelines, featuring a disc (closing element) that moves vertically against a stationary seat within the valve body.

When opening the valve, the actuator—whether a manual handwheel, electric motor, or pneumatic cylinder—rotates to lift the stem and attached disc away from the seat. This creates a gap between the disc and seat, allowing media such as liquids, gases, or steam to flow through the valve body. The flow rate can be precisely adjusted by varying the height of the disc: a small gap restricts flow for throttling purposes, while a full lift enables maximum flow capacity.

To close the valve, the actuator drives the stem and disc downward, pressing the disc tightly against the seat. The precision-machined sealing surfaces of the disc and seat form a tight seal, preventing media leakage and isolating the pipeline section.

Unlike gate valves, globe valves inherently create some flow resistance due to their Z-shaped or S-shaped internal flow path, but this design enhances their ability to regulate flow with high accuracy—making them ideal for applications requiring precise throttling and process control.
