Application Industrial Usage

1、Product Overview

The D371F4-16C is a clamp-on, fully lined butterfly valve specifically designed for applications involving highly corrosive media. It features a midline structure with the interior of the valve body and the surface of the butterfly plate entirely coated with PTFE fluoroplastic, leveraging PTFE's exceptional chemical stability. Combined with the high strength of the carbon steel valve body, this design achieves an optimal balance between structural robustness and corrosion resistance. The worm gear drive mechanism ensures smooth torque delivery and self-locking capability at any position, guaranteeing ease and reliability of operation.

2、Technical Parameters

（1）Product Model: D371F4-16C

（2）Connection Method: Clamp-on

（3）Structural Form: Midline Butterfly Valve

（4）Nominal Pressure: PN1.6MPa (Class150)

（5）Applicable Temperature Range: -29°C to 150°C (dependent on PTFE lining material)

（6）Valve Body Material: Carbon Steel WCB

（7）Lining Material: Polytetrafluoroethylene (PTFE, F4)

（8）Butterfly Plate Material: Carbon Steel WCB (PTFE-coated)

（9）Valve Stem Material: Stainless Steel 2Cr13/304

（10）Drive Mode: Manual Worm Gear (can be fitted with a drive head for electric or pneumatic operation)

3、Core Advantages

（1）Exceptional Corrosion Resistance: With full PTFE lining on both the valve body and butterfly plate, this valve offers resistance to virtually all chemical media (except molten alkali metals and elemental fluorine), making it ideal for highly corrosive fluids such as hydrochloric acid, sulfuric acid, and aqua regia.

（2）Reliable Sealing Performance: The soft sealing structure, combined with PTFE's unique memory and self-lubricating properties, ensures complete shut-off even under low pressure differentials, achieving a "zero leakage" sealing effect.

（3）Effortless Operation: The worm gear drive design not only reduces operational effort but also enables precise flow control. Additionally, its self-locking feature at any opening prevents backflow caused by water hammer effects.

（4）Longevity and Cost-Effectiveness: The carbon steel valve body provides the necessary pressure-bearing strength for pipelines, while the PTFE lining isolates the media from the metal. This design addresses both the high cost of stainless steel valves and the corrosion vulnerability of ordinary carbon steel valves.

4、Application Fields

This valve finds widespread use in industries such as petroleum, chemicals, metallurgy, power generation, pharmaceuticals, pesticides, papermaking, and wastewater treatment. It is particularly well-suited for conveying strong acids (e.g., sulfuric acid, hydrochloric acid, nitric acid), strong bases, organic solvents, and corrosive gases or liquids.

5、Execution Standards

（1）Design and Manufacturing Standard: GB/T 12238 (API 609)

（2）Structural Length Standard: GB/T 12221 (ASME B16.10)

（3）Flange Connection Standard: GB/T 9113 (ASME B16.5)

（4）Pressure Test Standard: GB/T 13927 (API 598)
