American Standard Stainless Steel Lug Type Wafer Butterfly Valve Import, National Standard D371H Type

American Standard Stainless Steel Lug Type Wafer Type Butterfly Valve Import GB D371H Type

The D371H type lug-style American standard butterfly valve is a new generation of high-performance products developed by our company's technical personnel. The performance of the D373H type lug-style American standard butterfly valve is already at a high level and is widely used in low-pressure, medium-pressure, high-pressure, steel metallurgy, petroleum, chemical, power, and other industrial pipelines for cutting off or regulating medium flow. This American standard butterfly valve adopts a three-dimensional eccentric conical valve seat sealing pair. The disc seal is made of a new metal sheet and elastic material laminated together, embedded in the disc to match the valve seat. The seal is compressed by the swinging of the disc, so the friction resistance of the sealing surface is small, and the closing function becomes tighter as it closes, ensuring reliable sealing performance. When opened, the sealing surfaces completely disengage, ensuring that the sealing surfaces are not damaged. The structural characteristics of the D373H type lug-style American standard butterfly valve eliminate the shortcomings of other types of butterfly valves that cannot seal when over-opened, and it can be used normally at high temperatures, overcoming the shortcomings of other types of valves that are prone to leakage due to thermal expansion at high temperatures. Depending on the medium used, different sealing surface materials are selected for the D373H type lug-style American standard butterfly valve to ensure that the sealing surface is wear-resistant, corrosion-resistant, and has a long service life.

Structure and Dimensions Picture

American Standard Butterfly Valve Structure and Performance Introduction:
The triple eccentric hard seal American standard butterfly valve series products are long-life, energy-saving American standard butterfly valves developed by our company in 1996. The products comply with the national standards JB/T8527-97 (Metal Seal American Standard Butterfly Valve), GB/T13927-92 (General Valve Pressure Test) standards, and other relevant valve standards. This product consists of main components such as the valve body, disc, sealing ring, and transmission mechanism. Its structure is designed using the triple eccentric principle and a new processing technology that combines elastic sealing and hard-soft multi-layer sealing, reducing the torque during operation of the American standard butterfly valve, achieving labor-saving and energy-saving functions. This ensures overall reliability in corrosion resistance, high temperature resistance, and wear resistance.

American Standard Butterfly Valve Main Performance Characteristics:
1. Unique structure, small and lightweight, flexible operation, labor-saving, and convenient; 2. Reliable sealing, achieving gas seal with no leakage;
3. Flow characteristics tend to be linear, with optimal adjustability; 4. Using the triple eccentric principle, the sealing surface is nearly zero wear, extending the valve's service life; 5. Wide range of applications. For example: it can be used for water, steam, oil, air, gas, and other media.
6. Suitable for different temperatures and pressure ratings up to 6.4 MPa, resistant to corrosion and various media pipelines.
