The Long Neck Wafer Type Model 25 Butterfly Valve is a specialized flow control device designed for use in piping systems where precise regulation of fluid flow is critical. This valve is available in sizes ranging from 1 inch to 12 inches, making it suitable for a wide array of industrial applications. The product is offered in two primary configurations: wafer type model 15 and model 25, and lug type model 20 and model 30 body, providing flexibility for different installation requirements.


The Long Neck Wafer Type Model 25 Butterfly Valve is constructed from premium-grade materials, including stainless steel sanitary butterfly valve and ss body butterfly valve components. These materials ensure resistance to corrosion, wear, and high-temperature environments, making the valve suitable for harsh industrial conditions. The use of stainless steel also aligns with the NIST standards for material integrity and precision, as highlighted in their research on industrial material performance (NIST).
The valve's design allows it to be adapted for various industries, including food and beverage processing, pharmaceuticals, chemical manufacturing, and water treatment. The ss 304 butterfly valve variant is particularly favored in sanitary applications, where cleanliness and contamination prevention are paramount. This versatility is a testament to the company's commitment to meeting diverse customer needs.
Engineered with a long neck design, the Model 25 butterfly valve provides improved flow control accuracy. This feature is critical in applications requiring precise regulation of fluid flow, such as in chemical dosing systems or pharmaceutical production lines. The valve's design minimizes turbulence and ensures smooth operation, contributing to energy efficiency and reduced maintenance costs.
Designed for user-friendly installation, the wafer and lug types of the valve simplify integration into existing piping systems. The pvdf butterfly valve variant further enhances ease of maintenance due to its lightweight construction and resistance to chemical degradation.
