Key Features and Advantages

1. Durable Construction

The valve is constructed using high-quality materials to ensure longevity and resistance to corrosion. The body is available in cast iron (ASTM A126 CL. B) or ductile cast iron (ASTM A536 65-45-12), providing robustness for harsh environments. The stem and disc are made from stainless steel (ASTM A276 Type 316, 410, 420) or AL-Bronze (ASTM B148 C95400), enhancing its performance in corrosive media.

2. Versatile Sealing Options

The valve offers multiple sealing materials, including NBR, EPDM, Neoprene, PTFE, and Viton, to accommodate different fluid types and operating conditions. The use of O-rings and bushings made from PTFE, Nylon, or lubricated bronze ensures a tight seal and reduces friction during operation.

3. Precision Engineering

Manufactured to strict dimensional standards, the valve ensures compatibility with existing piping systems. The dimensions list (in both inches and millimeters) guarantees accurate installation and optimal performance. For example, the 12" size has a body diameter of 300 mm and a flange thickness of 31.8 mm.

4. Easy Maintenance

The valve's design allows for straightforward maintenance, with accessible components such as the upper stem, lower stem, and spring pin. This reduces downtime and ensures cost-effective long-term operation.

Technical Specifications

The Long Neck Wafer Type Model 25 Butterfly Valve is available in sizes from 1" to 12", with detailed dimensions provided for both imperial and metric measurements. For instance, the 2" size has a flange diameter of 27/8 inches (73 mm) and a body length of 11/4 inches (32 mm).

Applications

The Long Neck Wafer Type Model 25 Butterfly Valve is widely used in industries requiring precise flow control, including:

• Water Treatment: Ideal for regulating water flow in municipal and industrial water systems.
• HVAC Systems: Ensures efficient control of heating, ventilation, and air conditioning systems.
• Chemical Processing: Resists corrosion and handles aggressive chemicals in manufacturing processes.
• Oil and Gas: Provides reliable shut-off and flow control in pipelines and storage tanks.
