TWT is leading China valve supplier and manufacturer. Through more than 10 years experiences during this industry, we know butterfly valves play a crucial role in controlling fluid flow in various industrial applications. Meanwhile, wafer butterfly valves and lug type butterfly valves offer distinct advantages based on their pressure ratings, size range, valve life, and valve plate materials.
As insider, TWT will explain detail about both of types of butterfly valves. Wafer butterfly valve provide versatility and efficiency, with pressure ratings ranging from PN1.0 to PN1.6MPa and a wide size range from DN50 to DN1200. On the other hand, lug type butterfly valves offer durability and long-lasting performance, with an expected valve life of up to 50 years. They also provide flexibility in terms of valve plate materials, including stainless steel, aluminum bronze, and ductile iron.
I. Wafer Butterfly Valve: Versatile And Efficient
Pressure Ratings (PN1.0～1.6MPa):
- Wafer butterfly valves typically have pressure ratings ranging from PN1.0 to PN1.6MPa.
- This means they can handle moderate to high-pressure applications.Reliable performance and efficient flow control could be referred to pressure rating.
Size Range (DN50～DN1200):
- Wafer butterfly valves are available in a variety of sizes. Popular sizes range from DN50 all the way up to DN1200.
- This versatility allows them to be used in a variety of piping systems. In order to adapt to different flow rates and pipe diameters.
Efficiency and Compact Design:
- The wafer design of these butterfly valves makes them compact and lightweight.If consider to be easy installation and space-saving characteristics, compact and lightweight are important factors.
- Their streamlined flow path minimizes pressure drop and maximizes efficiency.These features are ideal for applications where flow restriction needs to be minimized.
II. Lug Type Butterfly Valve: Durable And Long-Lasting
Valve Life (50 Years):
- Lug type butterfly valves are designed for long-term usage, with an expected valve life of up to 50 years.
- This durability ensures reliable performance and cost-effectiveness over an extended period.This will reduce the need for frequent replacements.
Valve Plate Material Options:
- Lug type butterfly valve offersa variety of valve plate material options. The common choice is about stainless steel, aluminum bronze and ductile iron.
- Stainless steel provides excellent corrosion resistance.This excellent proper is drive stainless steel to be suitable for applications involving corrosive fluids.
- Aluminum bronze offers enhanced strength and durability.It will be a preferred choice for demanding environments.
- Ductile iron provides a balance between strength and cost-effectiveness.Absolutely, it’s a versatile option for various applications.
Secure and Reliable Operation:
- Lug type butterfly valves feature threaded inserts or lugs on the valve body.These threaded inserts make them to be securely bolted onto the pipeline.
- This design ensures a rigid connection, minimizing the risk of leakage and ensuring reliable operation even under high-pressure conditions.
