Nibco Butterfly Valves: Diverse Industry Applications

Nibco Buttefly Valves LC-2000 and WC-2000

NIBCO INC., a leader in flow control solutions, presents the LC-2000 and WC-2000 butterfly valves. These models are designed for a variety of applications, with a focus on their specifications, dimensions, and material composition.

Nibco Butterfly Valves Design and Features

The LC-2000 and WC-2000 butterfly valves are crafted with a cast iron body and an extended neck. They incorporate a geometric drive and a molded-in seat liner. These valves are available in both lug and wafer styles, with sizes ranging from 2″ to 12″. They are engineered to be installed between standard ASME Class 125 flanges.

The lug style valves notably offer a 200 PSI bi-directional dead-end service rating without the need for a downstream flange. However, it’s important to note that these valves are not recommended for steam service.

Material Composition

The material composition of these Nibco Butterfly Valves is meticulously selected to ensure durability and efficient performance. The stem is composed of Stainless Steel ASTM A582 Type 416, while the collar bushing is made of Brass ASTM B16. The stem seal and body seal are made of EPDM Rubber.

The nameplate is crafted from Aluminum, and the upper and lower bushings are made of Copper CDA 122. The liner is also made of EPDM Rubber, while the disc is made of Aluminum Bronze ASTM B148 Alloy 955. The body of both the wafer and lug styles is made of Cast Iron.

LC-2000 and WC-2000 Models

The LC-2000 model is a lug style valve featuring an EPDM liner and an Aluminum Bronze disc. Conversely, the WC-2000 model is a wafer style valve, with the same liner and disc materials.

Dimensions and Weights

The dimensions and weights of these valves vary based on their size. For instance, a 2″ valve has a metal rubber square diameter of 3.25″ and weighs between 2.5 to 5.5 lbs, depending on whether it’s a lug or wafer style. On the larger end, a 12″ valve has a metal rubber square diameter of 4.75″ and weighs between 70 to 90 lbs.


These Nibco Butterfly Valves have been third-party certified by QAI to meet the MSS SP-67 standard. They have also been certified by the US Coast Guard “Category A” and are certified lead-free by Truesdail Labs to NSF/ANSI 61-8 Commercial Hot 180°F and NSF/ANSI 61 and 372.

Water Supply and Wastewater Treatment

Butterfly valves, such as the LC-2000 and WC-2000 models from NIBCO INC., are commonly used in water supply systems and wastewater treatment plants. They efficiently control large flow rates and can isolate sections of a system for maintenance or during a system failure. The EPDM rubber seals in these valves provide excellent water-tight sealing.

HVAC Systems

In heating, ventilation, and air conditioning (HVAC) systems, butterfly valves are used to control the flow of coolant or refrigerant. Their compact design and efficient operation make them suitable for these applications.

Fire Protection Systems

Butterfly valves are often used in fire protection systems. They control the flow of water in a sprinkler system, allowing for the isolation of sections of the system for maintenance or in the event of a malfunction.

Chemical Processing

Butterfly valves find their use in chemical processing plants to control the flow of various chemicals through pipelines. The materials used in the LC-2000 and WC-2000 models, such as stainless steel and EPDM rubber, offer good resistance to many chemicals.

Food and Beverage Industry

In the food and beverage industry, butterfly valves control the flow of liquids during processing. They are easy to clean and maintain, which is crucial in these industries to ensure hygiene standards are met.

Oil and Gas Industry

In the oil and gas industry, butterfly valves are used in pipelines to control the flow of oil or gas. They can withstand high pressures, making them suitable for these applications.

Pharmaceutical Industry

In the pharmaceutical industry, butterfly valves are used in processing systems to control the flow of liquids and gases. They are chosen for their ability to maintain a tight seal and resist corrosion.


While the LC-2000 and WC-2000 models are versatile, they are not recommended for steam service. Therefore, they may not be suitable for applications involving high-temperature steam.

In conclusion, butterfly valves like the LC-2000 and WC-2000 models from NIBCO INC. are versatile components used in a wide range of industries and applications. Their robust design, reliable performance, and ability to control flow make them a popular choice in many sectors.
