Grooved Butterfly Valve (D81X4, D381X4)

What is the Grooved Butterfly Valve ？What are Grooved Butterfly Valve design standards and connection standards?

A grooved butterfly valve is a type of industrial valve used to control the flow of fluids in pipelines. It typically consists of a disc (or butterfly) mounted on a shaft, which can be rotated to either allow or block the flow of the fluid. The “grooved” aspect refers to the use of grooves or ridges in the valve body, which allows for easy installation using grooved couplings.

Design standards for grooved butterfly valves may vary depending on the manufacturer, but some commonly referenced standards include API 609 for butterfly valves and AWWA C606 for grooved and shouldered joints. These standards provide guidelines for the design, testing, and performance of the valves.

Connection standards for grooved butterfly valves often follow industry-standard grooved pipe coupling specifications. The grooved ends of the valve can be connected to grooved pipe ends using couplings that have matching grooves. One widely used standard for grooved couplings is the Victaulic system, which provides a reliable and efficient method for joining pipes and valves in various applications.

It’s important to check specific product documentation and standards provided by the manufacturer of the grooved butterfly valve you’re working with to ensure compliance and proper installation.

What types of Grooved Butterfly Valve are included?

Grooved butterfly valves come in various types, each designed for specific applications and operational requirements. Here are some common types:

Concentric Butterfly Valve:

The disc and stem are centered within the valve body, providing a streamlined flow path. This design is suitable for a wide range of applications and is the most common type.
Eccentric Butterfly Valve:

The disc and stem are offset from the center, allowing for a more resilient seal and reduced wear. Eccentric butterfly valves are often used in applications where tight shut-off is crucial.
Triple Offset Butterfly Valve:

This advanced design features three offsets: one in the center, one in the shaft, and one in the sealing element. Triple offset valves provide a tight seal with minimal friction, making them suitable for high-pressure and high-temperature applications.
High-Performance Butterfly Valve:

Engineered for demanding conditions, high-performance butterfly valves often feature metal seats, durable materials, and advanced sealing technologies. They are commonly used in industries such as oil and gas.
Resilient-Seated Butterfly Valve:

Designed for low-pressure applications, resilient-seated butterfly valves have a soft seat, typically made of rubber or elastomer, providing a bubble-tight seal. They are commonly used in water and wastewater systems.
Wafer-Style Butterfly Valve:

These valves have a compact design and are often used in applications where space is limited. They are placed between flanges and held in place by the pressure between the flanges.
Lug-Style Butterfly Valve:

Similar to wafer-style, lug-style butterfly valves have threaded inserts (lugs) on the valve body. These lugs allow for easy installation and removal of the valve without disrupting the pipeline.
Double Flanged Butterfly Valve:

These valves have flanged ends on both sides, providing a sturdy connection to the pipeline. They are suitable for applications requiring a higher level of stability and support.
The choice of the grooved butterfly valve type depends on factors such as the application, pressure, temperature, and specific requirements of the system. It’s essential to consult with valve manufacturers and consider the intended use to select the most suitable type for a given application.
