Grooved Butterfly Valve Manufacturer
Grooved butterfly valve is a type of valve used to regulate or isolate the flow of fluids in a pipeline. The valve is characterized by a grooved connection on the valve body, which allows it to be installed without the need for flanged connections. It typically features a disc that rotates within the valve body to control the flow of liquid or gas.
Grooved Connection: The valve is installed using a grooved pipe connection, which provides a secure, leak-proof seal without the need for welding or threading.
Butterfly Design: The valve operates by rotating a flat, circular disc (butterfly) inside the pipe to control the flow. When the disc is perpendicular to the flow, the valve is closed; when the disc aligns with the flow, the valve is open.

Grooved Butterfly Valve Installation
Grooved butterfly valve has grooved ends that allow for quick and easy installation without the need for flanges, welding, or threading. Instead, you connect the valve directly to the pipeline using grooved couplings.
This connection method is very common in fire protection, HVAC, water supply, and industrial piping systems because it is easy to install and maintain.To make a secure, leak-free connection, you need to use grooved butterfly valves with grooved pipe couplings. There are two main types:
Rigid Coupling Provides a solid, non-flexible connection that prevents movement or vibration.Used in systems where you need a fixed, stable connection like fire protection and industrial pipelines.
Flexible Coupling Allows for a little movement to accommodate thermal expansion, contraction, and vibration.Ideal for systems where you need a little flexibility like HVAC and piping that is subject to seismic activity.
Installation Steps
Preparation Make sure the grooved ends of the valve and the pipe meet the standards (e.g., AWWA C606).Check the sealing gasket and couplings for damage or defects.Clean the grooved ends to remove any dust, debris, or rust.
Position the Gasket Put the rubber gasket (usually EPDM for water, NBR for oil, or Viton for high-temperature chemicals) around the grooved end of the pipe or valve.Make sure the gasket is seated properly to ensure a tight seal.
Attach the Coupling
Rigid Coupling: Align the two grooved ends and put the metal housing over them. Tighten the bolts evenly to lock the connection.
Flexible Coupling: Install the coupling the same way, but make sure you leave some flexibility for movement.
Final Check & Pressure Test
Make sure the bolts are fully tightened and torqued evenly.
Pressure test the system to make sure you have a leak-free connection.
Grooved Butterfly Valve Selection Guide
Selecting the right grooved butterfly valve involves considering several key factors, including pipeline size, working pressure, medium type, and industry standards. Below is a detailed selection guide to help customers choose the most suitable valve for their specific applications.
1, Pipeline Size & Compatibility
Grooved butterfly valves are typically available in DN50-DN600 (2”–24”), with some manufacturers offering larger sizes.
The groove dimensions must comply with international standards (e.g., AWWA C606) to ensure compatibility with grooved pipe couplings.
For larger pipelines, check if actuation options (manual, gear-operated, pneumatic, or electric) are available.
2, Working Pressure Ratings
The pressure rating of a grooved butterfly valve depends on the system’s requirements:
