Butterfly Valve

Introduction

Application

Usage

Butterfly valves are used in the concrete and cement industry to control the flow of dry, powdered, and granular materials from sources like hoppers, silos, and conveyors. They offer a cost-effective and efficient solution for intermittent flow control in gravity-fed or pneumatically conveyed systems, and are engineered with features like dust-tight seals and robust materials for durability in harsh environments.

The cement industry involves handling abrasive, corrosive materials and operating under high-pressure, high-temperature conditions. Butterfly valves, known for their compact design, quick operation, and versatility, are widely used in these harsh environments. The robust design of Butterfly Valves ensures long-lasting performance, making them ideal for applications in cement plants, where performance reliability is paramount.

Valves are essential in cement plants as they control the flow of gases, liquids, and abrasive solids throughout different processes, like raw material handling, grinding, kiln operation, and packaging. These procedures require high temperatures and pressures, and intensely erosive substances, necessitating durable and heat-proof valves. Besides flow regulation, valves facilitate process automation and safety through the provision of remote operation and monitoring capabilities.

Silos and Hoppers:

Butterfly valves are installed beneath cement silos and hoppers to regulate the discharge of powder and granular materials into processing equipment or transport systems.

Conveying Systems:

They intercept and control material flow in screw conveyors, other conveyors, and pneumatic ducting systems. In pneumatic conveying systems, butterfly valves are essential for controlling the flow of materials like cement powder, clinker, and other raw materials. These systems rely on the valve’s ability to withstand abrasive particles while maintaining a smooth flow of materials.

Batching Plants:

They play a crucial role in concrete batching plants, managing the flow of cement and other dry components to the mixing process.

Weighing Bunkers:

Used to control material flow into and out of weighing bunkers for precise measurements.

. Dust Collection Systems:

Cement plants are prone to producing large amounts of dust. Butterfly valves are used in dust collection systems to regulate airflow, ensuring that harmful dust particles are efficiently filtered while maintaining the system's overall performance.

. Clinker Cooling:

Butterfly valves are also used in clinker cooling systems, where they help control the flow of cooling air. Ensuring proper airflow during clinker cooling is essential for maintaining the integrity of the cement product and improving overall operational efficiency.

Material Flow Control:

Their primary function is to open, close, or throttle (partially open) the passage for dry powders and granules.

Efficiency:

They provide a cost-effective and efficient way to manage material flow compared to other valve types.

Dust Containment:

Designed to provide tight sealing, which is essential for controlling dust in powder processing environments.

Robust Construction:

Made from durable materials, such as carbon steel or other alloys, to withstand the abrasive nature of cement and granular materials.

How It Works

Key Features

Specifications and Customization

A disc is rotated a quarter-turn (90 degrees) using a central rod connected to an actuator.
When the disc is parallel to the flow, the valve is open, allowing maximum flow.
When the disc is perpendicular to the flow, the valve is closed, interrupting the material flow.

Aluminum Construction:

The aluminum body provides lightweight yet robust construction, ensuring ease of installation and reducing overall operational weight. The material also offers superior corrosion resistance, which is crucial for handling abrasive and corrosive cement materials.

Cement-Specific Design:

Our butterfly valves are specifically designed to handle abrasive cement powders and other particulate materials. The specialized design minimizes wear and ensures smooth flow control throughout the production process.
