Butterfly Valve

eQUIP manufactures butterfly valves for controlled shut-off and flow control of powders, granules and dry bulk materials in industrial handling systems. These valves are designed for silo outlets, hopper discharge points, screw conveyor inlets, loading systems and powder processing lines where reliable open-close operation and dust-tight performance are required.

Product overview

A butterfly valve uses a rotating disc inside the valve body to open or close the material flow path. In dry bulk applications, it helps control the discharge of cement, fly ash, lime, mineral powders, granules and similar materials from silos, bins, hoppers or process equipment.

Depending on the application, the valve can be supplied with manual lever operation, pneumatic actuator operation, suitable inlet and outlet flanges, sealing options, body material selection and surface treatment according to project requirements. It can be integrated with screw conveyors, loading bellows, rotary valves, silo discharge systems and other bulk material handling equipment.

What It Does

A butterfly valve is used to open, close or isolate the flow of dry bulk materials at silo outlets, hopper discharge points and process equipment connections. When the disc rotates, the valve either allows material to pass through or blocks the flow path.

In powder handling systems, butterfly valves are commonly used as compact shut-off valves under silos or above screw conveyors, loading bellows and discharge equipment. They help support controlled discharge, cleaner operation and safer maintenance access.

How to select

Technical Flexibility

The design of a butterfly valve depends on the material type, valve diameter, installation position, flow characteristics, operating frequency, sealing requirement and actuation method. eQUIP can configure the valve body, disc, seal, flange connection, operating mechanism and surface protection according to the project.

For abrasive powders such as cement, fly ash or mineral materials, suitable material selection and wear-resistant options can be considered. For automated operation, the valve can be supplied with a pneumatic actuator, position indicator, limit switch box and control accessories according to the plant requirements.

FAQ

What is a butterfly valve?

A butterfly valve is a valve with a rotating disc used to open, close or control the flow path. In bulk material handling systems, it is commonly used for powders, granules and dry bulk materials at silo outlets and hopper discharge points.

Where is a butterfly valve used in powder handling systems?

Butterfly valves are commonly used under silos, hoppers and bins, or above screw conveyors, loading bellows, rotary valves and discharge equipment.

Can a butterfly valve be used for cement and fly ash?

Yes. Butterfly valves can be used for cement, fly ash, lime, mineral powders and similar dry bulk materials. The correct body material, seal and actuation type should be selected according to the material and operating conditions.

What is the difference between a butterfly valve and a rotary valve?

A butterfly valve mainly opens, closes or isolates the material flow. A rotary valve is used for controlled feeding, dosing or airlock operation. These products have different functions in bulk material handling systems.

Can the butterfly valve be operated pneumatically?

Yes. A butterfly valve can be supplied with a pneumatic actuator for automated open-close operation. Manual lever operation can also be used depending on the application.

Is this butterfly valve used for water or liquid pipelines?

This product is designed for dry bulk material handling applications such as cement, fly ash, lime, mineral powders and granules. It is not positioned as a plumbing or water pipeline valve.

What affects butterfly valve price?

The price depends on valve diameter, body material, seal type, actuation method, flange connection, surface treatment, automation accessories and project-specific requirements.
