Powder pneumatic butterfly valves
Powder Butterfly Valves are ideal for all types of bulk solids processing plants where interception of gravity-fed or pneumatically conveyed dry powders or granules is required. These valves feature an aluminum alloy body, 304 Molecular Material disc, stainless steel stem, and NBR and EPDM seats. The size range is from four inches to sixteen inches in diameter (100mm – 400mm) and the flange accommodates EN 1092 PN 6/PN10/PN16, ASME Class 150, AS 4087 PN 10/PN 16, JIS 5K/10K and ISO5211 flanges. Additionally, the valves have a temperature range of -40 °C to +120 °C depending on pressure, medium and material. Moreover, these valves are lightweight and easy to handle due to their special design and interchangeable discs which make them easy to fit as well as highly abrasion resistant with quick maintenance capabilities. Furthermore; this product includes a pneumatic actuator with output torque ranging from 10Nm to 8000 Nm when paired with double acting single acting normally closed actuators or single acting normally open actuators plus various pneumatic accessories such as solenoid valves, limit switch boxes, filters, E/P positioners and hand wheels.
Powder Butterfly Valves are used in all types of bulk solids processing plants where interception of gravity-fed or pneumatically conveyed dry powders or granules is required. VFS Butterfly Valves can be fitted beneath hoppers, bins, silos, screw or other type conveyors, or for material interception in pneumatic conveying ducts. Due to their special design and to the engineering materials used, they represent a particularly economic yet most efficient solution.

What is the valve used for powder?
The valve is an essential component of a powder processing system, as it controls the flow of material into and out of various sections and chambers. In particular, pneumatic valves are often used to open and close at high speeds for complete filling or emptying in controlled amounts. They are primarily used in powder handling systems such as food processing, pharmaceuticals, chemical plants, paint booths, coating operations and airflow control applications.
Application of Silo Butterfly Valve in Cement Industry
The butterfly silo valve is a reliable choice for industrial applications, including those in the cement industry. It provides an efficient and cost-effective solution for controlling and managing flow while ensuring that dust does not escape from the hopper. Furthermore, the butterfly valve’s design allows it to be used in tight spaces such as those found in cement factories.
The silo butterfly valve has many advantages when used in a cement factory. Its design makes it suitable for both gravity and pressure installation, allowing optimal conditions within the system. The range of materials available also ensures that it can be tailored to suit specific needs within a cement plant, such as abrasive products or highly corrosive ones. This valve’s lightweight construction further aids its easy installation and removal without any damage to existing structures or systems.
Application of Silo Butterfly Valve in Powder Industry
Silo butterfly valves are a versatile and highly effective type of valve used in powder industries. The silo butterfly valve is widely used for controlling the flow of powders and other granular materials in many industrial applications, such as chemical, power plant, oil & gas, iron & steel, food and pharmaceutical industries.
The design of the silo butterfly valve ensures its suitability to work effectively with a wide variety of material properties and bulk densities. This makes it an ideal choice for many different types of media handling operations, including those involving dusty environments or hazard gases that require tight shut-off features from safety valves.
