Many achievements at cement plants! It is used in various plant facilities related to cement and steelmaking.

We would like to introduce a case of delivering the "Slat Valve," handled by Matsushita Environmental Industry Co., Ltd., to a cement factory. We supplied a product for the quantitative supply of fly ash for cement factories. This product is a powder quantitative feeder that delivers a nearly constant amount of various powders per unit of time. 【Slat Valve Features】 ■ A shape similar to a vertical rotary valve ■ The rotor is fixed and does not rotate (does not mix the powder) ■ The upper and lower valve plates rotate coaxially, allowing powder to enter and be discharged in a measured amount *For more details, please download the PDF or feel free to contact us.

Presentation of comparison table with rotary valves: Non-leaking slat valve.

Presentation of comparison table with rotary valves: Non-leaking slat valve.

Sliding only on the two surfaces of the upper/lower valve plate! It can be directly mounted to the upper storage tank, making it compact.

The "slat valve" is a powder dosing machine with excellent sealing properties. For powder dosing machines, table feeders and rotary valves are commonly used, with various products available from multiple companies. While there are many advantages to the slat valve compared to these, we take pride in its particularly high sealing performance. Additionally, we have numerous delivery records at a powder transport pressure of around 30 kPa. 【Features】 ■ Excellent dosing accuracy ■ Durable structure that is resistant to wear, allowing for long-term operation ■ Capable of forced discharge even for powders with high moisture content or those that tend to stick ■ No flushing occurs even when the powder is fluidized ■ System-specific operation *For more details, please download the PDF or feel free to contact us.

Presentation of comparison table with rotary valve: Powder and granule supply device slat valve.

Presentation of comparison table with rotary valve: Powder and granule supply device slat valve.

Prevent leakage of powder particles and contribute to improving the working environment! It boasts excellent sealing properties and high durability. A comparison table with rotary valves is also available.

The "Slat Valve" is a bulk material supply device that contributes to improving the working environment at installation sites due to its high sealing capability, which minimizes the leakage of powder and granules. Additionally, it exhibits stable cutting performance with minimal performance degradation due to pressure. It also features reduced impact on transport pressure during pneumatic transport of bulk materials and has less flushing. With a durable and long-lasting design, it allows for reduced running costs. There are many cases where it has been used for over 30 years, with the longest usage starting in 1982, and an update scheduled for 2025, demonstrating a record of 43 years of use. We also have comparison tables with various quantitative supply devices, which you can use as a reference for your introduction considerations. 【Features】 ■ Outstanding sealing capability and excellent quantitativeness ■ Capable of continuous operation for long periods even with highly abrasive bulk materials ■ Supports small quantity cutting of bulk materials (Slat Valve small quantity cutting type) ■ Air cleaning function suppresses the adhesion of bulk materials inside the casing *For more details, please download the PDF or feel free to contact us.

Presentation of comparison table with rotary valve: Slat valve delivery case 3

Presentation of comparison table with rotary valve: Slat valve delivery case 3

Numerous achievements in building material factories: The air leak amount is very low with only two surfaces, and there is a record of 30 kPa in air transport.

We would like to introduce a case study of the "slat valve" handled by Matsushita Environmental Industry Co., Ltd. for air transport applications. We supplied products for air transport air locks. This product has a flat gap between the upper and lower valve plates and the casing (rotor) that is only on two sides, resulting in very low air leakage, with a proven performance of 30 kPa in air transport. 【Slat Valve Features】 - A shape resembling a vertical rotary valve - The rotor is fixed and does not rotate (does not mix the powder) - The upper and lower valve plates rotate coaxially, allowing powder to enter and a fixed amount to exit *For more details, please download the PDF or feel free to contact us.

Many achievements in steelworks! There are numerous accomplishments as a blast furnace injection fine coal supply system!

We would like to introduce a case of our "Slat Valve," handled by Matsushita Environmental Industry Co., Ltd., delivered to a steel mill. We supplied a high furnace injection fine coal feeding machine (1300A) for the steel mill. This product supplies material through the upper and lower valve plates by the self-weight drop of the powder, and all is discharged from the lower valve plate, resulting in high accuracy. 【Slat Valve Features】 ■ A shape resembling a vertical rotary valve ■ The rotor is fixed and does not rotate (does not mix the powder) ■ The upper and lower valve plates rotate coaxially, allowing powder to enter and be discharged in a controlled manner *For more details, please download the PDF or feel free to contact us.

Rotary Valve Alternative "Slat Valve" Repair Case Examples

Rotary Valve Alternative "Slat Valve" Repair Case Examples

A total of 9 repairs have been made, featuring a highly durable slat valve! It allows for long-term use and offers cost-saving benefits.

We would like to introduce an example of a slat valve conducted by Matsushita Environmental Industry Co., Ltd. We delivered it to the customer in January 1998. Since then, we have performed a total of nine repairs at intervals of about 2 to 3 years, and although there have been several parts replacements, it is still operating without any issues. While we are certainly grateful for new purchases, we are also very happy as a manufacturer that our products are being used carefully and for a long time. *For more details, please download the PDF (pre-repair inspection, post-repair report) or feel free to contact us.

No blow-up! High sealing performance slat valve.

No blow-up! High sealing performance slat valve.

Attention those struggling with powder blow-off from rotary valves!

We delivered one slat valve as an alternative to a customer who was struggling with powder blow-up due to air transport pressure, even with a two-stage rotary valve. They are very pleased, stating that even with just one unit, the sealing performance is excellent, and the blow-up has almost disappeared! *The attached catalog "From Rotary Valve to Slat Valve" contains detailed information before and after the replacement. Please be sure to download it!

Reliable Air Transport: High-performance slat valves with excellent airtightness and durability.

Reliable Air Transport: High-performance slat valves with excellent airtightness and durability.

Achieves excellent bulk material supply functionality with a structure completely different from conventional rotary valves!

This product is a slat valve shaped like a horizontal rotary valve. Instead of supplying powder by rotating blades like a rotary valve, it features plates that rotate coaxially up and down, allowing the powder that enters through the opening of the upper rotating plate to exit through the opening of the lower rotating plate. By providing openings at positions directly opposite each other on the upper and lower rotating plates, it ensures both metering and airtightness. In particular, the airtightness is significantly higher than that of a rotary valve. 【Features】 ■ High sealing performance (minimal powder leakage) ■ Strong in pneumatic transport of powders (especially when air transporting powders to the next process) ■ Long lifespan (some customers have used it for over 40 years while performing repairs) *For more details, please download the PDF or feel free to contact us.
