[Proposal Example] Change of Supplier for Existing Products

[Proposal Example] Change of Supplier for Existing Products

Cost reduction of approximately 7.0 yen per unit, saving 3.5 million yen per year with an annual production of 500,000 units, contributing to stable supply of parts!

We would like to introduce a case that our company proposed. With the increase in demand for water-related components (check valves), production volume is transitioning from 15,000 units per month to 30,000 units per month. However, there was a challenge of supply shortages due to insufficient production capacity. Therefore, we proposed a method of sourcing stainless steel valve-type products that have been manufactured by another company for the past ten years and assembling them in-house. By changing the sourced products to those from an automotive parts manufacturing company, we improved quality and reduced costs. Additionally, we created a simple assembly machine to enable in-house assembly. As a result, we achieved a cost reduction of approximately 7.0 yen per unit, saving 500,000 units annually, which amounts to a reduction of 3.5 million yen per year, contributing to a stable supply of components. *For more details, please refer to the PDF document or feel free to contact us.

Performance comparison of dual plate check valves and swing check valves *Materials available upon request.

A check valve that is very suitable for installation in places where sufficient piping space cannot be secured!

Our Super Check (dual plate check valve) has a very simple product structure, resulting in a much shorter face-to-face length and lighter weight compared to other types of check valves. Therefore, it is very suitable for installation in places where sufficient piping space cannot be secured. This document includes a performance comparison between dual plate check valves and swing check valves. Please download and take a look.

[Delivery Example] Check valve with grooved flange surface.

[Delivery Example] Check valve with grooved flange surface.

Can be used with refrigerant piping flanges! *Materials with examples are currently being provided.

Our company has extensive experience with refrigerants (such as ammonia and fluorocarbons) for manufacturers of refrigeration equipment. In some cases, we receive requests to use refrigerant pipe flanges (JIS B8602) on the opposing flange, and we have numerous examples of responding by machining grooves on the flange surface of check valves. This document includes information on "Refrigerant Pipe Flange Compatibility" and "Case Studies." Please feel free to download and review it. Additionally, we also provide compatibility for flanges used in vacuum devices on vacuum lines for vacuum pumps. *For more details, please refer to the PDF document or feel free to contact us.

Dual Plate Check Valve "Super Check"

Dual Plate Check Valve "Super Check"

Pursuing short delivery times, we can ship as quickly as the next day. With a simple structure, maintenance is easy.

The "Super Check" is a check valve consisting of two semicircular disc-shaped bodies attached to a valve box by a single hinge pin along with a spring (JIS B 0100). When fluid flow occurs, each disc opens fully to the stop pin around the hinge pin. Additionally, when the flow from upstream stops, the discs close due to the spring force and seat on the valve box seat to stop the flow. 【Features】 - Compact dimensions for easy installation and removal in piping - Lightweight, contributing to reduced burden on operators - Simple structure for easy maintenance - A wide variety of material combinations for the valve box, disc, and other parts - Cylindrical valve box design suitable for high pressure structurally *For more details, please refer to the documentation. Feel free to contact us with any inquiries.

Check valve

Check valve

Yuai, a specialty store for piping materials and equipment by professionals in filling machines.

It is widely used in sanitary piping to prevent backflow of fluids. It is also called a check valve or backflow prevention valve, and is installed in piping to prevent backflow of fluids such as water. When the pump starts, the valve opens due to the pressure of the flowing fluid, and when it stops, it naturally closes due to the pressure of the fluid trying to flow back.

[Delivery Example] Special Response for Dual Plate Check Valve

Our skilled team of engineers will carefully manufacture check valves tailored to your specifications, considering the material, size, shape, valve box, and strength of the valve body.

Introduction of special cases for dual plate check valves. A check valve (non-return valve) is a valve installed downstream of pressure-generating devices such as pumps to prevent backflow. The valve body opens due to fluid pressure or flow rate, and closes due to a decrease in pressure or flow rate, preventing backflow through spring torque.
