【Useful Information】What are valves and fittings?

It is a valve with excellent "air tightness" and "maintainability."

A diaphragm valve that controls fluid by lifting the diaphragm at the drive part or pressing it against the valve seat, features excellent sealing properties due to the elasticity of the diaphragm. Additionally, it has no pockets in the fluid passage and is streamlined, allowing for easy maintenance by simply removing the bolts and nuts that secure the body and drive part to replace the diaphragm. This diaphragm valve is widely used in various fields requiring sanitary conditions, such as pharmaceuticals, food, and chemicals.

It is a valve that is widely used for adjusting the "flow."

A needle valve is a type of globe valve that excels in shut-off performance and ease of flow adjustment by pressing the valve body against the valve seat to control the flow. It is designed with a needle-shaped valve body to allow for precise flow adjustments. Needle valves, which are specialized for flow regulation, are used in applications across various industries to control "flow."

It is a valve that plays a wide-ranging role in fields that must not leak.

This is a so-called packless type valve that uses a metal bellows for the external seal, which completely prevents fluid leakage by using a bellows, diaphragm, or other methods instead of a gland packing. It is suitable for hazardous, flammable gases, vapors, heat transfer fluids, and vacuum lines. The bellows valve, applicable from high pressure to vacuum and high temperature to ultra-low temperature, is used in a wide range of "leak-free areas" such as nuclear power, thermal power, semiconductors, chemicals, and vacuum applications.

This valve is ideal for use with high-purity fluids in high airtightness and high durability applications.

This is a so-called packless valve that uses a metal diaphragm for the external seal (a sealing method in the gland section that completely prevents fluid leakage by using a bellows or diaphragm instead of a gland packing or other methods). In addition to the high airtightness characteristic of conventional packless valves, it also offers high durability and is free of dead space, making it an ideal valve for use with high-purity fluids.

It is a valve with low fluid resistance and excellent operability.

A valve that controls fluid by rotating a spherical, hemispherical, or cylindrical valve body, allowing for full bore capability with a flow path that matches the inner diameter of the piping. Additionally, there are no obstacles in the fluid within the valve diameter, making it less likely for vortices or pulsations to occur, resulting in excellent flow characteristics. The simple structure and superior operability of ball valves make them widely used in various fields and applications.

Happy New Year! Thank you very much for your exceptional support over the past year. Yoshikawa Co., Ltd.'s Realization Division will continue to contribute to solving your challenges this year as a "Realization House" that transforms your thoughts of "I want to do this" and "Is it possible to do something like this?" into reality, utilizing our skilled stainless steel processing technology. We are pleased to announce that we will be exhibiting for the first time at "The 40th NEPCON Japan," which will be held at Tokyo Big Sight from **January 21 (Wednesday) to 23 (Friday), 2026**, to introduce our technologies and products in greater depth. At our booth, we will showcase a variety of slide-type metal mask dedicated shelves that contribute to improving productivity in the electronics field. These not only lead to efficient management and improved workability in limited spaces but can also be customized according to your needs. We invite you to visit our booth at Tokyo Big Sight during this opportunity. We welcome inquiries such as "Can this processing be done?" and look forward to seeing you there.

From March 24 (Tuesday) to March 27 (Friday), 2026, RheaVita will exhibit as a conference sponsor at ISLFD, held in Fukuoka, in collaboration with Lifix Analytical. ISLFD is an international conference where researchers and engineers involved in freeze-drying and related technologies gather from around the world to exchange information and discuss research results and technological trends. Through our sponsorship at this conference, RheaVita will present the latest information on spin freeze-drying technology. At our booth, in addition to introducing the latest information about spin freeze-dryers, we will be open to consultations on a wide range of topics, including research and development, feasibility testing, scaling up, and comparisons with existing processes. We aim to create a valuable platform for information exchange for those asking questions such as "What is spin freeze-drying?", "What are the differences from conventional freeze-drying processes?", "What are the challenges of scaling up and reproducibility?", and "What new formulation and manufacturing approaches should be considered?". Additionally, individual meetings will be possible during the conference. If you contact us in advance, we will secure a meeting opportunity at a time that is convenient for you. Please be sure to stop by the RheaVita booth.
