Starting from July 2025, we will begin accepting orders for our new product series, the "EX-Bioclean Diaphragm Valve." This product is a next-generation diaphragm valve developed from our existing "Bioclean Diaphragm Valve" series, which is designed for pharmaceutical and related facilities, featuring a new sealing structure. While maximizing the characteristics of the diaphragm valve, such as "a structure that does not contaminate fluids" and "excellent cleanability," we have revamped the sealing structure to better meet user needs and further enhance product performance. 【Main Features】 ■ Currently available on the product page below! *For more details, please refer to the catalog or feel free to contact us.

As a representative of corrosive fluids, there are chemical agents such as acids and alkalis. Additionally, even fluids that typically do not exhibit corrosiveness, such as seawater, can cause damage to materials (i.e., sanitary piping) with prolonged use. The solution developed to prevent damage to these materials (i.e., sanitary piping) is the "corrosion-resistant valve with clamp connection," which features a body lined with fluororesin (ETFE). 【Main Features】 ■ More information is available on the product page below! 【Product Page】 ■ [Sanitary-related Valves] Corrosion-resistant Valve with Clamp Connection *For more details, please refer to the materials or catalog, or feel free to contact us.

We would like to introduce our "2 products" of the 3-way ball valve! The 3-way ball valve (E300 type) is used for switching, diverting, and mixing flow in three directions. There are two main types of flow structures for the 3-way valve: "L-port" and "T-port." For more details, please refer to the links in the "Related Products" section below or feel free to contact us. 【Lineup】 ■E300NB-L2 type: 3-way ball valve L-port with 2 face seats ■E300NB-T4/L4 type: 3-way ball valve T/L-port with 4 face seats

We have published the product page for the 2-way ball valve "F100NB type" <Fire Safe Type>. The Fire Safe Type is a ball valve designed to prevent significant fluid leakage in the event that sealing parts such as sheets or gaskets are burned away due to a fire. 【Main Features】 ■ Available on the product page below! *For more details, please refer to the catalog or feel free to contact us.

We would like to introduce our "2 products" of butterfly valves! The stainless steel high-performance butterfly valve "KM200" is designed to accommodate a wide range of fluids with its reinforced PTFE seat. The drive shaft of the disc is double-eccentric, ensuring that the disc and seat remain non-contact until just before fully closed, resulting in minimal wear on the seat and a long lifespan. The cast iron butterfly valve "C201R" features a concentric contact surface on the seat, creating a self-sealing mechanism that generates contact pressure on the sealing surface of the disc due to fluid pressure, allowing for effective sealing from vacuum to high pressure. For more details, please refer to the related products and catalog, or feel free to contact us. 【Product Lineup】 ■ KM200: Stainless steel high-performance butterfly valve ■ C201R: Cast iron butterfly valve *For more details, please refer to the related products and catalog, or feel free to contact us.
