Achieving high maintenance performance with a unit-based design! A diaphragm valve with zero seat leakage due to high airtightness, excellent corrosion and chemical resistance.

This catalog features a variety of diaphragm valves manufactured and sold by Japan Diaphragm Valve Co., Ltd. A diaphragm valve is a type of valve that has a structure that opens and closes the flow path using a flexible diaphragm made of materials such as rubber. They can be broadly classified into two types: the wear-resistant type with high airtightness and the straight type with low pressure loss and minimal liquid accumulation. The catalog includes a diverse range of products, including manual operation valves, air-operated ON-OFF valves, and electric operation valves. Additionally, technical materials such as dimension and material selection tables are included at the end. [Contents] ■ Manual operation valves ■ Air-operated ON-OFF valves ■ Air-operated flow control valves ■ Electric operation valves ■ Technical materials, etc. *For more details, please refer to the PDF materials or feel free to contact us. (The English and Chinese versions of the catalog can be downloaded from the catalog page of the special website below.)

A structure that opens and closes the flow path with a flexible diaphragm! We will introduce two types of valve designs.

The product consists of three units: the drive part, diaphragm, and main body. It controls the fluid by pressing the diaphragm against the sealing part of the inner surface of the main body and then releasing it. The wear-type "Model 400" maintains airtightness by ensuring that the diaphragm and the main body's dam are in close contact without gaps, demonstrating high valve seat sealing performance. The materials for the main body and diaphragm are diverse, allowing compatibility with a wide range of fluids. Additionally, the straight-type "Model 500" features a flow path that is nearly linear, resulting in a structure with minimal pressure loss and liquid pooling, making it suitable for fluids containing viscous fluids, fibrous fluids, slurries, sludge, and suspended solids. 【Features】 ■ No leakage to the outside and no contamination of the fluid from outside air ■ Zero valve seat leakage ■ Simple main body shape suitable for lining processing ■ Minimizes liquid pooling and possesses self-cleaning properties ■ Adopts a three-unit system, making disassembly and assembly easy *For more details, please refer to the PDF materials or feel free to contact us.

A large number of ball valves, including fire-safe types and V-port valves, are featured!!

This document is a product catalog for ball valve products from Japan Diavalve, which manufactures and sells valves. It includes the "Fire Safe Type Ball Valve," which can suppress fluid leakage when sealing parts such as seats and packing are burned in fires, as well as the "High Pressure and Large Diameter Ball Valve," commonly used for general processes and high-pressure sludge, and the "Jacketed Ball Valve," which has a double structure with a jacket on the outside of the main body. You can choose from a rich lineup according to your application. [Contents] ■ 2-Way Ball Valve ■ 3-Way Ball Valve ■ V-Port Valve ■ Pneumatic Operated Valve ■ Electric Operated Valve ■ Special Purpose Ball Valves ■ Handling Precautions *For more details, please refer to the PDF document or feel free to contact us.

Toby Technology Co., Ltd. will be exhibiting at the "Problem-Solving EXPO 2026 Small and Medium Enterprises Tech Fair in Kyushu 2026" held at the Kitakyushu Messe. At our booth (T-04), we will introduce skill inheritance and education using eye tracking (gaze measurement). Eye tracking visualizes the "intuition and tips" of skilled workers, contributing to the reduction of training periods in visual inspections and minimizing the oversight of defective products, as well as subsequent education and evaluation. On the day of the event, we will have a wearable eye tracker (glasses-type gaze measurement device) available for demonstration. Depending on your challenges and interests, we will introduce the optimal ways to utilize this technology, so please feel free to stop by and consult us if you have any questions or concerns. We sincerely look forward to your visit. <Visitor registration here> "Problem-Solving EXPO 2026 Small and Medium Enterprises Tech Fair in Kyushu 2026" https://kyushu-tf.solution-expo.jp/
