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.

Exhibits high airtightness and valve seat sealing performance! Excellent in corrosion resistance, chemical resistance, and cleanability.

A diaphragm valve is a type of valve that has a structure for opening and closing a flow path using a flexible diaphragm (membrane) made of materials such as rubber. The "Wear Type Diaphragm Valve: 400 Series" is the basic form of a diaphragm valve that has a weir in the flow path. The fluid passage section is streamlined and has no pocket areas, which minimizes liquid accumulation and provides self-cleaning properties. Due to the valve's structure, it exhibits high airtightness and seat sealing performance. There is a wide variety of materials available for the body and diaphragm, allowing compatibility with a broad range of fluids. ▼Applicable Fields: Chemicals, Environmental & Water Treatment, Steel, Shipbuilding, Pharmaceuticals, Food, Semiconductors, Power Generation, etc. *For more details, please refer to the catalog (P6-P14) or feel free to contact us.

Japan is one of the top 10 countries in the world with frequent earthquakes. The 2020 White Paper on Land, Infrastructure, Transport and Tourism has also reported an increase in the probability of major earthquakes occurring. Regarding the Nankai Trough earthquake, the probability of an earthquake with a magnitude of 8 to 9 occurring within the next 30 years is estimated to be 70 to 80%. At Hotron, we recommend the introduction of seismic devices for earthquake countermeasures in buildings and equipment. The seismic device 'HK-2' is a product that automatically performs various controls that have been pre-set when it detects strong shaking equivalent to a seismic intensity of 5 lower or higher. For example, it can automatically execute actions such as: "Open automatic doors and gates to secure evacuation routes and access for emergency vehicles" "Transmit signals to the control room and stop facility equipment" "Unlock the keys to locked lockers" "Automatically play voice guidance" For more details, please download the materials or contact us.

Do you have any concerns or requests regarding wired bed exit sensors? × Tangling or tripping over wired cables × Cable disconnection or damage × Worrying about forgetting to turn the switch back on after temporarily stopping the sensor. × Wanting to be notified of bed exits even from a location far from the nurse call outlet. Such concerns can be resolved simply by connecting our wireless nurse call linked set to the sensor! Our wireless nurse call linked set allows you to connect bed exit sensors like "Ugo-kun," "Foldable Thin Matta-kun," "Ayumi-chan," and "Just Place Pole-kun" to transmitters and receivers, reducing wiring around the bed area, alleviating concerns about tripping or falling due to cables, and contributing to a tidier work environment. Furthermore, it enables the use of bed exit sensors even from locations far from the nurse call outlet, allowing for more flexible equipment placement.

Kort Valuta has released a workplace initiative model that leverages points exchangeable for electronic money to support the adoption of safety and wellness habits. Examples include: ・Hydration reporting ・Viewing heatstroke prevention content ・Pre-shift condition checks ・Voice-based condition checks By linking these activities to incentive points, organizations can encourage voluntary participation while supporting workplace safety and employee well-being. The model is designed not only for frontline environments such as: ・Logistics ・Construction ・Manufacturing but also for office-based health and well-being programs. Safety posters and reminders alone are often not enough to drive lasting behavioral change. We hope this initiative provides a practical example for organizations seeking new approaches to workplace safety and employee engagement.

[To the owners of parking lots and parking lot construction companies] "I'm worried about not colliding with pedestrians when exiting the parking lot..." Among vehicle entrances to parking lots, stores, residences, and factories, particularly at entrances facing sidewalks or roadways, there is a risk of dangerous incidents such as collisions with pedestrians or between vehicles. To alleviate such concerns, Hotron proposes a [Vehicle Exit Warning Sensor] that detects vehicle departures using various sensors and alerts the surrounding area with LED lights and buzzers. The system consists of a simple configuration of "sensor" + "controller" + "switching power supply (24V)" + "LED rotating light." *Please note that a separate control panel is required to include the controller and switching power supply (24V) when using the exit warning system. *We kindly ask customers to arrange for the switching power supply (24V), LED rotating light, control panel, circuit breakers, etc. Since it can be retrofitted, it can also be used for existing parking lot entrances. We hope this will contribute to safer vehicle passage for everyone. ◎ For more details, please contact us or download the catalog.
