The "Benkei Series RD-44SN Type" is a pressure-reducing valve with a shut-off valve for individual water supply, installed within the pipe shafts of hotels and apartment buildings. It is designed to maintain a constant water supply pressure despite variations caused by the height differences in mid- to high-rise buildings. Thanks to the test gag method, it is possible to conduct water pressure tests even after installation of the pressure-reducing valve. Additionally, the shut-off valve is separable, which improves workability and allows for easy replacement of the pressure-reducing valve or maintenance of water supply equipment after piping. 【Specifications】 ■ Nominal diameter: 20 ■ Applicable fluid: Tap water, hot water ■ Fluid temperature: 5–90℃ (for pipe end core use: 5–40℃) ■ Applicable pressure on the primary side: 1.0MPa or less ■ Set pressure (adjustable pressure range) ・ RD-44SN Type L: 0.08MPa (0.05–0.12MPa) ・ RD-44SN Type M: 0.2MPa (0.11–0.23MPa) ・ RD-44SN Type H: 0.25MPa (0.2–0.3MPa) *For more details, please download the PDF or feel free to contact us.

The "JRG6320N model" is a temperature control valve designed for installation in a natural refrigerant CO2 heat pump water heating system with instant hot water circulation. It continuously detects the circulating water temperature using a built-in thermostat, thereby stabilizing the hot water temperature. Temperature adjustment is easily possible with the scale ring. Additionally, it comes with an insulation case, making it suitable for energy-saving measures. 【Specifications】 ■ Nominal diameter: 20 ■ Applicable fluid: Hot water ■ Standard setting temperature: 57℃ (at shipment) ■ Setting temperature range: 36～63℃ ■ Fluid temperature (MAX): 70℃ ■ Applicable pressure: 1.0MPa or less ■ Applicable maximum differential pressure: 0.2MPa *For more details, please download the PDF or feel free to contact us.

The "VD-7N type" has a function that automatically introduces air into the negative pressure section to prevent the reverse siphon effect in the water supply system. It is a vacuum breaker used in piping sections where water pressure is always applied but reverse pressure does not occur. It incorporates a check valve and introduces air from the intake valve to reliably prevent backflow. Additionally, it comes standard with a test cock, allowing for functional checks of the check valve and intake valve while connected to the piping. 【Features】 ■ Air intake structure using a float design ■ Check mechanism employing a spring system that closes the valve before backflow occurs ■ Usable indoors ■ Function checks can be performed *For more details, please download the PDF or feel free to contact us.

The ADB-20 type/ADB-20F type is a bypass steam trap that compactly integrates three functions: a thermodynamic trap function, a bypass circuit, and a stop valve. The integrated "trap + stop + bypass" functions can be easily switched with just one tool. Additionally, a test valve can be directly attached to the drain plug section (Rc1/2), allowing for operational checks and use as a drain. 【Features】 ■ A single unit with three functions: bypass steam trap ■ Easy switching between trap, stop, and bypass functions ■ Strong structure resistant to steam hammer ■ Operates reliably without being affected by drain temperature *For more details, please download the PDF or feel free to contact us.

The "ADB-21 type/ADB-21F type" is a bypass steam trap that has been compacted by approximately 38% in terms of spacing and has reduced its weight by about 40% compared to conventional models, making it suitable for assembly in equipment with limited space. The main body and key components (disk, valve seat), as well as other parts (excluding bimetal and sealing parts), are made of stainless steel, providing excellent durability and corrosion resistance. Additionally, the trap + bypass + stop function is integrated and can be easily switched with just one tool. An option with a switching lever is also available. 【Features】 ■ Three functions in one unit ■ Prevention of air blockage ■ Long lifespan due to stainless steel construction ■ Effective use of space and reduction of equipment costs ■ Flexible installation for vertical and horizontal piping *For more details, please download the PDF or feel free to contact us.

The "AD-19 type/AD-19F type" is a steam trap that can be easily disassembled due to its bolt fastening, allowing for the replacement of essential components without removing it from the piping. During the initial phase, the bimetal contracts and is positioned upward, forcing the disk to lift and preventing valve closure issues (air lock). This allows for the rapid discharge of air and low-temperature condensate, preventing air-related problems. 【Features】 ■ Bolt type allows for essential component replacement while still piped ■ Applicable pressure MAX. 1.6MPa ■ Built-in strainer (80 mesh) ■ Essential components made of stainless steel ■ Freeze-proof valve can be incorporated (optional) *For more details, please download the PDF or feel free to contact us.

The "Emergency Shut-off Valve EIM Type Series" is an emergency shut-off valve for earthquake disaster measures that can mechanically detect seismic activity and close the valve. It does not require external power sources such as electrical signals, and can shut off fluid solely using the power generated by seismic motion, making it energy-efficient and cost-effective, while also ensuring reliable operation during power outages. Depending on the application, there are two types of valve designs: butterfly valves and ball valves, with a wide range of outer diameters available. They can be used in various scales of equipment. 【Features】 - No external power required, ensuring energy efficiency and cost savings, with reliable operation during power outages. - Can be installed in locations with explosion risks as there are no heat or ignition sources. - Manual reset operation for the shut-off valve ensures safety and security. - Easy daily inspections can be performed simply by operating the seismic sensor knob to confirm operation. *For more details, please refer to the catalog or feel free to contact us.
