Residential Water Supply Pressure Reducing Valve "Benkei Series RD-44SN Type"

A pressure-reducing valve with a shut-off valve for individual water supply that operates reliably from low differential pressure to high differential pressure.

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.
