## Long description

Herz STRÖMAX-W angled shut-off valve for potable water with internal Rp thread and nominal diameter DN 20 is intended for isolation and flow control in drinking water installations. The compact angled construction enables space-saving installation in supply lines and fixtures. The valve is designed to ensure reliable shut-off while supporting a minimum flow rate of 1.0 l/s, making it suitable for both residential and light commercial plumbing systems where a durable, angle-mounted shut-off is required.
Advantages
The angled design with internal Rp thread simplifies connection to existing piping and fittings, reducing installation complexity in confined spaces. The DN 20 size offers a balance between flow capacity and compact dimensions. A defined minimum flow rate of 1.0 l/s helps maintain system performance and avoids issues related to extremely low flow conditions. Constructed for potable water use, the valve meets functional requirements for isolation and service tasks without adding unnecessary bulk to the piping layout.
Suitable for
 Residential potable water supply lines and risers
 Commercial small-scale drinking water installations
 Maintenance and repair work requiring reliable isolation of circuits
 Installations with limited space where an angled connection is preferred
Key specifications
 Type: angled shut-off valve for potable water
 Connection: internal Rp threaded connection
 Nominal diameter: DN 20
 Minimum flow rate: 1.0 l/s
 Application: isolation and flow control of drinking water circuits
How to use
Install the valve in the supply line using the internal Rp threaded connection, ensuring compatible thread sealing and correct pipe alignment. Tighten to manufacturer-recommended torque values to secure a leak-tight joint. Use the valve to isolate sections of the potable water system during maintenance or repair; operate the shut-off element fully closed to stop flow and fully open for normal operation. Verify correct flow rate and leak-free installation after mounting, and follow local plumbing codes for commissioning.
Usage recommendations
Prior to installation, flush the pipeline to remove debris, and use appropriate thread sealant compatible with potable water systems. For long-term reliability, operate the valve periodically and inspect for leaks or corrosion. When installing in hard-to-reach positions, allow sufficient clearance for future access and service.
