Deskripsi
Katup Sudut Perunggu JIS F7352 5K SDNR
Yang WDL Valve JIS F7352 5K, katup sudut SDNR berbahan perunggu is designed for marine piping systems requiring both manual shut-off and reverse-flow prevention. SDNR means screw-down non-return, allowing the valve to operate as an isolation valve while also helping prevent backflow when it is open.
The compact 90-degree angle pattern changes the direction of flow through the valve and can reduce the need for a separate pipe elbow in suitable installations.

How the SDNR Valve Works
The handwheel and stem allow the valve to be closed manually for pipeline isolation. When the valve is opened, the disc can respond to the direction of flow. Forward pressure lifts the disc, while reverse flow pushes it toward the seat to help prevent backflow.
This combination makes the JIS F7352 bronze angle SDNR valve suitable for systems where both an isolation valve and a non-return valve would otherwise be required.
