SK300X Slow-Closing Check Valve

The SK300X Slow‑Closing Check Valve is an intelligent valve installed at the pump outlet of high‑rise building water supply systems and other water‑supply systems to prevent media backflow, water hammer, and hydraulic surge. This valve integrates three functions—electric valve, check valve, and water‑hammer arrester—significantly enhancing the safety and reliability of the water supply system. It employs an integrated technology of slow opening, fast closing, and slow closing to effectively eliminate water‑hammer shock during pump start‑up and shutdown. Simply by operating the pump motor start/stop button, the valve automatically opens and closes in accordance with pump operating procedures, offering large flow capacity and low pressure loss.

Product Features：

● Streamlined body design with low flow resistance**: Small static‑pressure rise ensures stable downstream pressure, effectively protects pipeline facilities, reduces maintenance frequency, and safeguards water‑supply safety.

● Compact structure and small size**: Occupies minimal installation space, facilitating layout in confined areas.

● Wide pressure‑regulation range and stable performance**: Capable of adjusting both dynamic pressure and static pressure, reducing the need for secondary pressure adjustments during pump stop/start cycles.

● Cleaning‑free valve body design**: Reduces the frequency of water‑shutdown maintenance and improves system operational continuity.
