Outback CV0025 25mm 304ss Spring Check Non-Return Valve

The Outback CV0025 Spring Check Valve is a 25mm non-return valve manufactured from 304 stainless steel, designed to prevent backflow in bore, transfer, and pressure pump systems. By allowing water to flow in one direction only, it protects pumps, controllers, and pipework from reverse flow, pressure loss, and unnecessary cycling.
In solar pump installations, maintaining prime and preventing reverse flow is critical for reliable performance. The CV0025 ensures stable system pressure, reduced wear on pump components, and improved overall efficiency — especially in vertical lift and tank-fill applications.
Without a check valve, water can drain back down the line when the pump stops, causing pressure drop, air ingress, and repeated pump cycling. Over time, this leads to reduced pump life and inconsistent system operation.
A spring-loaded check valve provides fast, positive shut-off, ensuring water remains in the line and the system is ready to restart efficiently.
