1″ Brass Non-Return Check Valve – Heavy Duty, Spring-Loaded, Female Thread (1 Inch)

Protect Your Pump with Precision Flow Control

The 1″ Brass Non-Return Valve is an essential plumbing safeguard designed to maintain system pressure and prevent backflow. Engineered for high-performance water systems, this valve allows water to move freely in the direction of the pump while instantly sealing tight if the flow reverses. Whether installed on a borehole delivery line, a booster pump system, or a water tank inlet, this valve eliminates “water hammer” and ensures your pump starts smoothly every time without losing prime.

Key Engineering Features:

• Spring-Loaded Mechanism: Equipped with a high-tension internal spring that ensures a rapid, positive seal even in low-pressure situations, preventing even minor back-leakage.

• Full Flow Design: The internal chamber is optimized to minimize turbulence and friction loss, ensuring your 1″ pump maintains its maximum rated flow rate.

• Corrosion-Resistant Solid Brass: Forged from high-grade brass to withstand the mineral-rich or “hard” water conditions common in many parts of Kenya, preventing the valve from sticking over time.

• NBR Leak-Proof Seal: Features a durable NBR (Nitrile) gasket that provides a bubble-tight seal and is rated for temperatures up to 100°C, making it suitable for both cold and hot water applications.

• Dual-Directional Mounting: Can be installed in both horizontal and vertical positions, providing maximum flexibility for tight plumbing manifolds.
