Brass Spring Check Valve BSP Female Thread

This brass in-line spring check valve is designed to prevent backflow in water systems, helping protect pumps and pipework by maintaining reliable one-way flow. It’s a simple, dependable solution for installations where reverse flow could cause loss of prime, contamination, or reduced efficiency.

Made with a solid brass body and a stainless steel spring, it’s built for long service life in demanding domestic and trade environments. The spring-loaded mechanism closes automatically when flow stops, giving consistent non-return performance without manual operation.

The valve uses BSP female threaded connections, making it straightforward to integrate into many common UK plumbing and irrigation set-ups. Select the correct female thread size to match your existing fittings and pipework.

Suitable for pump lines, garden water systems, and general water transfer applications where backflow prevention is required. Install in-line in the correct flow direction and ensure all threaded joints are sealed appropriately for a leak-free connection.
