Aqualine CVI-050LF Brass Spring Check Valve 0.5 in

Product Description

The AQUALINE CVI-050LF is a 0.5-inch threaded brass spring check valve designed to allow one-directional flow and prevent backflow in fluid systems. The spring-loaded disc closes automatically when flow stops or reverses, protecting pumps, water heaters, and piping from reverse-flow contamination or pressure surges. Constructed from brass, this valve suits potable water and general plumbing applications. It is typically installed by licensed plumbers in residential and light commercial systems where backflow prevention is required at a connection point.

This check valve is suited for installation in plumbing supply lines, water treatment systems, and HVAC hydronic circuits where 0.5-inch threaded connections are present. The threaded end connections allow straightforward integration into standard NPT piping assemblies without special tooling. It is appropriate for residential and light commercial installations requiring compact, inline backflow prevention.

Key Features

• Spring-loaded mechanism closes automatically to prevent reverse flow
• Brass body construction for corrosion resistance in potable water and plumbing service
• 0.5-inch threaded connections for direct integration into standard NPT piping
• Compact inline design fits tight installation spaces
• LF designation indicates low-lead formulation suitable for potable water systems

Compatibility

Designed as an OEM-style replacement or new-installation check valve for 0.5-inch threaded plumbing and hydronic piping systems.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off the water supply and relieve system pressure before removing or installing the valve. Verify flow direction markings on the valve body and install accordingly, as reverse installation will block normal flow. Use thread sealant tape or compound on NPT threads and tighten to hand-tight plus additional turns per fitting manufacturer guidance — do not over-tighten brass fittings.
