Pegler 1/2 Brass Ball Valve
The Pegler 1/2 Ball Valve is a heavy-duty isolation component engineered for high-pressure water systems and industrial fluid control. Built from forged brass with a corrosion-resistant finish, this DN15 fitting provides reliable shut-off performance in residential plumbing, commercial HVAC, and compressed air lines. It features a full-bore design to ensure maximum flow rates without the pressure drops associated with standard-port valves.
Built for the Job
This isolation hardware is a staple for site supervisors and plumbers managing potable water installations or heating circuits. The robust construction handles the thermal expansion and contraction common in hot water return lines. Because it utilizes a quarter-turn operation, technicians can quickly isolate sections of a manifold or branch line during emergency repairs or routine maintenance. The internal ball is precision-machined to prevent sticking even after long periods of inactivity in hard water environments. This component integrates seamlessly into systems using copper, carbon steel, or galvanized iron piping when paired with standard BSP adapters.
-
Main water meter isolation and secondary shut-off points in multi-unit dwellings.
-
Industrial air compressor lines requiring reliable pressure containment.
-
Control points for pump sets and water storage tank inlet assemblies.
Product Highlights

On-Site & Workshop Notes
-
Ensure the use of high-quality PTFE tape or thread sealant on the male threads to achieve a watertight seal without over-torquing.
-
Always use a backup wrench on the valve body hex flats when tightening the pipe to prevent internal misalignment of the seals.
-
This fitting is rated for bi-directional flow, allowing installation in any orientation required by the site layout.
-
Regularly cycle the lever every six months in high-mineral water areas to prevent calcium buildup on the ball surface.
