MacDonald Plumbing Supplies MacValve 22mm Chrome Plated Angled Auto Bypass Valve

The MacValve 22mm Chrome Plated Angled Auto Bypass Valve is designed to maintain efficient water circulation in central heating systems. It automatically opens to allow flow when thermostatic radiator valves close, preventing pressure build-up and protecting system components. With adjustable pressure settings and a durable chrome-plated finish, it offers reliable and long-lasting performance.

The MacValve 22mm Chrome Plated Angled Auto Bypass Valve is an essential component for ensuring the safe and efficient operation of modern central heating systems. When thermostatic radiator valves (TRVs) close, system pressure can increase and restrict water flow. This automatic bypass valve resolves this by opening to maintain circulation, helping to protect pumps, boilers, and pipework from unnecessary strain.

Manufactured with a high-quality chrome-plated finish, the valve offers excellent durability and resistance to corrosion, making it suitable for long-term use in demanding heating environments. Its angled design allows for flexible installation in various pipework configurations, particularly where space may be limited.

The valve operates effectively at pressures up to 10 bar and temperatures up to 100°C, ensuring compatibility with most domestic and light commercial heating systems. An adjustable bypass setting allows precise control between 0.1 and 0.5 bar, enabling installers to fine-tune performance according to system requirements.

Designed for ease of installation and reliable operation, the MacValve 22mm Chrome Plated Angled Auto Bypass Valve is ideal for improving system efficiency, reducing noise, and prolonging the lifespan of heating components.
