22mm Automatic Bypass Valve | Angled | Compression Connections

Zone valves closing shouldn't mean your pump is running against a dead end. The 22mm Automatic Bypass Valve in an angled configuration maintains a minimum flow path when controls shut off circuits, keeping the pump protected and system pressure balanced. The visual pressure indicator takes the guesswork out of setting the differential pressure, and the 0.1 to 0.5 bar adjustment range covers most sealed heating system requirements.

Key Features

• 22mm automatic bypass valve with angled design
• 22mm compression connections for straightforward installation
• Maintains adequate flow when zone valves close
• Protects pumps from operating against a closed head
• Adjustable differential pressure range of 0.1 to 0.5 bar
• Visual pressure indicator for easy adjustment
• Flow capacity of up to 5 m³/h (approximately 83 litres/minute)
• Reduces system noise and helps maintain even system pressure
• Maximum working pressure: 10 bar
• Maximum working temperature: 100°C

Typical Applications

Ideal for sealed central heating systems and boiler installations where an automatic bypass is required to maintain circulation. Particularly useful in systems with zone valves or other controls that can restrict or shut off water flow.
