Intatec – 22mm Automatic Differential Bypass Valve ABPS402022

Intatec – 22mm Automatic Differential Bypass Valve ABPS402022

These automatic manually adjustable bypass valves (ABV) are suitable for all heating systems up to 10 bar static pressure where a boiler bypass is required or where thermostatic radiator valves (TRV) are installed.

The ABV provides a simple method of ensuring adequate flow through boilers which require a bypass as well as reducing system noise.

In systems fitted with thermostatic radiator valves, the ABV opens automatically as the TRV’s or zone valves start to close and the resistance of the system starts to exceed the preset pressure of the ABV.

Automatic Bypass valves are particularly beneficial in improving the efficiency by bypassing the system when necessary and also improving the efficiency by bypassing the system when necessary and also improving the control of systems fitted with TRV’s, by ensuring a constant differential pressure across the radiators.

Installation:

The Automatic By-Pass valve should be fitted immediately after the pump between the flow and return pipes.

Pipework should be 22mm to accommodate maximum capacity and the flow through the valve must be direction of the arrow marked on the body.

Adjust the valve manually (between 0.1 to 0.5 bar) to suit system settings as per the enclosed instructions.

Specifications:

• Maximum Working Pressure: 10 Bar
• Maximum Working Temperature: 100°C
• Flow Capacity: 1 to 5 m³/h
• Connections: 22mm Compression
