Auto Bypass Valve Angle SV11

Auto Bypass Valve Angle SV11

The automatic bypass valve (ABV) is 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.

Detail Description

The automatic bypass valve (ABV) is 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 TRVs or zone valves start to close and the resistance of the systems 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 control of systems fitted with TRVs, by ensuring a constant differential pressure across the radiator.

The ABV 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 in the direction of the arrow marked on the body.

 

Technical Data:

Working Pressure: 10bar max

Working Temperature: 100℃ max

Capacity: 1-5m3/h

Connection: 22mm compression

Range: 0.1-0.5 bar differential Pressure

 

Automatic Bypass valves perform two functions:

. As a boiler bypass as required by the boiler manufacturer.

. As a system bypass to accommodate pump overrun and to alleviate system noise that can be caused by increased pressures when TRVs or zone valves start to close.
