Automatic By-Pass Valve ABV

£8.40 £4.20 + VAT

SKU: ABV Categories: ,


The Automatic By-Pass opens only when the system pressure dictates. This will increase the system efficiency as well as eliminating any system noise. A lot of boiler manufacturers demand that the circulation of water through the boiler heat exchangers should not fall below a certain limit, regardless of system load. The valve will open and close to suit the system. The Automatic By-Pass valve is pressure operated.
