Evolve 22mm Automatic Bypass Valve
An effective automatic bypass valve for use on heating systems. An automatic bypass valves are used to make heating systems more efficient and can benefit systems by helping to reduce persistent water velocity noise.
Building Regulations Requirements
Government approved guidance covering the part of the Building Regulations related to the conservation of energy states that in all systems in which the boiler manufacturer’s instructions demand a bypass, or specify a minimum flow rate through the boiler, that an automatic bypass valve be fitted. This type of valve modulates open when necessary to ensure that the appropriate minimum flow rate is maintained through the boiler, at all other times it is closed thus preventing unnecessary and wasteful circulation through the bypass and the boiler.
In addition to providing to providing boiler minimum flow control, automatic bypass valves can be used to reduce persistent water velocity noise that may occur in some systems.
