Hyco SF7 Speedflow Expansion Vessel, Check Valve & Pressure Reducing Valve with Fast Install

The Hyco SF7 Speedflow Expansion Vessel, Check Valve & Pressure Reducing Valve with Fast Install is a complete accessory solution designed for Hyco Speedflow unvented water heater installations. Depending on the system configuration, additional accessories such as this unit may be required to ensure compliance with UK water regulations.

This integrated assembly combines an expansion vessel, pressure reducing valve and fast-install inlet group incorporating a check valve. The expansion vessel accommodates pressure increases caused by thermal expansion, while the pressure reducing valve regulates incoming mains pressure to help protect the system.
