Range of booster sets with a stainless steel manifold system connecting 2 or 3 wholesome water pumps (For BOSS 2HELIX & BOSS 3HELIX models only). The set also includes spherical valves, and a non-return valve Maximum working pressure: 10.0 Bar Maximum operating temperature: 40°C
Range of gear or lever operated wafer, semi lugged or fully lugged butterfly valves with blue epoxy coated ductile iron bodies, stainless steel discs and EPDM seats. Maximum working pressure 16.0 bar. Maximum operating temperature 80°C.
Range of expansion vessels with butyl membranes. Maximum working pressure 8.0, 10.0, 16.0 or 20.0 bar (please refer to model). Maximum operating temperature 70 or 100°C (please refer to model).
Permanent filling/ pressurisation device for primary heating and chilled water closed circuits in domestic and non-domestic premises. The mains and closed circuit system pressures are continuously checked by two pressure sensors and their differential monitored by microprocessors. In the event of a fall in system pressure, and only if the mains pressure is adequate, a solenoid valve operates to allow water into the system. At all other times a second solenoid valve drains the fill chamber to waste, via tundish (meeting the requirements of an air gap to drain), and allowing air to be admitted via an automatic air vent to create an atmospheric disconnection across the transfer chamber. Maximum working pressure 6.0 Bar. Cold water use only.
Range of end feed brass fittings for use with copper tube (manufactured to EN 1057). Maximum working pressure 16.0 bar. Maximum operating temperature 85°C.
