Range of self-acting controllers with brass bodies, EPDM O rings and gaskets. Maximum operating pressure 16.0 bar. Maximum operating temperature of the secondary circuit 65˚C, and the primary circuit is 99˚C.
Preheat accessory assembly for connection to the domestic hot water circuit of a combination boiler. Maximum working pressure 10.0 bar. Maximum operating temperature 85°C.
Permanent filling 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, two solenoid valves operate to allow water into the system via the transfer chamber. At all other times the normally open solenoid valve drains the transfer 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 5.0 Bar. Cold water use only.
Spherical valve with brass body and ball, PTFE seat, EPDM and NBR ‘O’-rings. The valve is intended for installation on the cold water inlet of a combination boiler and incorporates a branch to supply the primary circuit. Maximum working pressure 10.0 Bar. Cold water use only
