The Altecnic range of radiator valves are of durable construction giving dependable performance for building services and domestic applications. Their aesthetic design satisfies the requirements of modern commercial buildings and domestic interiors. Chrome plated bodies with white thermostatic controllers and lockshield covers give an unobtrusive appearance and complements most decors. For more stylistic modern decors valves are available with chrome finish thermostatic controllers and lockshield covers. The inlet connection of the valve body is either compression or push fit for use with copper tube. Supplied with manual cap for stem protection and manual isolation. Altecnic thermostatic radiator valves are BS EN 215 certified. Thermostatic radiator valves are typically used for regulating the flow to radiators of central heating systems. They can also be used with a remote sensor to control the flow to heated ceilings and fancoils. The thermostatic controller contains a liquid filled element which automatically controls the opening of the valve to keep the ambient temperature of the room at the set temperature. This prevents temperature fluctuations in the room and achieves considerable energy savings. The thermostatic controller has a '0' setting which prevents flow but when positive isolation is required the manual cap must be used. The frost setting prevents the radiator and pipework from freezing and causing damage from flooding to floor coverings and structural items. Note: For the frost setting to operate the heating system must be switched on.
