ELEGANT installation set, for bathroom radiators, straight or angular. Straight or angular thermostatic valve, straight or angular lockshield valve, PRESTIGE thermostatic head. SF series thermostatic valve (straight and angle) are designed for mounting on central heating radiators on the side of the inlet water. In a set with a thermostatic head they regulate the amount of heating medium flowing into the radiator. By increasing the amount of hot water supplied to the radiator, the valve raises the room temperature, and reducing the amount of water flowing in reduces the temperature. Such regulation allows you to maintain a comfortable room temperature regardless of weather conditions prevailing outside, and at the same time contributes to a significant reduction in heating costs, reducing energy consumption.
