FAR 1640 straight thermostatic radiator valve
FAR 1640 is a straight chrome-plated thermostatic radiator valve designed for connecting a radiator to a steel pipe. It is available in 3/8″ (DN 10), 1/2″ (DN 15), 3/4″ (DN 20) and 1″ (DN 25) sizes.
It is designed for central heating systems where flow regulation and the installation of a thermostatic or electrothermal actuator are required.
The valve is ready for the installation of a thermostatic head or electrothermal actuator. It features a pre-sealed radiator tailpiece, an HPF seal between the tailpiece and the valve body, and a stainless-steel pin with double O-ring sealing. The chrome-plated finish provides a neat appearance, including in visible radiator installations.
