Flat sealing externally threaded tailpipe, 2-fold
DN 20, R ¾, 2-fold, for external thread, for products with union nuts and sealing rings

The three-way conversion valves are suitable for one pipe heating systems with forced circulation and are often used in housing construction in the new Federal states. The body is made of nickel plated bronze/brass. The valve insert is made of brass and the spindle and spring of stainless steel. The valve disc has a soft seal. The pipe connections are designed with flat-sealing external thread. When the valve closes, the flow through the radiator is reduced and the flow through the bypass is increased and vice versa. The three-way conversion valves are supplied with a plastic protection cap, which serves as protection and for manual operation during the construction period. The subsequent temperature control is carried out by a thermostat. All thermostats with connection thread M 30 x 1.5 can be used.
