PTFE spindle valve with sloped outlet. The spindle shall be pressed in without turning. In the valve housing is an additional spring mounted in. So the spring pressure of the spindle to the valve seat can be increased spring- loaded and the spindle regulates itself. This guarantees a good tightness at large variations of temperature. The industrial valve is available with a 10 mm bore hole (standard) and as desired with a 20 mm bore hole.
