Steam reduction takes place via 4 stages. 2 stages are control stages. The 4th stage is integrated in the outlet as a silencer. The perforated basket is designed as the first control stage. The internal control cone is designed as a balanced cone. The design of the cone is a tight-closing shape. The seat is inserted in the body. The sealing inside the body is made by a graphite gasket.
The seat is pressed in via the perforated cylinder, the cover flange, the upper seal and the cover screws. The sealing of the body to the outside is made by a graphite gasket.
The sealing material used in each case is graphite 99.85%. Spindle sealing is done via rings made of graphite. All components can be dismantled with standard tools. Special tools are not required. Welding work is not required. With pneumatic actuator
