Series 64 Sealing materials Gate: Bonnet: VITON Rotary feedthrough / VITON 1 valve gate 2 ball guidance 3 leaf spring 4 ball pairs 5 detents 6 crank bolt 7 gate seal 8 actuator shaft 9 counter-plate a valve seat side VATLOCK configuration The valve gate acts as a throttling element and varies the conductance of the valve opening. Actuation is performed either with a 3-position pneumatic actuator or with a stepper motor and controller. With the 3-position pneumatic actuator, it is not only possible to move the valve gate to the open and closed position, but also to any preset intermediate...

Certain options are not available for some nominal diameters or cannot be combined. Moreover, options can affect the general technical data. Actuator: - Actuator rotated by 90° / 180° to position 2 or 3 (position 1 is standard): see dimensional drawings on pages 88 and 89 for optimum adaptation - Actuator on B-side (A-side is standard) - Stepper motor for vertical mounting position DN 400 (closing time 15 s, cycles until first service 50 000) - Solenoids for impulse actuation: actual valve position is maintained at power failure - Solenoid separate, for external mounting - Solenoid for 12,...
