Sealing materials Gate: VITON Bonnet: VITON Feedth rough Rotary feedthrough / VITON V valve seat side VATLOCK configuration 3-position pneumatic actuator or stepper motor 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 position. The stepper motor/controller version ensures accurate...

Certain options are not available for some nominal diameters or cannot be combined. Moreover, options can affect the general technical data. V valve seat side - 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 50000) - Solenoids for impulse actuation: actual valve position is maintained at power failure - Solenoid separate, for external mounting - Customer...

Gate valve control system Pressure controller Pressure control Position control Local operation Remote operation Logic interface PM-5: Version for local and remote control PM-4: Version for remote control The PM-4 / PM-5 controllers ensure fast and accurate pressure control. The LEARN function, being performed only once during system set-up, automatically determines all relevant system parameters. During pressure control the pressure controller continuously adapts to the process conditions (gas type, gas flow). No parameter inputs are necessary. The PM-4 / PM-5 controllers are provided with...
