Description
65040-PACV-AYU2 VAT Vakuumventile AG
The plate acts as a throttling element and varies the conductance of the valve
opening. The pressure controller calculates the required plate position to achieve the
setpoint pressure. See also principle drawing on page 280. Actuation is performed
by a stepper motor. An encoder monitors the position. This principle ensures fast and
accurate process pressure control.
For leaktight closing the sealing ring is pressed downwards by a spring. For opening
the sealing ring is lifted pneumatically
Actuator
– Actuator on B2-side (Dia. 1)
– Controller with configurable PID parameters
(adaptive, upstream, downstream, soft-pump)
– RS232 interface with 2 analog outputs
Valve
– Other sizes, e.g. DN 80
– Other flanges, e.g. ASA-LP
– Customer specified flanges,
e.g. rectangular flange for direct mounting to chamber
– Surface treatment, e.g. nickel-plated
– Other sealing materials
– KF ports in body
– Heater with insulation (Pic. 2) for valve temperatures up to 120 °C
(for valve temperatures up to 200 °C on request)
– Valve with detached pressure controller (Pic. 3)
– Valve for pressure control only (no leaktight closing)
– Wedge-shaped plate for smaller controllable conductances
– DN 320: 16 ls-1 (standard 22 ls-1)
– DN 350: 19 ls-1 (standard 25 ls-1)
– DN 400: 22 ls-1 (standard 30 ls-1)

By operating the LEARN function – needs to be done only once at start-up – the
system parameters are automatically determined. Due to the adaptive algorithm the
controller continuously adapts to the process conditions (species of gas, gas flow)
and thus ensures optimum pressure control at any time.
In position control mode the valve plate can be moved to any position. Status and
position are displayed by means of 4 digits.
The valve can be controlled by a computer via Logic, RS232, RS485, DeviceNet®,
Ethernet, Profibus, CC‑Link or EtherCAT interface.
The RS232 interface and the field busses also have digital inputs to close and open
the valve. In addition, digital outputs are available for «open» and/or «closed».
Control via Logic interface performs via digital and analog inputs and outputs.
Control via computer by using the CPA software developed by VAT offers
comfortable functions such as
– Setup
– Operation
– Monitoring
– Diagnostics
– Graphical illustration of the pressure behavior
– Programming and recording of sequences
– Several possibilities for data analysis and process optimization
