Overview
Essential details：65040-PACV-AYU2/9049 Pendulum valve control system
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)

65040-PACV-AYU2/9049 Pendulum valve control system
Product Description
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.
