Festo Proportional pressure regulator VPPI
The valve VPPI is a directly actuated proportional pressure regulator that uses two proportional 2/2-way valves as a basis. The valve regulates a pneumatic pressure to an electronically defined value. This makes use of cascaded closed-loop control of pressure/motion and current. Control is provided using an analogue current or voltage signal, or alternatively using a digital pattern (voltage version only) for adjustable setpoint values, or using a PWM signal (voltage version only).
Special Features:
- Low-noise
- Flexible
- Highly dynamic up to 30 Hz
- The max. frequency of 30 Hz protects the system
- Available with Bluetooth interface
- Precise and stable: the powerful moving coil actuator also ensures that setpoint value changes are quick, easy and precise
- Lots of pressure ranges
- Pressure regulation range: –0.1 … 1.2 MPa
- PWM operation: the VPPI detects PWM signa
