Ebsray® RV Series Pressure and Flow Modulating (PFM) System Equipment is designed and precision built for applications in pumping systems which demand accurate Constant Pressure Control (CPC) or Flow Modulation/Control. CPC pump systems historically required expensive variable-speed drives, complicated variable displacement pumps and inefficient bypass-type valves. The Ebsray PFM System is a cost-effective alternative that enables constant pressure control from simple input signals with most types and principles of pumps or pumping systems irrespective of changes in viscosity.
Features and Benefits
- Maintains CPC irrespective of product viscosity or viscosity changes
- Infinitely adjustable pressure settings from either local or remote stations - manual, automatic or PLC control
- Control mediums can be pneumatic or hydraulic
- 90° flanged porting arrangement
- Smooth, vibration-free and quiet operation
