Volume Booster PE5000
PE 5000 / PE 5000 S
Operating Principles
The PE 5000/PE 5000S is a pneumatic device capable of high flow and exhaust capacity. This device uses a force balance system to control the movement of the supply and exhaust valves
At set point, the force due to siganl pressure that acts on the top of the Upper Diaphragm balances with the force due to output pressure acting on the bottom of the Lower Diaphragm
Features
- The PE 5000/PE5000 S Pneumatic High Capacity Volume Booster uses a pneumatic input signal to accurately control output pressure
- A balanced Supply Valve minimizes the effects of supply pressure variation
- Aspirator Tube compensates downstream pressure droop under flowing conditions
- Optional Adjustable By-Pass Needle Valve option includes bubble tight exhaust valve allows tuning for optimum dynamic response (1:1 ratio only) and cycle free operation with valve positioners
- Optional Fixed Negative Bias for pneumatic signal devices that cannot be adjusted to zero signal pressure
- A separate Control Chamber isolates the diaphragm from the main flow to eliminate hunting and buzzing
