With legislation moving towards lower and lower emissions, both directly from production gas, but also indirectly from compressed air generation, Bifold have developed the new Pneumatic Intelligent Controller (PICø).
PICø is a true zero bleed pneumatic positioner with a bleed rate 1 Millionth that of existing pneumatic positioners.
By combining some of Bifolds broad range of individual pneumatic control elements, including;
- Patented balanced hard seated solenoid valves
- Patented proportional fill and exhaust filter boosters
- Universal Digital Positional Controller
- And Pressure transmitters
Bifold have developed a revolutionary control system which will transform Pneumatic actuation, both in positional control but also on/off and ESD valves.
The PICø will be available with one control logic head which is then amplified by the Bifold Filter Booster range from ¼" up to 2"
The patented Bifold filter booster technology allows an equivalent flow rate of larger systems to be achieved by the PICø. e.g ½" Filter Booster system, delivers a flow performance of a 1" tubed system.
This exceptional flow is achieved by moving all the pressure regulation and valve control logic away from the flow line, at the same time as combining the filter into the booster itself. This final step results in the maximum possible differential pressure across a single element, maximising flow.
In addition to the positional control capability of the PICø, which is comparable with the industry leading pneumatic positioners, the PICø can be used on on/off and ESD actuators because of its true zero leak capability combined with proportional control and high flow.
The benefits of the PICø on on/off actuators include;
- Efficient use of compressed air, by only pressurising the actuator to open fully and not continuing to fill to a regulator set pressure
- Higher operating pressures resulting in smaller actuators (10 bar working pressure)
- Allowing controlled and accurate partial stroke with diagnostics of safety factors, without the need to vent any actuator over pressure before initiating movement
The Bifold Universal controller, which forms the digital control element of the PICø, is a fully configurable Smart controller with on screen valve diagnostics, signatures and data capture.
The controller features HART, Modbus and Bluetooth comms as well as fully configurable control logic.
Combined with hazardous area certification the PICø is compliant to leading industry control standards including GE/Nouvo Pignone, 34-SAMSS-634 ZV etc.
