PMW D3 positioner, supplied by Flowserve, is the most intelligent digital positioners among PMW D-series; however, it is extremely easy to use. This type of positioner can be locally adjusted to fit both single and double acting pneumatic actuators. D3 type features a zero bleed pneumatic relay reducing the air consumption which results in less operational (electricity) cost.
D3 series can offer wireless communication lowering the amount of wiring while eliminating wire damaging and preventing connectors from corrosion in the plant. D3 wireless utilizes dual backbone routers to deliver extra radio paths as a safety feature and can be configured by the user when the signal or power is lost. D3 model has different versions for explosion proof, fail freeze, intrinsically safe, remote mounted and version for SIL2 requirements.
