Best Positioner?

You can try Fisher products.

The Fisher DVC 6000 series is about the best product on the market. Quite robust and integrates well with most systems, also great diagnostic capabilities.

Hi,

My experience is limited to fisher valve positioners.

Masoneilan is the only other brand I worked with when we installed four masoneilan valves with masoneilan positioners,one out of the four positioners failed when the valve was put in service.

We asked masoneilan for a new positioner but they refused and sent their field technician to fix the positioner that failed, but He ended up replacing the positioner.

As mentioned jm and dabdool ,Fisher DVC fieldvue positioner is a good reliable easy to work with instrument.

Thank you
