The Logix 520MD Series digital positioner combines superior positioning and tuning functions with convenient setup and powerful diagnostic tools. The Logix 520MD positioner uses a multi-variable gain tuning algorithm which allows the positioner to make large step changes with minimal overshoot while achieving the resolution to respond to very small step changes. The Auto-tune procedure cycles the actuator to produce a measured response and selects gain values that provide appropriate actuator performance. The Auto-tune function includes a gain modifier selector that can be used to increase or decrease the calculated gain in order to achieve optimal performance. Easy DIP switch configuration for tuning mode and other common settings. For custom settings, tuning sets can be modified with a handheld or with ValveSight software, to accommodate a wide range of actuator sizes and types.

Ceresist's CER-1200 fine-grain alumina ceramic is next to diamond in hardness and outlasts steel by 12 times and Ni-hard by 5 times. Ceresist wear-resistant products are a long-term, maintenance-free solution in systems that experience rapid degradation due to sliding abrasion, erosion, and impact - even in highly corrosive or high-temperature services.
-
Ceresist ceramic-lined chokes are specified for use in extremely erosive slurries that contain a very high percentage of solids. The large radius entry of the chokes exhibit better consistency and flow recovery characteristics than sharp-edged orifice plates. Furthermore, our ceramic-lined chokes are more compact than venturi-style chokes. The silicon carbide ceramic choke insert is 30 times more wear-resistant than stainless steel, and offers years of maintenance-free service.
-
Ceresist ceramic lined pipe spools are designed to outlast linings such as glass, rubber, basalt, hard facings, coatings, trowelable linings, cure-in-place linings, and plastics that are commonly used to extend the life of piping systems. These materials are only a fraction of the hardness and wear resistance of our ceramics, and in the presence of corrosion or high temperatures, most linings become severely incompatible and their use is extremely limited

The Valtek Mark Four Tek-Check, non-slamming piston check valve, provides rugged performance and reliable service in corrosive and non-corrosive, gas and liquid applications. The smooth, nearly-constant area internal passages allow for high capacity flow with minimum turbulence. When the flow ceases or is reversed, the piston closes slowly, preventing pressure surges. The non-slam design is also effective in dampening pulsating flow.

Noreva's NA is specially designed for gas applications having a centrally guided, single spring with very low fully open velocity. The design is focused on laying the centre of gravity of the only moving part, the disc, over the centre of the surface it is sliding on. Due to this design change, the NA is able to use softer springs, which function at very low flow rates, mainly because the tilting effect of the moving component is eliminated all together. It provides the same internal flow profiles and consequentally, the same pressure loss.
