The Power Genex ATEX EXD SS3R Electro Pneumatic Smart Positioner provides accurate valve positioning for Spring Return and Double acting actuators. The positioner features 4-20mA input, HART Communication, Limit Switches and 4-20mA position transmitter. This positioner confirms to NAMUR standards for easy mounting.

Bettis actuators are pneumatic or rack and pinion devices that automate quarter-turn valves and other rotating mechanisms: 

• Bettis CBB-SeriesA compact, lightweight actuator that's ideal for automating ball, butterfly, and non-lubricated plug valves. It's economical, low maintenance, and available in spring-return and double-acting models.

The Shafer rotary vane actuator was specifically designed for pipeline applications where rugged dependability of equipment is vital. The rotary vane actuators are used to automate ball valves or plug valves in all types of severe climatic conditions.

The Emerson TopWorx PD Series Smart Valve Positioner provides an intelligent, reliable, and versatile solution for valve control with non-contacting sensor technology. This portfolio of compact, intelligent valve control devices communicates with advanced protocols including HART and is capable of being certified for hazardous areas. Smart communication is enabled via a 4-20mA loop signal as well as available open/close discrete inputs. By utilizing contactless internal sensors, the PD Series eliminates wear and reduces costly maintenance. Field calibration and adjustment are simplified with the PD Series LCD interface and the push button or magnetic key controls which enable local control without the need to remove the enclosure cover.

A conductivity sensor is a sensor used to measure the conductivity of various solutions such as ultrapure water, pure water, drinking water, sewage, etc., or the concentration of the overall ion of water samples in the field of laboratory, industrial production, and detection.

Hytork pneumatic actuators are specifically designed to provide valve automation in highly challenging environments. They feature a rugged body made from a high strength LM25 aluminum casting, designed to prevent damage from dents, shock and fatigue.
