Reliability

• Linkage‐Less Non‐Contact Position Feedback — The

high performance, linkage-less feedback system, shown

in Figure 1. eliminates physical contact between the valve

stem and the instrument. There is no wearing of parts

so cycle life is maximized. Additionally, the elimination

of levers and linkages reduces the number of mounting

parts and mounting complexity. Instrument replacement

and maintenance is simplified because the feedback

parts stay connected to the actuator stem.

• Built to Survive — The DVC7K’s field-proven conformal

coated electronics resist the effects of vibration,

temperature and corrosive atmospheres per the

ISA.75.13 standard. A weather‐tight housing construction

protects the wiring terminal box and critical components

from harsh environmental conditions.

• Eliminate Solenoids  — DVC7Ks in the On/Off

Application Mode provide a more reliable solution over

traditional solenoid valves. They also provide diagnostic

alerts to support early identification of problems
