KFPV050 Series
proportional-control
valves are for stepless
variable control of gases
and liquids. They feature
a direct-acting, two-port
plunger with a brass or stainless-steel body. The solenoid can turn
360° and the elbow electrical
terminal positioned in 90° increments for maximum wiring
versatility. The valves are used
with the KFPC1 Controller. It
accepts 4-to-20-mA or 0-to-10-V inputs and delivers repeatability and
response accuracy of ≤ 2% F.S., and a
hysteresis of ≤ 5% F.S. Ramp response
time can be adjusted from 0 to 10 sec
to compensate for large fluctuations in
the input signal. Other features include
a zero point switch-off function
ensuring all valves completely close,
LED indicators, and a temperature-compensation circuit.
