HVP11 Intelligent valve positioner is a necessary accessory for intelligent
pneumatic actuator. Its operating principle is completely different from analog
positioner.
HVP Intelligent
valve positioner and pneumatic actuator construct a feedback control loop, in
this return circuit, the valve position feedback signal is regarded as a
variable
comparing with
given signal in microprocessor and the D-value between them sends out different
length of pulse through the outlet of the main control panel to control the output
pressure of the I/P conversion unit, thereby the control valve is driven to
act.
HVP11 Intrinsically-safety type,HVP12 Explosion-proof type.
FEATURES:
1. High accuracy
to class 0.5;
2. Set and select
output characteristics at will;
3. Low power and air
consumption, high vibration resistance and it is suitable for bad environment;
4. It can match up
with any actuators with different size automatically;
5. Remote
configuration and monitoring can be available with superior computer or hand
terminal end;
6. Self-diagnosis
function for signals outrange, input signal interruption and valve position
signal interruption.;
7. Failure mode：Full open, full close, holding and switch to hand
movement;
8.
Communication with HART
and PROFIBUS-PA protocol;
9. Current
feedback function: output 4～20mA valve position signal.
