Modulating Brass 1.6MPA Heat Control Valve
VB series control valves are fit for building automation system of air
conditioning, cooling ,heating and so on and also for automation
system of such industries as chemical, petroleum, metallurgical,
electricity, light industry and so on. With the various output
signals of gauges and computers, it can adjust temperature,
pressure and humidity and can control the parameters of system
flow, liquid level and so on.
VB3000 series control valves consist of VA3000 series actuators and
DN15-DN50 valve body which are threaded connected with the
actuators.
Features
. ABS plastic shell and cast aluminum holder, which are small in
volume and light in weight, are easy for transport and
installation.
. Adapting AC synchronous hysteresis lag on-off electric motor, the
hysteresis clutch departs the output spindle from the drive part
when reaching the limit point, so as to protect the motor.
. High control precision, fast response velocity, low power
consumption, low noises, accurate actions.
. With valve journey self-adapting function, it is easy to install
and adjust in job location.
. Compatible with multiple control signals, incremental/floating
point signal, voltage signal 0(2)~10VDC or electric current signal
0(4)~20mADC.
. Offer feedback signal of valve phase: feedback resistance 0~2K,voltage signal 0(2)~10VDC or current signal 0(4)~20mADC.
