Proportional Modulating stainless steel Valve
VB7000 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.
VB7000 series control valves consist of VA7000 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.
