Introduction
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.
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.
