Proportional Modulating Valve with 0-10V or 4-20Ma
General
VB series motorized modulating valve made of actuator of force 500N or 1000N with DN20 - DN65 valve body. It widely used in air conditioning, refrigeration, heating and building Auto control system, can adjust the medium flow precision, achieved goal to control temperature, humidity, pressure and energy saving.
Features
Shell adopt ABS and frame are die-casting aluminum, small and light, convenient transport
AC Synchronous Motors, built-in two floating auxiliary switch equip with shut power while in
place to protect motor
High control precision, quick response speed, low power consumption, low noise
Configuration travel self-adaption, easy to install and test
