HRVW smart electric adjusting butterfly valve

HRVW adjusting butterfly valve is one of HRV smart electric adjusting valve, made up of HRQ smart electric actuator and domestic valve, is an adjusting valve with high performance, widely used in power、metallurgy、petroleum、chemical、pharmacy、boiler、light industry and other automatic control system

Electric actuator receive 4～20mA control signal, change opening of valve, feedback the isolated signal of valve opening to control system, achieve regulation of pressure、temperature、flow、liquid level
