SRV Series Ductile Cast Iron Intelligent Balance Valve

SRV series intelligent balance valve is integrated with sensors, intelligent actuator and regulation valve. It is applicable to central air conditioning system and heating system. The regulating valve receives the control signals from PLC, DDC and other controllers, compares with the real time values from
local sensors (temperature sensor, pressure sensor, flow sensor, and etc.),and make judgment and adjustment accordingly. Thus it realizes accurate control of the temperature, pressure, flow or energy.
