Regulating valve VF

for hot waterfor cold waterflange

Ductile iron motorized control valves of VF730/750 and NL800/870 series apply to HVAC and building automation systems. Once the motorized control valves receive signals transmitted by computers or other devices, they can then adjust temperature, pressure and control system parameters such as flow rate and liquid level. The valves are mainly used to convey mediums such as cold water, hot water, and ethylene glycol solution. Product Features Adopt the AC synchronous hysteresis clutch motor. When the limited position is reached, the hysteresis clutch disengages the motor's output shaft from the transmission part to protect the motor. High-precision control offers precise actions. Low power consumption and low noise. Have the self-adaptive valve travel function. Multiple signal controls: Increment/floating-point signal, voltage 0 - 10 V, current 4 - 20 mA. ABS shell and die-cast aluminum bracket with the advantages of small size and light weight. Easy installation and maintenance.
