Brass threaded motorized control valves of ES100/ES150 and BL220/BL350 series apply to HVAC (heating, ventilation, and air conditioning), 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
Have the equal percentage flow and the quick opening characteristics.
The control valve's body has a built-in distribution plate that helps the flow control performance more stable.
High-precision control offers precise actions.
Low power consumption and low noise.
Double O-shaped sealing design.
Multiple signal controls: 2-point, 3-point, DC 0-10 V, and DC 4-20 mA.
ABS shell with the advantages of small size and light weight.
Easy installation and maintenance.
