◆All parts of the valve body are made of low temperature steel，suitable for all common non-flammable refrigerants，including ammonia，fluorine，etc.
◆Adopting butt welding without flanges，so as to reduce the risk of system piping leakage.
◆Adopting advanced stepping motor combination，large torque，wide opening/closing pressure range.
◆Multiple control modes：switch type，analog signal 0-10V，4mA-20mA， PLC bus control
◆New modular design which can be interchanged with manual valves manufactured by our own company to realize high efficiency of instlltion，maintenance and repair.
◆Adopting piston structure，V-shaped valve flap to ensure accurate adjusting ability of cooling system.
◆5 levels outer sealing structure，all adopt imported materials to ensure zero leakage of valve parts.
