High quality for intelligent balance of electric two control valve

Product overview

Intelligent balance of electric control valve mainly comprises electric two regulating valve, electric three regulating valve, electric three regulating valve, electric butterfly valve. Adopting the balance structure based on reference of foreign advanced technology, a balance component adopts stainless steel precision casting process of the material was 316L, ensure that the valve long-term stability, in the high differential pressure condition accurately control. Widely used in the city central heating, central air conditioning control and district heating, hot water in the temperature, humidity, flow, pressure and other parameters.
