The butterfly valve of this series adopts the principle of three-dimensional eccentricity, which makes the space movement track of the sealing surface idealized. There is no friction between the sealing surfaces, no interference, and the sealing material is properly selected, so that the sealing and corrosion resistance of the butterfly valve are High temperature resistance and wear resistance are reliably guaranteed. Its main features are as follows:
1. The opening torque is small, flexible and convenient, saving energy and energy.
2, three-dimensional braided structure, so that the butterfly plate is tighter and tighter, its sealing performance is reliable, and no leakage.
3, high pressure, corrosion resistance, wear resistance, long service life, etc.

Executive agency
The 3610R series electric actuator is an all-electric actuator that accepts DC4~20mA, DC0~10mA or DC1~5V control signals from DCS, PLC system or regulating instrument operator with AC220 single-phase AC power supply as the driving power source. The actuator has functions such as a motion switching function, an opening signal function, and a manual function. Large-diameter butterfly valves generally use 380VAC electric actuators, domestic brands such as Shanghai Aotoke, Yangzhou Power, Tianjin Ertong, etc.; foreign brands include British Rotork, France Bernard, Germany West Boss (Siemens) and so on.
