Summary of electric butterfly valve.
Electric butterfly valve with electric actuator butterfly valve and the perfect combination of the name, the same need of torsion configuration to conform to the international general SIO5211 connection standard platform and are + 5 ° for fine-tuning, and achieve precise Concorde.
Electric actuator 90 ° 120 ° 180 °, 270 ° rotation Angle stroke type torque feedback control can be divided into passive contact switch/intelligent external regulation, explosion-proof, flameproof special environment. Hard aluminum alloy shell. Built-in overheating protection, control of feedback signal, indicator perspective window, with emergency manual device protection grade IP67 power installation dimension at the bottom of the accords with ISO5211 / DIN3337 international standards to adapt to the environment temperature 8 ℃, epoxy resin coating.
Working power supply usually have: DC24V, AC220V, AC380V, etc. The input signal: 4 ~ 20 ma, 0 ~ 10 v and other weak current signal. By the external regulation electric actuator and the valve stem connection after debugging; With electricity as the driving force to drive the hard seal butterfly valve plate and a 0 ~ 90 ° part of rotary motion. Receives the industrial automation control system of 4 ~ 20 ma signal to precisely control the valve opening, so as to achieve different process parameters such as flow, temperature, pressure regulation and control.
