The characteristics and applications of the intelligent electric socket pneumatic control valve

Sleeve pneumatic control valve, electronic single seat, and adjusting instruments to dc current signal, change the modulated medium flow, keep accused of process parameters in the given value. Widely used in electric power, metallurgy, chemical, oil, textile, pharmaceutical, paper and other industrial sectors of production automation control. The series of products from 20 to 300 mm nominal diameter, nominal pressure is 1. 6, 4. 0, 6. 4 mpa, accept the signal of 0 ~ 10 ma. DC or 4 ~ 20 ma. DC, use the temperature ranges from - 40℃～450℃。 Electric single-seat pneumatic control valve is suitable for the pressure difference is small, medium viscosity or slightly larger particles impurities occasions; Electric socket pneumatic control valve is suitable for the pressure difference is larger and larger leakage situation.
