regulating valve electronic S-seat adjust valve

Outline

ZDLP, the ZDLM electronic formula electrically operated single-seat, the sleeve regulating valve, accepts the direct current signal which the regulation meter comes, changes is moved the medium current capacity, causes to be accused the craft parameter to maintain at the given value. Widely applies in the electric power, the metallurgy, the chemical industry, the petroleum, lightly spins, industry sectors the and so on the drugs manufacture, papermaking production automation control.
This series product nominal passes the diameter by 20 to 300mm, the nominal pressure has 1.6, 4.0, 6.4MPa,Accepts the signal is 0 ~ 10mA.DC or 4 ~ 20mA.DC,Application temperature scope by -40~ 450 ℃. Electrically operated single-seat regulating valve is suitable for the differential pressure slightly, the medium viscosity is big or has the pellet impurity situation slightly; The electrically operated sleeve regulating valve is suitable for the differential pressure is big also the spillage big situation
