Electric small signle seat, sleeve control valve

product drawing

features

ZYHDP, ZYHDM electric small signle seat control valve and electric small sleeve control valve are the executed units of DKZ type electric unit combination instruments, are one of the important link in production process automatical adjustable system. It is powered by power accept uniform standard signal 4-0-10 or 2mADC, shift it to the corresponding up and down displacement of input signal. Thus they are widely used in chemical, petroleum, metallurgy, power stations and textile and other industrial production process automatic adjustment and remote control. The electric small single seat regulator and electric small sleeve regulator produced by Shanghai Yihuan flow control equipment Co., ltd have standard, bellows sealing type, jacket insulation types, etc. Nominal pressure rating is PN16, 40, 64, Nominal diameter scope is DN20- 400.
