Electric Tee confluence, shunt control valve

product drawing

features

    ZYHDH, ZYHDF type electric tee confluence regulator and electronic tee shunt regulator use cylinder window valve core guiding, equipped with DKZ straight travel electric actuators, accept 0-10 or 4-20mADC signal drives valve open and close. Which tee confluence regulator is used for mixing two fluid into a third fluid, or mixing the same fluid of different temperature into one temperature fluid. The shunt valve will divided one fluid into two fluid. Electronic tee confluence and shunt regulator nominal diameter is from 25mm to 330mm, nominal pressure is 1.6, 4.0, 6.4 Mpa, suitable fluid temperature is from -60°-450°, control signal is 0-10 or 4-20mADC, leakage standard is Class IV and VI. Flow characteristic is linear and parabola types. Equipped with different bonnet that are normal type and radiating type. This product performance index implement GN/T4213-92.
