ZDR-35002 series electric eccentric rotary valve consists of 35002 series eccentric rotary valve and 3610R series electric actuator components.

ZDR-35002 series electric eccentric rotary valve Product Features

Without reprovision servo amplifier , the access signal , power supply to work .

It has broken down and the letter indicates .

When you can easily select the letter off valve position self-locking , fully open or fully closed .

Can be easily converted electric start , power off works.

It can easily select the input signal 4 ~ 20mA.DC or 1 ~ 5V.DC.

Good seal.

Large flow coefficient can be obtained .

Suitable for a wide temperature range .

Jane valve flow path for viscosity and particle media.

Small size, light weight, good job stability .

ZDR-35002 series electric eccentric rotary valve structure principle

The electronic control 3610R series compared the 4-20mA input signal with the opening signal from the potentiometer to amplified to the direction of the drive to eliminate the difference to control a reversible motor , reversible rotation of the motor output shaft of the moving lower , bias potentiometer until opening signal and the input signal reaches zero , the reversible motor stops rotating . Using this principle to control the opening of the eccentric valve control is adjusted to achieve the purpose of the media .

Eccentric rotary valve with the usual plunger valves, butterfly valves, ball valves different, it is in a straight valve body with a spherical valve body , the center line of the spool shaft centerline of the spherical surface deviation , when the shaft is rotated , then packed in spherical spool on the shaft relative to the seat for the cam-shaped eccentric rotation , and rely on elastic deformation of the flexible arm spool , the spool spherical seat sealing surface in close contact , to achieve a reliable seal.
