SYYD series hydraulic actuator

◎ Technical data

1、Liquid supply pressure: 1.0～6.3MPa
2、turn angle: 90±5°
3、Input signal: electro-signal 0～10mA  4～20mA
4、Receptor Voltage: AC220、DC24V
5、Liquid supply connection: M16×1.5、M18×1.5
6、Operation environment temperature: -20～90℃,special -45～120℃

◎ Features

1、Simple structure, compact design, small volume
2、Steady and reliable rotation, with buffer and no clash phenomenon.
3、Use different hydraulic oil as require, operate at the rang of -45℃～
     +120℃, explosion-proof.
4、Would gain large output moment, suit to any specification
5、Output moment can be preciously adjusted by constant pressure and
     flooding valve, including open and close moment adjustment and can
      even be reflected directly by hydraulic instrument.
6、Convenient speed adjustment.
7、When motility halted by accident, can still use accumulator to dynamic
      operation once or several times.
      This has special significance for long-distance delivery pipe and autom
     atic urgent cutting valve and import blowing valve.

◎ Structure

YD series hydraulic actuator is a new developed rotation type of hydraulic actuator. Its two piston and hydraulic cylinder design is one times bigger output torque than traditional hydraulic actuator with the same cylinder diameter. And with smaller volume, lighter weight. Besides there is cushion in the two sides of hydraulic cylinder for resisting the wearing of valve sealing surface when happened fierce clash at the open or close position.
