Product Description

Application
The angular stroke cylinder piston actuator is suitable for A400, A450, A760, A770 and A780 series control valves. Single-acting model: 831, double-acting model: 832

Features
·  Compact double-piston rack and pinion mechanism, with reliable and stable angular stroke output
·  Die-cast aluminum alloy cylinder body, light weight and resistant to high pressure; standard connecting flange, facilitating replacement and installation
·  Output shaft top design facilitating manual operation and easy to maintain; customizable module combination of manual mechanism that can be installed and replaced according to user demands
·  Aesthetic and clear connection of indicators, limit switches, stroke indicators and valve positioners
·  Roll finishing inner wall of cylinder with strong wear resistance and long service life
·  The regulation type adopting internal air supply structure, without external pipeline, micro-positive pressure relative to external atmospheric pressure, and strong corrosion resistance
·  Aesthetic and firm plastic-sprayed surface with strong corrosion resistance
·  Easy exchange of single- and double-acting mechanisms, requiring only installing or removing the spring after the cylinder head is replaced
