Angle stroke pneumatic actuator

1、 Overview
As an important field control equipment in automatic control system, the angle stroke pneumatic actuator adopts ISO5211 bottom connection standard, which can be easily matched with rotary valve (such as butterfly valve, ball valve, plug valve) and damper. Its output angular displacement is 0 ∽ 110 ° or other angles, It can be widely used in power station, metallurgy, petroleum, chemical industry, water conservancy, machinery, light industry, fire protection and environmental protection. DA series pneumatic actuators produced by Zhejiang Shenyi are simple in design and compact in structure. The whole series covers 15 specifications and can provide the most reasonable solution in the range of output torque 6N. M ∽ 3200n. M. This series of pneumatic actuators can be added with options according to the user's requirements, that is to add various functional configurations to meet the requirements of various industrial process control. The standard shell and box body treated by phosphating and coating can adapt to corrosive working environment. The flameproof products with explosion-proof and pressure resistant structure provided in the form of option can be applied to hazardous working environment such as zone 1 and zone 2 of class IIa and IIB T1-T4 explosive mixture.
2、 Product features
It is made of extruded aluminum alloy with light weight and large torque of double piston rack and pinion structure.
-- control mode: the remote switch signal is controllable (remote 4 ∽ 20mA current signal control is optional), and the local operation knob can control the valve position on site.
-- state indication switch limit and fault alarm (optional 4 ∽ 20mA current signal output to reflect valve opening).
-- high intelligent electrical control part adopts new SOC chip control, with high degree of intelligence.
-- the protective aluminum alloy shell and box body have strong anti-corrosion ability after surface phosphating treatment. The box body with O-ring at static fit and skeleton oil seal at dynamic fit position can reach the protection level of IP68. The optional explosion-proof box can be suitable for working in hazardous working environment of IIA, IIB, T1-T4 explosive mixture in zones 1 and 2.
High efficiency and low noise precision rack and pinion structure, small clearance, high efficiency, low noise and long service life.
