Angle stroke pneumatic actuators as automatic control system is a kind of important field control equipment, use of ISO5211 bottom connection standard, can easily and rotary type valve (such as butterfly valve, ball valve, plug valve) and damper and the baffle form a complete set, its output angular displacement is 0 ∽ 110 ° or other Angle, which can be widely used in power plant, metallurgy, petroleum, chemical industry, water conservancy, machinery, light industry, fire protection and environmental protection and other industrial departments. Zhejiang ShenYi production DA series pneumatic actuator design is simple and compact structure, full series include 15 varieties of different specifications, can in the output torque 6 n. M ∽ 3200 N.m range provide the most reasonable solution. This series of pneumatic actuators can according to user requirements, increase the option that additional various function configuration, meet various industrial process control requirements. The phosphating, coating treatment standard housing and housing can adapt to corrosive environment, in order to choose a form to provide and have explosion-proof pressure structure of the flameproof products can be suitable for IIA and IIB level T1 - T4 stage explosive mixture of 1, 2 area such as place of dangerous work environment.
Product features
- fine small the extruded aluminum alloy material, the weight is light, the double piston pinion and rack structure torque big.

- control mode remote switch quantity signal controlled (optional remote 4 ∽ 20 ma current signal control), in situ operating knob can field control valve position. - status indication switch limit and fault alarm (optional 4 ∽ 20 ma current signal output reflect valve opening). - high intelligent electrical control part adopts new SOC chip control, intelligent degree is high.

- protective aluminium alloy shell and the surface of the phosphating treatment has a strong anticorrosion ability, static fit place with o-rings, movable fit place with skeleton oil seal chamber to IP68 protection level, optional explosion-proof housing can be suitable for IIA and IIB level T1 - T4 stage explosive mixture of 1, 2 area such as place of dangerous work environment. Low noise, high precision gear rack structure, clearance of small, high efficiency, low noise, long service life.
