Pneumatic actuators is a combination of unique style, advanced
technology, sophisticated processing and manufacturing, economical
and practical, save a space, module design, can be directly
installed other attachments, increase the efficiency and economy.
Maximum rated air pressure is 8 bar, the minimum air pressure is
2.5 bar.
Using gas source: after dry clean air filter or lubrication, non -
corrosive gas.
The lateral aspect of A cylinder body two independent travel limit
switch direction adjusting bolt in 2 + 5 ° adjustment,
The actuator position with the valve in full open position.
B end cover high die casting aluminum, the surface anti-corrosion
thermoplastic coating, compact unibody design, all single action
and double action
Actuators have the same cylinder block and cylinder head, by adding
or remove the spring to change the way of action.
C combined load on the spring design is suitable for various
installation and removal safer, also don't have to worry about
spring pop-up cuts.
D fasteners are all made of stainless steel materials.
E connection size all accord with international standard: with
ISO5211 DIN3337 and VDI/VDE3845, air interface
In accordance with NAMUR standard.
F shaft end with NAMUR standard slot multi-function location site
visible indicator, convenient installation, in accordance with
VDE3845
Standard signal switch box, locator, position induction switch and
other accessories.
G gear axis: standard for nickel plating processing, to overcome
the external and internal corrosion, strong commonality, resistance
to fracture, bearing guide
Gear design, and improve the safety of the parallel to the output
shaft and diagonal square transformation installation, good
flexibility.
H the new aluminum alloy cylinder block, the extrusion cylinder
manufacturing precision machining center, inner and outer surface
hard anodized
To deal with.Small friction coefficient, long service life.
I the composite piston ring on the piston, rack on the back of the
guide bearing, the output gear shaft bearing wear ring, which can
realize running accuracy,
Reduce the friction.
J double piston design of gear and rack structure is compact, two
piston symmetrically installed, constant, the output torque force
equilibrium, quickly
Stable and high precision.
K internal gas path, the economy and do not need to connect the
leakage pipe.
The working principle and direction of rotation
The standard direction of rotation is clockwise, counterclockwise
to open
Professional manufacture STV Pneumatic Cylinder Valve Actuator
