Maximum rated air source pressure is 8bar,and minimum air source pressure is 2.5bar.
Operating temperature:Standard:-20ºC(-4ºF)to+80ºC(+176ºF)
High-temperature:-15ºC(+5ºF)to+150ºC(+302ºF)
Low-temperature:-40ºC(-40ºF)to+80ºF(+176ºF)
Air source:Dried,filtered or lubricated clean air,non-corrosion gas.a. Interface between actuator and valve: 4 or 8 bolt orifices according to DIN/ISO
5211, the axle assembles orifice according to DIN 3337
b. Interface between actuator and control valve: 7100 D/S-7350 D/S according to
NAMUR or VDI/VDE 3845, 7040 D/S-7090 D/S connecting via the adapter plate
c. Interface between actuator and signal box: according to VDI/VDE 3845Introduction
I. Actuator BodyBoy material is aluminium alloy. Internal and external surface are treated with anodic oxidation and polishing. Outer surface is nickle plated so that the anti-corrosion fuction of actuator and minimum friction against pistons can be guaranteed.
II. End CapEnd Cap made from high-pressure casting aluminum,Surfaced with anti-corrosion thermoplastic coatings,all-in-one compact structure,all single and double cating actuators have similar actuator body and cap,changes its acting mode by loading or disassembling springs.
III. Drive ShaftThe drive shaft material is medium carbon steel with fine processing and nickle plating so that the pistons have better quality in anti-corrosion, anti-friction, etc.
IV. PistonPiston material is die-casting aluminium alloy. Maxmium torque can be output when the actuator is actuated with certain pressure.
V. Piston SealNBR-70 rubber sealing is applied to ensure the normal and reliable performance of actuator under normal temperature. FPM can be also applied according to clients' requirements.
VI. Travel AdjustmentPlus/Mimus 5 degree travel can be adjusted through the two bolts.
