Pneumatic actuator specification a, product overview
1, the outer cylinder body side two independent travel limit switch direction adjusting bolt in 2 plus or minus 5 degrees adjustment, make the actuator in the full open position or seated position with the valve switch position.
2, the end cover USES the high die casting aluminum, the surface anti-corrosion thermoplastic coating, compact unibody design, all actuators of single and dual action have the same cylinder block and cylinder head, by adding or remove the spring to change the way of action.
3, combined preload spring design is suitable for various occasions and remove the safer, also don't have to worry about spring pop-up cuts.
4, fasteners are all made of stainless steel materials.
5, shaft end multi-function with NAMUR standard slot position scene visible indicator, convenient installation, up to the standard of VDE3845 induction switch signal switch box, locator, position and other accessories.
6, tooth axis: standard for nickel plating processing, to overcome the external and internal corrosion, strong commonality, resistance to fracture, gear bearing guide integration design, improves security, parallel to the output shaft square and diagonal square transformation installation, good flexibility.
7, the new type of aluminum alloy cylinder block, the extrusion cylinder manufacturing precision machining center, internal and external hard anodized surface. Small friction coefficient, long service life.
8 composite piston ring, piston, north of rack guide bearing, the output gear shaft bearing bad wear-resisting, can realize running accuracy, reduce the friction.
9, double piston design of gear and rack structure is compact, two piston symmetrically installed, constant, the output torque force equilibrium, quickly smoothly, with high precision.
10, internal gas path, the economy and do not need to connect the leakage pipe.
2, selection of actuators with double acting
actuators, make sure the valve torque, combined with the safety coefficient, number of safety valve with different medium, temperature, pressure, friction between the friction force between valve core and valve seat and many other factors, affect the operating torque.
example: the known butterfly valve torque = 150 nm, using the medium as water; Temperature: room temperature, the air pressure for 5 bar, to the safety coefficient is 20%; Safety moment: 150 + 20% = 180 nm control double-acting actuator torque, check pressure of 5 bar column in the table along the column data for equal or close to 180 nm.
3, pneumatic actuator output torque table ( Unit N. m）
4, select the AT type pneumatic device of ten reasons
1, cooperate with the bottom of the shaft for the small module gear key installation and dismantling is convenient for different angles.
2, distribution board type electromagnetic directional valve in accordance with NAMUR standard, simplified the device, without any pipe connection. 3, at the top of the shaft top with switch indicator. 4, can choose spin clockwise and anti-clockwise reverse rotation.
5, inside and outside the cylinder body hard anodic oxidation of corrosion on the surface, improve the life. 6, the inner surface of cylinder block special handling to ensure friction
7, the size of the flange joint accords with ISO5211 / DN3337 standards.
8, with low friction materials bearing sleeve, avoids direct contact with the metal and metal, cheaper to repair. 9, control valve link NAMUR standard 10, design and structure technology from Italy.
