老品牌气动头    气动执行器   表面烤漆处理    生产气动执行器20年

简介：
德国vatten VA系列气动执行器是设计紧凑、寿命长、质量高、齿条活塞式的气动执行器。该产品用于90°旋转的阀门中，例如蝶阀、球阀、风门阀等。采用德国先进的生产工艺和工艺技术在产品质量和性能上做出了VATTEN独特，鲜明的可观价值。
指示器
每一个标准产品上都装有一个蝶式开关指示器
输出轴
镀镍合金钢、高精密一体式
输出轴同时符合NAMUR、ISO5211、DIN3337标准。
缸体
缸体材质为铝合金，内外表面经过阳极氧化及抛光处理到45-50u。同时外部经过镀镍处理，使气动执行器的防腐性能大大提高。内径缸体经过抗磨处理保证了活塞摩擦力小值。
端盖
铝制压铸，环氧树脂高温处理，防腐性能极好！
活塞
铝合金重型压铸而成，带有优质密封件，使执行器在一定输入压力下输出的扭矩。安装位置对称、运作迅速、使用寿命长，简单的颠倒活塞就可以改变旋转方向。
行程微调
通过两个螺栓进行+ -5°微调并在0°和90°两个位置进行微调，称为双保险微调。
重型负载弹簧
德国进口弹簧VATTEN工艺 复合高强度弹簧高强度合金钢制作保证了性能稳定、寿命长。
密封
采用NBR-70橡胶密封圈，确保执行器在正常温度下运行可靠。如果特殊环境需要低温和高温可选用氟橡胶的特质密封圈（采用时备注详细）。

Maintenance & Operating Instructions

VATTEN? ACTUATOR OPERATIONNOTE: For optimal operation, VATTEN actuators should be run with a supply of clean, lubricated air.SPRING RETURN ACTUATORSAir to PORT 2 (the right hand port) causes the actuator to turn CCW. Loss of air to PORT 2 causes air toexhaust and the actuator turns CW. This is the FAIL CLOSE operation.DOUBLE ACTING ACTUATORSAir to PORT 2 (the right hand port) causes the actuator to turn CCW. Air to PORT 1 (the left hand port)causes the actuator to turn CW.DISASSEMBLING STANDARD ACTUATORSIMPORTANT: Before beginning disassembly, ensure that the air supply to the actuator has been disconnected, allaccessories have been removed and that the actuator has been dismounted from the valve.1. Loosen the end cap fasteners (22) with a wrench (size varies depending on actuator model). On the spring returnactuator, alternate 3 to 5 turns on each fastener until the springs are completely decompressed. Use caution inremoving the cap since the springs are under load until the fasteners are fully extended.2. Remove the pinion snap ring (10) with a lock ring tool. The indicator (7) may now be removed.3. Turn the pinion shaft (2) CCW until the pistons are at the full end of travel. Disengage the pistons (11) from thepinion. (NOTE: Low pressure air--3 to 5 P.S.I. MAXIMUM--might be required to force the pistons completelyfrom the body.) Note the position of the pistons before removing them from the actuator body. The part numbersof the pistons are located on the side and should be right-side up on an actuator with a standard orientation.4. Remove the pinion through the bottom of the actuator. The actuator is now completely disassembled. Allreplacement parts may now be put in. VATTEN recommends that all wear parts (3, 4, 5, 6, 12, 13, 14) bereplaced before reassembly.REASSEMBLING STANDARD ACTUATORSIMPORTANT: Be sure that the actuator surfaces are free of grit and scratches before reassembling.1. Apply a light film of grease to all o-rings and the pinion before replacing.2. Put the pinion (2) back through the actuator with the flats of the pinion shaft running parallel with the body.3. When reassembling the actuator, make sure that the piston racks are square to the actuator body and returned totheir original orientation. (NOTE: The normal operation of all VATTEN actuators is FAIL CLOSED. If you wantto change the orientation to FAIL OPEN, rotate the racks 180o to create a reverse operation.4. When replacing springs in a spring return actuator, ensure that the springs are replaced in their identical positionin the end cap from which they were removed. (NOTE: In some circumstances, you might want to change thestandard 80 pound spring set to fit your application and available air pressure. Changing the spring sets onVATTEN actuators requires no special tools. Please refer to the spring combination torque chart in our catalogfor the inner and outer spring combinations that will allow you to operate with the spring set that you desire.5. Seal the end caps with a petroleum lubricant and bolt to actuator body.6. Check the seal of the actuator by covering seal areas (pinion, end caps) with soapy water and using low pressureair to the actuator to ensure that no bubbles are produced.
