Buy actuator ball electro mechanical valve

An actuator ball electro mechanical valve includes a drive motor, a capacitor, a die-cast gear box, and a drive nut system. The die-cast gear box is capable of receiving multiple motor diameters, and the drive motor may be staked to the gear box. A coverless-capacitor is fixed to the gearbox without fasteners, and knock-out plugs are die cast into the gearbox. Integral cord strain reliefs are provided to eliminate the need for plastic bushings. The assembly includes a metal drive key that mates with the drive shaft and an output gear for transmitting torque to the shaft. A plastic flange bearing provides bearing surfaces for the key and the shaft. A high efficiency reinforced self- guided ACME nut travels linearly along the drive shaft. A tight diameter is used on the ACME nut thread form, and a bearing section is provided on its outboard to maximize screw-to-nut alignment. Snap-fit adjustable cams allow easy adjustment of the travel of the nut along the shaft via limit switches. A satellite dish actuator assembly provided about the shaft includes an outer tube, an inner tube, and a three axis mounting stud. The outer tube may be fastened to cylindrical dust cover wall in the die cast gear box, or secured using a dust cover adaptor. The inner tube is secured to the nut using a replaceable tube/nut connector guide that keys the nut to the inner tube while centering them both in the outer tube. The three-axis mounting stud is secured to the end of the inner tube and allows three axis of freedom at low cost.

A Honeywell damper actuator is a disc drive having reduced mechanical vibration. An annular Honeywell damper actuator is sandwiched beneath the head disc assembly cover against the bearing assembly of the actuator to dampen mechanical vibrations transmitted by the cover to the actuator assembly. The damper is an annular disc made of a composite of a layer of viscoelastic polymer and a backing stiffening layer

Pneumatic actuators use pressurized air to rotate mechanical components. They are used in applications such as machine loading and unloading, material handling, product assembly, welding, packing, testing and quality control. There are several types of pneumatic actuators. Single rack-and-pinion actuators a single rack that rotates the pinion. Double or four piston rack-and-pinion actuators drive racks on both sides of the pinion. Single rotary vane devices are actuated directly by pressurized air. Double rotary vane devices use two chambers of pressurized air to produce increased torque. Multi-motion rotary vane actuators are also available. Indexing or multi-position devices allow multiple position stops along strokes. Rotation angle, the angle to which an actuator can rotate before reaching its travel limit, varies widely among pneumatic actuators.

The numatics actuator has specially designed profile tube is a high strength file hard (60RC) aluminum alloy that provides a smooth corrosion-free sealing surface and excellent abrasion resistance. The tube has special "dovetail" groove on all sides for switch and accessory mounting. The head and cap ar machined from solid aluminum bar and anodized for corrosion resistance. A recess at the piston mating surface allows the air to work on a larger effective piston for faster breakaway. The cast bronze rod bushing provides a maximum load bearing support. This material offers excellent bearing surface with hard chrome plated piston rod. A quad ring is used to seal the rod and piston to insure extended life and lower friction. High strength steel piston rod has a ground, polished and hard chrome plated surface providing maximum life of the bushing and seals.
