rack and pinion quarter-turn pneumatic rotary actuators control butterfly valve ball valve

Valve Function
Throttling valves can be moved to any position, including fully open or fully closed, within the stroke of the valve. Typically, valve actuators are added to throttling valves as part of a control loop that includes a sensing device and circuitry.

Start/stop valves, also known as on/off or isolating devices, limit actuator motion to preset open and closed positions.

More information on valve types and valve actuators can be found at IEEE GlobalSpec's Valve Types and Valve Actuators pages.

Actuation Devices
Pneumatic valve actuators and hydraulic valve actuators use several different types of actuators.

XM series pneumatic actuators statement of usage and selection

• Through research development and design XM series pneumatic actuators incorporate the latest technology materials and innovative idea. The product proudly boasts the following features.
• Full conformance to the latest specifications: ISO5211,DIN3337 and VDINDE-3854,NAMUR.

• The extruding high intensity aluminum body possesses a honed internal surface coated with hard anode oxygenation for long life. Low coefficient of friction and swift performance.

• Excellent compact and modernized construction along with multi specifications makes the selection both economic and beneficial.

• All acting surface adopt high quality bearing resulting in low friction, high cycle life, and no noise

• The two independent external stroke adjustment bolts can easily and precisely adjust ±5°at both open and close directions.

• Same outline actuators have the functional modes of double acting and single acting (Spring -Return). The Spring-Return has the normally-open and normally-close styles.

• Multi function indicator with NAMUR is convenient for mounting accessories.

• Pre-compressed load spring is convenient for safe mounting and tear down procedures.

• Die-casting aluminum pistons and end caps have high intensity and light weight.

• Different O-rings materials are available for high and low temperature.

• Solenoid valves are easily mounted without any connecting plank.
