On Off Valve Actuator Pneumatic Butterfly Valve Actuator ATEX

pneumatic actuator

The combined effect of air-flow friction in the tube, flow limitations inherent to the controller mechanism, and volume inside the valve actuator conspire to create a sluggish valve response to sudden changes in controller output signal, not unlike the response of an RC (resistor-capacitor) time-delay circuit where a step-change in voltage input results in an inverse exponential output signal.

If the pneumatic valve actuator is driven by an I/P transducer instead of directly by a pneumatic controller, the problem is lessened by the ability to locate the I/P close to the actuator, thus greatly minimizing tube friction and thus minimizing the “time constant” (
) of the control valve’s response:

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.
