1. Wafer insulation ball valve adopts integral jacket structure design, which can keep heat and cold evenly.
2. Compared with ordinary ball valves, the wafer insulation ball valve has a smaller volume, lighter weight, no leakage, and good
sealing performance.
3. The jacket is welded with carbon steel pipe and is more pressure-resistant and firmer than the cast one.
4. If the valve diameter is equal to the pipe diameter, the medium flows in a straight line with low resistance, which can
effectively reduce the heat loss of the medium in the pipeline.

AT series pneumatic actuators statement of usage and selection
Through research development and design AT 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.
