Pneumatic ball valve can realize on-off when matched with moving limit switch, solenoid valve, pressure reducing valve, and 0.4 0.7 MPa gas source. And output two passive contact signal to control valve on or off. Pneumatic type O shape ball valve is particularly suitable for medium which is viscous, containing particles and fiber properties. Pneumatic switch ball valve is widely used in petroleum, chemical industry, teaching equipment, light industry, high pressure equipment, pharmaceutical, paper and other industrial automatic control system, as long-distance centralized control or local control system.
AT pneumatic actuator
Gear rack Dual-piston is symmetrical, quick action and stable. High accuracy, big power output. Can realize reversed direction revolving by simple changing the piston position.
Aluminum alloy cylinder.
All the double action and single action actuators have the same cylinder and side cover.
Complex type conform to safety spring group, convenient to increase or decrease spring number.
Two separate bolts at two side, convenient regulating valve ON or OFF position. Lengthening the bolt if need all travel regulating.
Multifunction position indicator, local showing, conform to standard VID/VIE3845, NAMUR, can install and output all the accessories like limit switch box, electric positioner, location transducer.
Air source port conform to NAMUR standard, and install NAMUR standard solenoid valve directly.
Composite bearing, piston leading ring and Output shaft bearing at Gear back side is rubbing protection of metal to metal, long service life.
All fixing material is stainless steel, anticorrosive.

Wear-resisting Steel Plate is composed of low Carbon Steel Plate and alloy wear-resisting layer. When working, the matrix provides comprehensive properties such as strength, toughness and plasticity of resisting external forces, and the alloy wear-resistant layer provides wear-resistant properties that meet the requirements of specified working conditions.
Wear-resisting steel alloy wear-resisting layer and base plate are metallurgical combination. By means of special equipment and automatic welding process, the high-hardness self-protecting alloy wire is uniformly welded on the substrate, and the composite layers are one to two or even more. In the composite process, due to the different shrinkage ratio of the alloy, uniform transverse cracks appear, which is a significant feature of the wear-resistant steel plate.
The wear resistant layer of the alloy is mainly chromium alloy, while manganese, molybdenum, niobium, nickel and other alloys are added. The microhardness of carbide can reach above hv1700-2000, and the surface hardness can reach hrc58-62. Carbide alloy has a strong stability at high temperature, maintain a high hardness, but also has a good oxidation resistance, within 500℃ completely normal use.
The wear-resistant layer has narrow channel (2.5-3.5mm), wide channel (8-12mm), curve (S, W), etc. It is mainly composed of chromium alloy, while manganese, molybdenum, niobium, nickel, boron and other alloy components are added. With 40-60% carbide content, the microhardness can reach above HV1700 and the surface hardness can reach hrc58-62.
