Product details:
GT Series Pneumatic Actuators
First, the design features
A unique bi-directional stroke adjustment;
2, a compact dual-piston gear type structure, meshing is accurate, stable output torque;
Extruded aluminum alloy, the cylinder is the hard anodizing treatment, the surface texture of hard, wear resistant;
4, piston with mechanical Road and O-rings and bearings, to avoid non-metallic and metal contact to reduce the friction coefficient;
5, connecting dimensions according to international standards ISO521-DIN3337-VDI/VDE3845 that curtain, can beinterchangeable with the vast majority of ordinary pneumatic actuator;
6, double acting and single acting (spring return) type using the same themes and cover;
7, all moving parts are bearing wear-resistant materials;
For stomatal NAMUR standard or with the adapter plate NAMUR standard. With plate solenoid valve can be installed directly;
9, the unique position indicator;
10, according to the needs for support to install the solenoid valve, reply, locators (opening direction), triple pieces andhand-operating institutions.
Second, the technical data
1, the working media: dry or lubricated gas, non-corrosive gases
2, the gas supply pressure: two-way return 4 ~ 8bar; spring return 5 ~ 8bar
3, temperature: -20 ℃ to +80 ℃
4, external stroke adjustment: 90 ℃ ± 4 ℃
5, internal stroke adjustment: 90 ℃ ± 4 ℃

Third, the principle of operation
| Double-action (top view) | Elastic recovery (top view) | ||
| Port “B” port “A” | Port “B” port “A” | Port “B” port “A” | Port “B” port “A” |
| Port A gas area of the piston to leave positionmove towards the bottom segment, the gasdischarged from the port B. | Port B gas area of the piston toward the center of mobile gasdischarged from theport A. | Gas area of the port Amoving piston to leave, tomove towards the bottom of the location of the compression spring,exhaust gas from the Port B. | Stop the gas source andpower outages, spring-driven piston toward thecenter position of the mobile gas dischargedfrom the port A.。 |
