GT series part-turn valve pneumatic actuators are new series, whose rotary angle of output shaft is 90°. It was made by TIANJIN BAILI ERTONG MACHINERY CO . LTD. It combined with ball valves,butterfly valves for pneumatic valves . GT actuators are also suitable for other mechanic devices with 90°movement.

1. Pressure of air supply ：0.1～1MPa
2. Rotary angle of output shaft ：90°±2°
3. Circumstance temperature ：-20℃～+90℃
4. The air supply should be clean、dry, no corrosive gas and other media
5. Power supply for electromagnetic valve： AC220V or DC24V
6. Stroke switch capability:AC380V or DC220V

Feature ：

• Air supply ： filtered,dry or lubricated, pressure min 1Bar(14Psi), pressure max 10Bar (142 Psi).
• Anodic polishing on internal surface for minimum friction and long duration.
• Sliding bearings made by low friction material, to avoid metal to metal contact, easily replaceable or maintenance.

Bottom fixed hole for actuator to valve assembling and centering, as ISO 5211 standard.

• Bottom shaft assemble hole, as ISO 5211 standard,double square hole for assembling on valves with square stem in line or at the angle of 45°.
• Position indicator on request.
• Standard execution temperature range ： -20 ℃ ( 4°F ) to + 90 ℃ ( 194°F ).
• External protection ： corrosion strength to 500 hours in salted fog.
• Each actuartor is branded with a progressive serial number for easy identification and traceability.

100% of actuators are working and sealing tested.
