Actuators and Controls
G Series
• NAMUR
The shaft driven accessory interface conforms to the
NAMUR standard and is identical on all G-Series actuators,
allowing for standardization of accessory mounting hardware
and installation practices
• Pneumatic and hydraulic scotch-yoke actuators
• Automates ball, butterfly, plug valves and any other 90°
rotating mechanisms
• Standard operating pressures:
Pneumatic — to 200 psig (14 BAR)
• Standard operating temperature is -20°F to +200°F
(-29°C to +93°C)
Optional trims available:
0°F to +350°F (-18°C to +177°C)
-50°F to +180°F (-46°C to +82°C)
• Mechanical and hydraulic manual overrides
are available
• Salt Spray Testing per ASTM B117 criteria. Construction
features prevent water ingress, allowing G-Series actuators to meet IP 66 and IP 67M specifications and severe
high pressure water deluge test
• MSS and ISO Valve Mounting
The G-Series valve interface meets the dimensional
requirements of MSS SP-101 or ISO 5211 defined for
each torque range
• Operating Ranges
G-Series double acting actuators produce guaranteed minimum torque outputs from 10,000 lb-in. up to 6,000,000 lb-in.
The spring return units produce spring torques from 2,500
lb-in. to 3,000,000 lb-in.
