Mounting ISO 5211 Pneumatic Actuators to GB Series Ball Valves
Field mounting an ISO 5211 pneumatic actuator is just one of the options allowed by the bolt pattern design of the GB valve body, providing inventory and installation flexibility. Learn how easy it is to locally configure an ISO 5211 actuator to your GB series ball valve.

The GB full-bore, full-flow ball valve offers industry leading performance, material selections, and end-connections while providing you a lower overall cost of ownership by reducing inventory levels and reducing maintenance costs.
One way the GB valve minimizes your inventory is with several locally configurable options. The GB valve body features a bulk pattern which can be used to add a lockout handle, panel mount kit, or an ISO 5211 pneumatic actuator.
Let’s look at how easy it is to add these options. You will need a 9/16-inch wrench to disassemble the handle from the valve body. Start by ensuring the valve is in the open position. Next, remove the following items: upper stem nut, the non-locking stock plate, the handle, and the grounding spring. Discard the non-locking stock plate and set all other components aside for later use.
Let’s walk through how to add on an ISO 5211 pneumatic actuator on a standard GB valve assembly. You will need a torque wrench, a 3/16-in hex key, a 5-millimeter hex key, and a 9/16 open end wrench.
First insert the mounting bracket over the valve stem and attach the valve body while use the four cap screws. Torquing the screws to 75-inch pounds.
Next assemble the coupling shaft into the coupling spring and coupling sleeve to complete the coupling sub-assembling. Note the proper orientation of the coupling sleeve. Slide the coupling sub assembly on to the valve stem. Next place the actuator on to the coupling end-valve assembly. Attached the actuator to the mounting bracket using the four actuator cap screws. Torquing the screws to 75-in pounds.
If the torque wrench cannot fit in the space, tighten with a wrench to the approximate torque. Verify that the ball orifice is oriented correctly to the actuator cap. When the actuator and valve are in the open position, you’ll be able to see through the orifice. You can also verify correct orientation by confirming that the stem flats are parallel with the actuator cap indicator. Finally, make sure the coupling sleeve goes over the packing stem nut. If necessary, turn the stem nut slightly clockwise to engage it with the coupling sleeve.
