Pneumatic Diaphragm, Pneumatic Piston, or Hydraulic Actuator. The standard configuration for an actuated valve includes a slab gate and floating seats. Actuator / bonnet assemblies and actuated valve assemblies also include an optional manual override device.

The actuator includes a manual override system that functions independently of the actuator's hydraulic piston and return spring, an externally accessible valve gate drift adjustment, an externally adjustable upstop for the actuator stem, a stem thread assembly that can be manufactured from a material different from the actuator stem to prevent or reduce the possibility of thread galling, a hydraulic control pressure porting system integral with the hydraulic cylinder to minimize space.
