Description
585C pneumatic piston actuators ( figure 1) provide accurate throttling or on-off control of sliding-stem valves. The
585C actuator uses a double-acting cylinder, which requires air pressure for operation.
Size 25 and 50 actuators are available as a springless construction or with a bias spring. Depending on configuration,
the bias spring will retract or extend the piston rod upon loss of cylinder air pressure. Size 60 through 130 actuators are
available as springless constructions only.
585C actuators are typically supplied with a DVC6200 digital valve controller, or a 3600 P/P or I/P analog positioner.
The 585C actuator is available with a top-mounted or side-mounted manual handwheel, depending on actuator size.
Specifications
Specifications for the 585C piston actuators are given in table 1. Some individual actuators come from the factory with
specifications stamped on a nameplate attached to the yoke.
