Rack & Pinion Actuators

Siemens Industry, Inc.

Description

The Pressure Independent Control Series Rack & Pinion Actuator couples an

OpenAir® GPC Actuator to a 1-1/2- or 2-inch Pressure Independent Control Series two-

way valve using a linkage. The linkage transforms the actuator rotary movement into

the linear motion required to position the valve.

Features

• Bi-directional fail-safe spring return

• Orderable as direct (Normally Open) or reverse (Normally Closed) acting

• Brushless DC motor technology with stall protection

• Pre-cabled

• Plenum-rated

• 60-second run time

• Integrated 1/2-inch NPT conduit connection

• Modulating control signal selectable 0 to 10V or 2 to 10V

• Modulating actuator has 0(2) to 10 Vdc feedback

Application

The Pressure Independent Control Series valves are used to control water and glycol

solutions to 50 percent in small to large air handling units and central plant applications.

Technical Instructions Document No. A6V11637981 March 5, 2019 Pressure Independent Control Series Rack & Pinion Actuators Operation 599-03617 assembly with GPC161.1P actuator A continuous 0 to 10 Vdc signal from a controller to Terminal Y (8, gray) operates the actuator, and the valve opens and closes. The linkage proportionally translates the rotary actuator stroke into a linear valve stem motion.
