SECTION 1: INFORMATION
1.01 DESCRIPTION
The Amflow
®
A2-ACM Actuator is a DC gear driven motor actuator designed to accommodate a variety of
Amflow
®
products in hazardous area usage. Part compatibility includes; AM7 Series, AM8, AM11A flow control
valves and the PR7 Series and PR-HF-SSSP back pressure regulators.
The
Amflow
®
A2-ACM Actuator is designed to be panel mounted, reference Section 1.09 and 1.7. Note that the
orientation is not important. Once the
Amflow
®
A2-ACM Actuator is installed the valve can be screwed onto the
valve ADAPTER and locked in place with a 6mm set screw. The Inlet and Outlet ports of the valve will then need
to be connected to the system.
