4 INFORMATION SECTION 1: INFORMATION 1.01 DESCRIPTION The Amflow A6 Actuator is a DC gear driven motor actuator designed to accommodate the Amflow AM7 Series, AM8 Series, AM9A, AM10A, AM11A Flow Control Valves and PR7, PR7B, PR15 Back Pressure Regulators in hazardous area usage. The Amflow A6 Actuator is designed to be panel mounted, reference Section 2.11 NOTE: Orientation is not important. Once the Amflow A6 Actuator is installed, the valve is mounted into the BEARING HOUSING (Item 5) and locked in place by the three (3) SET SCREWS (Item 49). The Inlet and Outlet ports of valve will then need to be connected to the system. The Amflow A6 Actuator has two different available certified communication protocols: HART / 4-20mA and H1 FOUNDATION fieldbus.. These protocols provide ease of use in the field with their own embedded web pages eliminating third party communication devices DESIGN FEATURES Normal module operation includes valve position, current limit, pressure & flow feedback.

22 INSTALLATION: Actuator SECTION 4: VALVE INSTALLATION to ACTUATOR 4.01 VALVE INSTALLATION PRECAUTIONS Good system design is critical to the optimum operation of the Amflow Valves. At a minimum, the design should include: Isolation valves located near inlet and outlet ports of the Amflow Valve. (The outlet isolation valve is normally a three-way valve that can be incorporated into the calibration loop.) IMPORTANT: The importance of proper media filtering cannot be overstated. It is strongly recommended that filters be placed on both the suction side and the pressure side of pump. It is not unusual to have individual filters inline for each valve. The recommended micron size of the high-pressure filter is somewhat dependent on the specific configuration of any given Amflow Valve. However, a 50-micron filter size is generally adequate for most applications. The system design should take into consideration that materials that come into contact with the injected media should not contribute to foreign matter entering into the system. This means it is unwise to use material that can be easily corroded, such as mild steels. A check valve located on the outlet side of each Amflow Valve is strongly recommended. There are a number of reasons for this: The first and most obvious is for safety considerations. The second is to prevent a massive backflow through the Amflow Valve. This backflow can occur if there is a pump failure or some other system failure that would cause a loss of positive pressure across the Amflow Valve. The Amflow Valve is designed to accommodate some backflow conditions; however, piston seal damage can occur if backflow is excessive. The seal is designed to fail under certain conditions in order to prevent damage that is more serious to the valve.
