SECTION 3: INSTALLATION: Valve
3.01 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 which 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.
3.02 INSTALLATION PROCEDURE: Valve to Actuator
