Operation Manual
Pneumatic Diaphragm Valves (normally open)
(Models AK/AP/AZ3080, AK/AP/AZ3580, AK/AP/AZ3585, AK/AP/AZ4580, and AP3708)
A. General information
AP Tech normally open (NO) pneumatic diaphragm valves are used in gas delivery systems to
control gas flow. Many different models are available with different pressure ratings, flow
capacities, and porting configurations.
Refer to the appropriate catalog data sheet for specific product information.
B. Installation
1. Prior to installation, verify that the operating characteristics of the valve as described
below are appropriate for the system in which it will be installed.
a. Verify the materials of construction are compatible with the intended process gas.
b. Verify the pressure and temperature ratings are acceptable for the intended application.
c. Verify the actuation pressure supply is appropriate.
d. Verify that the flow capacity (C
v
) of the valve is appropriate for the application.
2. Inspect the valve to determine the flow path through the valve and how the valve will be
installed in the system.
a. An inlet (upstream) port is defined as a port connected to the region below the valve seat and
may be labeled with an “IN” marked into the body near the port.
b. An outlet (downstream) port is defined as a port connected to the region above the seat and
below the diaphragm. The outlet port is usually not labeled, but may be marked “OUT”.
c. The traditional flow direction is inlet to outlet, but AP Tech valves may be employed in
either traditional flow direction or the reverse.
d. On Series DV Monoblock valves the port that is common with the block valves is marked
with a “
C”. No other marking is shown. Refer to Technical Bulletin 205 has schematics of
the monoblock configurations and more detailed information.
