Installation
Install the valve and topworks
NOTICE:
The topworks size and configuration can limit the actual operating pressure. Consult the Pure-
Flo catalog for pressure limitations. Consult the factory or engineering catalog for vacuum
operation.
Consider the following information before installing the actuator:
• The maximum valve operating pressure is 10.34 bar | 150 psig. This pressure is applicable
up to 38ºC | 100ºF. Valves at maximum pressure cannot be used at maximum
temperatures.
• The maximum actuator pressure is 6.9 bar | 100 psi.
1. If you have a weld end valve, then consider the following:
If you are
welding ...
Then ...
Manually
Remove the topworks.
In line
You can weld with automatic equipment. Before you perform the weld:
1.
Remove the topworks (optional).
2.
If left installed, set the valve to the open position.
3.
Properly purge the valve with an inert gas.
2. Install the valve.
3. Prior to pressurization (with the valve slightly open), tighten the bonnet fasteners.
For more information, see
4. If you have an actuated topworks, then connect the air line.
Connection size is 1/8" NPT.
5. Cycle the valve two to three times to verify smooth operation.
Mount the topworks to the valve
1. For actuated topworks, regulate the air pressure.
If the topworks is ...
Then regulate the air pressure ...
AXS1, AXS3
In the upper cover to extend the compressor.
AXS26, AXS29
In the lower cover to properly position the valve diaphragm.
2. Install the valve diaphragm.
For more information, see
3. Assemble the valve body and tighten the bonnet fasteners.
For more information, see
4. If there is a travel (closing) stop, reset it to ensure proper closure.
For more information, see Adjust the travel (closing) stop in this manual.
Tighten the bonnet fasteners
CAUTION:
Do not tighten fasteners while the system is pressurized or at elevated temperatures (greater
than 38°C | 100°F).
1. Depressurize the system.
