REV LEVEL B
The T4400F Trifecta Valve System is typically supplied with a female NPT vent
connection and flanged end connections. (Note: Other end configurations
available upon request.) Refer to order specification or purchase order
specifications for type supplied. Valve installation should be in accordance with
standard practices for end connection provided. Flanges are raised face carbon
steel per ANSI B16.5. Threads are per ANSI B2.1. Ensure the weight of the
system is properly supported to prevent excessive stresses. Valve should not be
supported by actuator tie rods. Valve may be installed in any orientation. Ensure
flow direction is appropriate for intended installation. Valves incorporating
welded ends should follow special precaution to insure weld heat does not
damage valve seals and gaskets. Temperatures in these areas should be kept
below 200
F.
CAUTION
Vent pipe size should be equivalent to the vent fitting size
supplied. Reducing vent size may result in insufficient flow
capacity. Under
NO
circumstance should the vent be blocked
or plugged.
C.
Pneumatic/Electrical Hook Up
Utilities required for operation are electrical power and clean dry compressed air.
Wiring should be in accordance with referenced drawings and all applicable
codes. Supply air should be connected to the 1/4" NPT inlet port on the solenoid
quick exhaust module. Purge all pneumatic lines before connecting to the
solenoid assembly. The control air lines should be filtered to 40 microns
minimum. Supply air pressure must be 70 to 120 psig at all times.
WARNING
Make certain electrical supply is isolated and tagged out
before proceeding with electrical connections.
Note: Some assemblies may include an optional filter regulator that must be
mounted by the end user.
