THE URD Series Discharge
Silencer is a heavy-duty, all welded unit constructed
of carbon steel sheet and plate. It provides pulse control
and silencing adequate for most sub-critical PLV applications.
Sizes 4" and larger are equipped with flanged connections
drilled to 125/150 lb. ANSI specifications. Smaller sizes
are standard with male threaded pipe nipples. Exterior
surfaces receive a shop coat of rust inhibitive primer
and may be finish painted in the field if desired. The
URD Series is the basic end inlet/end outlet configuration.
A low side inlet version is designated the URDY
Series; high side inlet, URDH Series; and low opposed
connections, URDS Series. The four types are fundamentally
alike and the performance is identical. (Sizes 6" and
smaller are URB Series rather than URD.) Mounting brackets
and other options are available.
Note: Sizes 1" thru 6" are URB Series; sizes
8" thru 30" are URD Series. Both series are
fundamentally the same in design and the performance
characteriestics are identical.
