X52E
The Cla-Val Model X52E Orifice Plate Assembly is typically used with
Cla-Val flow control valves. The orifice plate is an essential component
used to generate a specific, predictable pressure drop in the system.
The X52E uses a wafer design holder which offers a compact light-
weight assembly that is easy to install. The X52E has a Chamfered
"Inlet" side so even after installation, correct orientation can be easily
verified.
The orifice plate portion of the assembly is made of 302 stainless steel
with other materials options also available. The plate is machined to a rec-
ommended "square edge". The plate holder portion of the assembly is
Ductile Iron standard. Fusion-bonded epoxy coating is an option. The
holder may be made of other materials.
Selecting an orifice plate bore size is made by using charts provided.
We recommend installation of this assembly with the sensing port to the
side of the pipeline to prevent air pockets and obstructions in the sens-
ing line. Installation adjacent to a butterfly valve is not recommended as
the orifice plate assembly may interfere with the opening of this type of
valve.
