Orifice Plate Assembly
• Wafer Design
• Fits ANSI 125, 150, 250, 300
• Optional Materials Available
• Easy to use size Selection Chart
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 light­weight 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 rec­ommended "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 sens­ing 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.

Sizing An Orifice Plate Bore
1. In determining a bore size, the nominal flow rate (or range of flow) and the pipe size in which the orifice plate assembly will be installed must be known.
2. Sizing a bore for:
A constant flow rate:
Select the sizing chart that matches pipe size and locate the flow rate under the nominal column which is closest to required flow; select the corresponding bore size dimension.
Example: A 6" pipe with a desired constant flow of 700
gpm.
Using the 6" chart, the closest flow in the nominal column is 670
gpm which has a corresponding bore
size of 3.80".

A flow range:
Select the sizing chart that matches pipe size and locate required flow range between the minimum and maximum limits of an orifice bore. Frequently the flow range will fit between more than one bore size. To resolve this, decide the flow rate that system will be operated at most frequently. Locate the flow which is closest to this under the nominal flow column, and select the corresponding bore size dimension.

6" Valve / Pipe Size
Example: A 6" pipe with a flow range of 300-1000 gpm. Using
the 6" chart, more than one bore size can accom­modate this range. The most frequent flow rate will be 500 gpm. Using the nominal flow column, the closest flow is 520 gpm which has a corresponding bore size of 3.40"
