The valve principles are listed below:

Principle		Trim type	Application
1.	Basic Disc	BD	Simple rigid design
2.	Pico Disc	PD	Wide range for large range ability
3.	Large Cv disc	LC	“Full bore” design with Cv value up to 650
4.	Wide range Low noise disc	WL	Large range ability icw low noise production
5.	Low Noise disc	LN	Low noise design icw strainer
6.	Filter Disc	FD	Filter to avoid clogging up the system
7.	Cage Disc	CD	2 stage flow control
8.	Diamond Disc	DD	For extreme heavy duty applications
9.	Dual Orifice	DO	High range ability and dual applications
10.	Micro Disc	MD	Micro design for very small Cv values

These internals can be executed in both angle and inline body styles depending on the piping configuration.

The product range is:

Body size: ½ - 6”
Pressure rating: 150 – 2.500 lbs ANSI
2.000 – 15.000 lbs API
Cv value: upto 650

Material combinations are based on customer requirements and can easily be adapted. At the download section you will find information with regard to the recommended or most common material combinations.
