See Table 4 on page 10 for packing limitations.

Extended bonnet The extended bonnet protects the packing from excessive heat or cold, which may inhibit valve performance.

The bonnet is constructed of carbon steel for temperatures from -30C to 427C (-20F to 800F) and of 304 or 316 stainless steel for -100C to 816C (-150F to 1500F).

This table shows the sizes, strokes, trim values, and the Cvs at different percentages of valve opening.

In this table , you can observe that the value of Cv increases with the increased percentage of valve opening.

3A-29 INTRODUCTION Valtek uses a systematic method for selecting body types, sizes, materials, pressure ratings and trim sizes based on flow characteristics.

Valtek control valve flow capacity ( C v #, The valve sizing coefficient most commonly used as a measure of the capacity of the body and trim of a control valve is C v.

One C v is defined as one U.


gallon per minute of 60 degree Fahrenheit water that flows through a valve with a one psi pressure drop.

The general Equation for C v is as follows:.
