1. The bonnet are extended for low temperature 1. The high temperature extended structure is 1. Bellow seal extension has the bellow inside of
service, the packing position are raised to mainly to prevent scald operator during the cavity, the effective compression of the
avoid the freeze of packing which will affect operation. bellows must be greater than the opening stroke
packing sealing performance; 2. The cooling fin can be selected to help heat of the valve;
2. The gate valve shall have relief hole on radiation. 2. Bellow seal structure can effectively reduce the
upstream direction while the pressure may leakage of valve stem, the primary seal is for
remain in the cavity; bellows and secondary seal as a filler.
3. Low temperature cold isolation can be an
option to prevent cold heat exchange.

HOW THE FIGURE NUMBER SYSTEM WORKS

Introduction. Figure number system uses a code consisting 14 digits of letters and numbers to represent the
specification of a valve of certain specification. Among 14 digits, they are separated into 10 groups identified by
letters from A to J. Each group represents a parameter of a valve, together they contain almost all the essential
parameters of the valve.

Uses. Using the figure number system to generate a code is easy. Under each group, the code is shown on the left
while on the right is the meaning of the code. Start by selecting a code from group A, through group J. If the
specification of the valve is not listed, select the code for “Special “. The total length of the figure number shall be
exactly 14 digits.

Cautions. It is advised that you have as detailed the specification as possible to generate a figure number, which
means eliminating “Specials”. If you don’t have enough specification or information about the valve you are
ordering, or you’re not sure how to use the system to generate a figure number, contact one of our sales
representatives for help.

Note: FBV reserves the right to make any modifications without notice.
