TRUNNION BALL VALVE
INTRODUCTION FEATURES
INTRODUCTION
EMERGENCY SEALS
ANTI-STATIC
Stem Because the ball and stem in a ball valve are suspended
on non-metallic parts, i.e. the seat seal and stem seal,
there is a possibility a static charge may build up on the
Antistatic stem-ball, a mechanical (antistatic metal spring and
Assembly ball) is introduced in the design to maintain the metal-
to-metal contact between the rotating ball/stem and
the valve body which will ground any charges to the
valve body.
Stem
BLOWOUT PROOF STEM
The valve stem is made with a shoulder at the bottom Stuffing box
end. It’s securely retained by the stuffing box, to avoid
that the stem, under certain operating conditions,
accidentally blows out. Other designs are available on Body
request.

Introduction.Figure number system uses a code consisting 14 digits of letters and numbers to represent the
specification of a valve of certain specification. Of 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.To use 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.
