JSC TOP ENTRY BALL VALVE FEATURE
Stem seal integrity is
achieved by the use of
three o-rings (or two
o-rings and a graphite
gasket). Upper o-ring
(or graphite gasket)
can be replaced with
the valve in line and
under pressure.

Seat Seal
Emergency ●Heavy Duty Bearings
The Sealant Injection System located on
the Bonnet can be utilized in case of
emergencies, o-ring damage, or if stem
leakage occurs.
Trunnion are supported by heavy duty Teflon
coated Steel Bearings. Thrust load on the
ball is supported by large trunnions mounted
within captured trunnion blocks, resulting in
low operating torque and seat wear.
Special sealants may
be injected thru fittings
that are located on the
adapter flanges to
restore sealing integrity
if damaged. A second
internal check valve
provides backup to the
fitting.
●
Envelope
Connections
Double Sealed
●Antistatic Device
A spring between the
trunnion and the ball or
between the stem and
the gland plate permits
electrical continuity
between all valve
components.
Double o-rings or a
combination of an o-
ring and fire safe
gasket on body/
adapter connections to
ensure positive
sealing. This makes
the P3 suitable for
above or below ground
service.

TECHNICAL SEATING FEATURES
Technical Seating Features
Line Pressure acting on the seat area (A1) does not
equalize against the line pressure acting on the seat
area (A2). The difference in the area (D1) times the
line pressure creates "piston effect" force which
pushes the seat against the ball surface resulting in
a tight effective seal,
Double Piston Seat Design
●Upstream Seat:
●Downstream Seat:
When the body cavity pressure is greater than the
downstream pressure, the body cavity pressure acts
on the seal area (A4). The net pressure difference,
acting over area (D2), pushes the downstream seat
tightly against the ball creating a positive seal.
THE ULTIMATE BENEFIT OF USING THE
"DOUBLE PISTON SEAT" DESIGN:
In case of upstream seat leakage, the downstream seat maintains a
pressure assisted tight shut off by sealing against the ball surface.
PB=Body Cavity Pressure
Self Relieving Seat Design
●Downstream Seat:
The difference in the area (D1) times the line pressure
creates a "piston effect" which forces the seat against
the ball surface. Also the springs behind the seat adds
the force to the seat which keeps the seat in contact with
the ball surface by providing the tight seal.
●Upstream Seat:
When the body cavity pressure exceeds the spring
pressure, automatic pressure relief will occur by
relieving the body cavity pressure past the downstream
seat. This eliminates the need for the body relief valve.
●Double Block and Bleed
The double block and bleed condition is
available in all seat design configurations.
When the ball is in the closed position the body
cavity pressure may be drained down to 'zero'
by opening the bleed valve and draining the
fluid by removing the drain plug. Each seat
works independently assuring tight shut off
seal against ball on the upstream and
downstream side.

TRANSITION PUPS
●VARIOUS OPERATORS
The Ball Valves can be furnished with transition pups of different length
to facilitate the installation of valve and piping on site in accordance with
existing standards..Also the transition pups are required for welding
between the valve and the pipeline. The transition piece length L is to
be specified by the customer, including wall thickness and pipe specification.
