Due to the fully Welded Ball Valve valve seat is composed of a
carbonized sealing ring and
a disc spring, it has strong adaptability to changes in pressure
and temperature, and will not produce
any leakage within the marked pressure and temperature range.
Design Features
Anti-Blowout Stem Design
Stem seal integrity is achieved by the three o-rings (or two
o-rings and a graphite gasket), which
can be interchanged with new ones under pressure on the line.
Emergency Sealant Injection System
The Sealant Injection System locates on the bonnet that can be
utilized in case of emergencies,
o-ring damage and stem leakage occurs.
Emergency Seat Seal
Special sealants may be injected thru fittings located on the
adapter flanges to restore sealing
integrity if damaged. A second internal check valve provides backup
to the fitting.
Heavy Duty Bearings
The ball is supported by heavy duty coated Steel Bearings. Thrust
load on the ball is
supported by large trunnions mounted within captured trunnion
blocks for getting low operating
torque and durable seat.
Double Sealed shell Connections
Double o-rings or a o-ring and fireproof gasket on body/adapter
connections ensure reliable sealing.
This makes the P3 suitable for above or below ground service.
Antistatic Device
Springs between the trunnion and the ball or the stem and the gland
plate permit current switching
effect in all valve components.
Extend Stem
When the Fully Welded Ball valve is installed underground or
buried, the valve stem can be lengthened.
The pressure relief valve, blowdown valve, and grease injection
valve are also extended to appropriate positions.
