Fully welded ball valve of 1/2"-56" CL150-2500 forging material, extended bonnet
KELITE fully welded ball valve, widely used in urban underground gas pipelines,natural gas pipelines and pressure regulating stations and other fields.In the past years,through continuous research and innovation and improvement of product quality.
KELITE fully welded ball valve,due to the overall structure of the
valve fully weloed construction using technology to make the
valve,the outer seal has been greatly improved,the valve's weight
has been greatly reduced (especially DN300 or less) so that the
valve installation becomes more convenient,not only reduces the
cost of construction,but also saves time.
KELITE fully welded ball valve,can be directly buried
underground.Do not set the underground valve control room, so that
operations do not need to go into the ground, just drive operation
can be carried out on the ground with a T-handle,very easy to avoid
the past due to the underground valve control room set up and there
hidden dangers.
KELITE fully welded ball valve,the valve can be designed in
different height for your users based on the depth of buried gas
pipeline.Meanwhile,also according to the different needs of users
connected to the valve port,you design a variety of port
connections for you to choose from.
Structural characteristics and advantages for fully welded ball
valve:
1. Anti-leak stem
In order to prevent the stem fly cause abnormal elevation of
internal pressure valves, dry shoulder fixed lower portion.
Further, in order to prevent leakage resulting from burnout stem
packing in a fire, the thrust bearing in the lower portion of the
contact position in the stem and body shoulders therefore prevent
the formation of anti-sealing seat leakage to avoid accidents.
2. Fire safety structure
When the trunnion ball valves normal use, the seat and the
spherical stamp law, seat retainer o-ring and seal body, which is a
soft seal, reliable seal and o-ring seat when injured, seat holder
and the body will be stamped expanded graphite such behavior fire
safety purposes.
3. Anti-static equipment
In order to prevent friction among ball, stem and PTFE static
electricity may ignite flammable materials and explosives,
resulting in an accident, in this ball valve, static-conduction
spring between the stem and the ball, the stem and the body and
therefore static ground system security to be secured.
4. Free body leaking seal structure
Smooth, double stamped gaskets and o-rings, on this basis, for this
reason as fire switch position of the valve and the valve bonnet,
high temperature, shock and uneven opening or closing torque will
not cause external leakage.
5. Low operating torque
Self-lubricating bearings installed in the friction of stem cells,
leading to wear and flexible operation and low torque.
6. double block bleed (DBB)
When the ball fully open or closed position, the transmitter
substance the body can drain cavity Center announced, emptying
devices Moreover, it is the center of the valve chamber pressure
can be released into the low pressure end of his rescue seats.
7. Emergency sealing
Composite injection hole design and install complex injection valve
located in the stem / hat and physical support when the valve stem
seal or seat damage induced leakage, such compounds can be used to
make a second check valve seal hidden installed near both composite
injection valve, to prevent the outflow of action of the compound
material, a composite of the top of the transmitter composite fuel
injection valve of fast connection connector injection gun.
8. stem extension
Underground installation valve stem can be extended to facilitate
the operation corresponding composite nozzle, the drain valve can
be extended to the highest valve.
9. Automatic body cavity relief
When the body pressure rise is not normal, such as instability,
trunnion ball valve downstream seat will be normal pressure, while
not normal automatic release of pressure, do not damage the sealing
of upstream seat.
