Wellhead Check Valve
API 6A 1-13/16" ~7-1/16” 2000psi ~ 15000psi Check Valve / One Way Valve
Wellhead Check Valve:
Check valve is designed and produced entirely according to API
Space 6A Specifications for Wellhead and Christmas Tree, able to be
used interchangeably with corollary equipment at home and abroad
that is in line with API Space 6A Standard.
It relies on medium pressure to achieve the metallic seal between
valve trim and valve body, and the higher the pressure of medium
is, the better the sealing property will be. Pipeline pressure can
be bearable always to the inside of valve cavity.
Structure instruction
Check valve: mature technology, experienced, stable supply,
competitive price
It creates the metal-to-metal seal by the pressure of the medium,
the more the pressure is, the better the sealing effect is. Anytime
the valve chamber can bear the pressure of the pipeline.
Valve body is machined of alloy steel forging with a stronger
machinery properties and reliable performance.
Bonnet is connected with valve body with bolt. The seals include
the sealing ring in the bonnet and the seal in the valve body,
which makes a very small gap (0 designedly) between valve body and
bonnet, thus minimizing corrosion of corrosive medium to bolt and
screw hole and reducing bolt loading.
The sealing face between valve core and valve body is welded with
hard alloy with good abrasion resistance and anti-scour; the valve
core is made of sulfide-resistance steel and the others adopt the
process of hardness limit so the valve is able to be used in H2S
condition.
Operation instruction
According to medium flow direction and by the flow direction
indicating plate of the valve, the valve is installed. As positive
flowing, the medium lifts the valve core and pass easily; If no
positive medium pressure, valve core will self-shut off valve gate
under self-weight and spring’s tensile force, the back medium
flowing stop.
Maintenances
*The valve should be placed in the dry and airy room, and the inlet
and outlet are sealed properly.
*When the product is stored, the end flanges should be coated by
oil against rust and dirt pollution.
*The valve-core and the valve-seat must be examined every in a well
time. The attrition rate will decide whether they are used by upset
or are replaced.
*Every seal element is replaced according to its examination.
*There is a bit leak at a couple of seals of valve, and the
sealing-face may have scratch or wear. Renovation will be done
under face-off and ground finish.
*As leak appears at the middle one of the valve bores, ring gasket
should be replaced.
