Detailed Product Description

The product design and manufacturing in full compliance with API spec 6A "wellhead and tree production equipment norms" requirement, at home and abroad can meet API spec 6A norms and ancillary equipment used interchangeably. This valve of the check valve. It realized the pressure on the media and the valve spool between the metal seal, the greater the pressure on the media, and good sealing performance. All times valve cavity pressure to bear pipeline.
This valve of the check valve. It rely on the media and the pressure to achieve spool valve between the metal to metal seal. The greater the pressure on the media, the better sealing performance. All times valve cavity pressure to bear pipeline.
This valve alloy steel forgings for processing form and has strong mechanical properties, can withstand high pressure, a safe and reliable performance.
Valve and the valve cover bolts used connections, seals for valves and valve seals stamped with the seal wall, sealing performance and reliable. It enables the valve cover and valve assembly space small (design 0), thereby reducing corrosion medium on the bolts and Screw Hole erosion and reduce the bolt load.
Spool Valve sealing surface and surfacing Carbide, so that it has good wear resistance and corrosion resistance, spool-sulfur material to use steel, other parts of the methods used hardness limit, the valve can result in containing H2S the use of the environment.

Instructions:

According to the valve body will flow valve installed on the pipeline.

Spool pressure on the upstream and downstream of the pressure to achieve a result of the campaign and sealed card will spool death.

Maintenance note

The replacement spool and seals

Rip valve cavity pressure, the demolition of valve cover bolts, remove valve cover.

Remove spool and replaced by new spool. Replacement, they will - and will spool valve sealing surface grinding together.

Check whether the valve cover seals intact, if damaged, should be immediately replaced.
