We can supply various standard valves
The product design and manufacture of full compliance with API Spec
6A "wellhead and christmas tree equipment specification"
requirements, compliance with API Spec 6A specifications
facility(at home and abroad) mating and used interchangeably.
This valve belongs to check valve, which by media pressure to
achieve metal to metal seal between the spool and the body, The
higher the pressure medium, the better the sealing performance of
the valve and at all times bearing pipeline pressure
The valve body is made of alloy steel forging, with strong
mechanical properties, can withstand high pressure, with safe and
Bonnet connect with valve body by bolts, sealing ring on bonnet
seal with inner valve, it has a reliable seal performance. It makes
valve cover and valve body assembly space is very small (designed
as 0), thus reducing the corrosive medium on the bolt and screw
hole erosion and reduce the load.
Valve plug and valve sealing surface welding by hard alloy, so that
it has good wear resistance and corrosion resistance
performance.The material of valve plug id anti-sulfur steel. Other
parts are adopt hardnedd limited methods, so that the valve can be
used in environments containing H2S.
