In addition to provide you with the christmas tree, tubing head and other oil equipment, we also offer you different types of high pressure valves to use in oil exploration projects, such as gate valve, ball valve, expansion valve, throttle valve, mud valve and other manual valves or hydraulic valves.

1.Gate valve

1.Non-rising stem (no lift)structure
2.The seal between valve and bonnet, gate and seat is metal to metal type.
3.Between stem and bonnet have back seal structure, so that valve with pressure to replace packing stem
4.Metal to metal seal between gate and seat, and the surface is weld overlay with hard alloy, which have features of corrosion resistance and washing resistance
5.Working pressure :14MPa~105Mpa
Nom bore :2-1/16" ~4-1/16"

1.It is rising stem structure with balance trail stem
2.Between body and bonnet , gate and seat are metal to metal seal
3.Between and bonnet are back seal structure so that replace packing stem with pressure.
4.Gate and seat surface are hard alloy , resistance corrosion and bushing
5.Working pressure :14MPa~105MPa
6.Non bore :2-1/16"~ 4-1/16

1.Remote hydraulic control
2.Hydraulic actuator
3.Working pressure :21MPa~105MPa
4.Nom bore :2-1/16 "~4-1/16"

Gate thickness is reduce when switch , reduce gate and seat seal corrosion and switch torque

1.The gate is expanding when valve start and finish, seal is safety and convenience.
2.Applicable in the wellhead of steam injection, thermal production and environment with high temperature.
3.Working pressure :14MPa -70MPa
4.Nom bore :2"-4"

1.It is repair and replace valve part on pipeline
2.End connection is union , flange
3.Working pressure 10000PSI~15000PSI

1.Valve body ,bonnet ,gate and stem is made of low alloy steel or stainless steel, valve. Seat is made of Nitrile rubble。
2.Mud valve can be applied in the mud circulating pipe line
3.End connections: flanged ,threaded and union
4.Replacement and repair of valve core is conveniently
5.Working pressure 2M, 3M, 5M
6.Nom bore (inch) 2, 3, 4, 5

1.Stem and valve bore is made of hardness alloy.
2.Feature of abrasion resistance, wash resistance and reliable serviceability
3.Apply for Christmas and wellhead equipment
4.Working pressure :2000~20000Psi
5.Nom bore :2-1/16"~ 4-1/16"

1.Bean of choke is made of tungsten carbide or ceramics, so it has feature of abrasion resistance , wash resistance and reliable serviceability ,which apply for wellhead and Christmas tree equipment
2.Working pressure :2000~20000Psi
3.Nom bore :2-1/16"~ 4-1/16"

1.Standard :API 6A
2.Stem and valve core are made of tungsten carbide
3.Has feature of abrasion resistance , wash resistance and reliable serviceability
4.Apply for choke manifold
5.Actuator type: hydraulic actuator
7.Nom bore :2-1/16"~ 4-1/16"

1.End connection is meet with API 6A specification
2.Working medium is single direction
4.Working pressure (psi): 2M, 3M, 5M, 10M, 15M
5.Master bore (in): 2-1/16,2-9/16,3-1/8(3-1/16), 4-1/16

1.Ball valve is meet with API Spec 6D specification
2.Technical parameter
3.Rating pressure: 150 lbs~1500lbs
4.Nominal bore: 2"-30"
Technical feature
1.Since seat is floating so that ball and seat joint
2.very well and credibility seal
3.Fixed ball structure and switch torque is little

High pressure union is introduce into international technical, and made of high strength alloy. Strictly heat treatment is guarantee joint has metallurgical structure and bear capacity , which material is meet with American ASTM and AISI standard , seal is credibility , installation quickly and exchangeable . Product joint is used pipeline threaded, tubing threaded, butt weld and non-pressure seal connection.
