Cryogenic Ball Valve
According to the standard requirements, the ball valve with temperature lower than – 50C is generally designed with a long neck structure to increase the temperature at the filler and ensure the reliable sealing of the valve rod filler. The neck length is generally designed according to the standard requirements, and the user can also meet the contract requirements if he has special requirements.

Nickel Base Alloy High Pressure&Temperature Check Valve
In order to ensure the high requirements for the tightness, reliability and safety of the screen door, the valve body is made of nickel base alloy as a whole, or fabricated and welded.
-
Nickel Base Alloy High Pressure&Temperature Globe Valve
In order to ensure the safety and reliability of the valve, the valve body is made of nickel base alloy material, which is made of overall silver or reported and welded. Due to the influence of structural factors, the cut-off adjustment is subject to large discharge and high pressure drop.
-
Froging Steel Valve
There are corresponding forged steel adjusting series for gate valve, globe valve and ball valve. Die forging is used for DN15-DN80, and free forging is used for ≥ DN80. Simultaneous multidirectional die forging (Hollow silver manufacturing technology) is also gradually applied to high-end products.
-
ANSI Butterfly Valve
Tri-eccentricity structure, butterfly plate and adjusting seat phosphorus are indirectly deficient or separated, truly realizing zero wear and zero leakage.
-
ANSI Soft Sealing Ball Valve-Fixed Ball Valve
Medium and low pressure, small diameter fixed ball valve, trunnion type. High pressure, large diameter fixed ball valve adopts support plate.
-
ANSI Soft Sealing Ball Valve-Floating Ball Valve
Elastic valve seat structure design, and the contact area between the adjusting seat and the sphere will change with the medium pressure, so that the sealing pressure can be adjusted as required to ensure reliable sealing and low switch torque.
-
ANSI Gate Valve
The gate valve refers to the valve door where the closing piece (ram) moves along the vertical direction of the centerline of the passage. The gate valve can only be used in the pipeline to fully open up and pay attention to new uses, and should not regulate or reduce expenditure.
