Ball
Ball Valves

Ball valve, the opening and closing part (ball) is driven by the valve stem and rotates around the axis of the ball valve. It can also be used for fluid adjustment and control. The hard-sealed V-shaped ball valve has a strong shear force between the V-shaped core and the metal seat of the hard alloy surfacing. It is especially suitable for fibers and tiny solid particles. And other media.

Gas

Gas Exhaust Fully Welded Ball Valve

Gas exhaust fully welded ball valve is integral welded ball valve. There is no external leakage. Because the seat is made of carbon fiber reinforced Teflon seal and butterfly spring, it has strong adaptability to pressure and temperature changes. And it will not cause leaks within the pressure and temperature range. The processing of the ball is tracked and detected by an advanced computer detector. So the processing of ball is accurate and high. The gas exhaust fully welded ball valve is widely used in drainage pipe, exhaust pipe, natural gas pipe, etc

Top Entry Floating Ball Valve

Compression spring is applied on the ball, the role of the compression spring is to apply pre-tightening force on the ball, so that the sealing surface of the valve seat is in close contact under any circumstances, and the sealing performance is good. The wedge Angle of the contact surface between the valve seat and the valve body is 10°,the seat is self-locking,In the direction of the line, when the valve seat is subjected to greater pressure, the valve seat will not produce any displacement. Therefore, the valve of this structure has both the characteristics of a gate valve and the advantages of a ball valve. During maintenance and inspection, it is found that the valve body and valve seat are prone to leakage. If the pre-tightening force of the spring is increased, the closing torque of the ball valve is bound to increase. In order not to increase the closing torque of the ball valve, a rubber O-ring is added to the back of the sealing surface of the valve seat to solve the problem of leakage on the back of the sealing surface of the valve seat.

Top Entry Trunnion Mounted Ball Valve

Top entry trunnion mounted ball valves are widely used in petroleum and natural gas pipelines, as well as in oil extraction, oil refining, petrochemical, chemical, chemical fiber, metallurgy, electric power, nuclear power, food, and paper making equipment. The top entry trunnion mounted ball valve is easy and quick to disassemble on the pipeline, and the maintenance is convenient and fast. When the valve fails on the pipeline and needs to be repaired, it is not necessary to remove the valve from the pipeline. It is only necessary to remove the middle flange bolts and nuts, remove the bonnet and stem assembly from the valve body together, and then remove the ball and valve Block assembly. You can repair the ball and valve seat online. This maintenance saves time and minimizes losses in production.

LNG

LNG Top Entry Ultra-low Temperature Ball Valve

The LNG top entry ultra-low temperature ball valve is a very common on-off valve in the transportation of LNG and some cryogenic media. It is an important part of the petrochemical industry, air separation, and energy transportation industry. The top entry ultra-low temperature ball valve adopts a top-mounted fixed valve body with an extension stem in the middle. The internal part can be divided into metal seal and soft seal, and is subjected to repeated cryogenic treatment to ensure low-temperature resistance. The LNG top enrty ultra-low temperature ball valve is suitable for low temperature (-196℃~-100℃) liquid or gas, such as liquefied LNG, LPG, CNG, liquid hydrogen, liquid oxygen, ethylene, etc.

Forged

Forged Floating Ball Valve

Principle of the forged steel floating ball valve: This kind of ball valve has a floating ball supported by two valve seats. Under the medium pressure effect, a certain displacement can be generated by the ball itself so as to be pressed onto the seat seal ring at the outlet, guaranteeing tightness at the outlet.

Forged

Forged Trunnion Mounted Ball Valve

Trunnion ball valves have the obturator bounded by trunnion which prevents axial displacements of the ball itself in the flow direction; line pressure compresses the seat onto the ball, the contact between surfaces generates the valve sealing; trunnion standard construction ensure automatic cavity relief in case of overpressure in body cavity; these valves can be selected for a wide range of applications with no specific limits to all sizes and pressures.
