Specification of this Professional Fully Welded Ball Valve Dn80 Factory Price
Fully Welded Ball Valves With the rapid development of science and technology, production technology and continuous improvement of product structure, quickly developed into one of the main valve.The ball valve is widely used in long-distance pipeline, oil refining, power, paper, chemical, pharmaceutical, steel, municipal, water and other industries,the oil pipeline in the area plays an important role. Some ball valves are equipped with an actuator that may be pneumatically or moto operated. These valves can be used either for on/off or flow control. A pneumatic flow control valve is also equipped with a positioner which transforms the control signal into actuator position and valve opening accordingly. As a leading Ball Valve Manufacturer in china, we supplies: floating ball valve,trunnion ball valve,metal seated ball valve,threaded end ball valve,butt welded ball valve,Forged steel ball valve etc, We can manufacture and supply ball valve according to your requirements. 
Parameters of this Professional Fully Welded Ball Valve Dn80 Factory Price

1. Integral Valve Structure

It is welded by forged steel. The forging materials are subjected to ultrasonic examination according to ASME nondestructive flaw detection requirements. The welding slope on the connection face is subjected to liquid penetration examination.

2. Corrosion Resistance And Sulfide Stress Resistance

Certain corrosion allowance is left for the body wall thickness. The carbon steel stem, fixed shaft, ball, seat and seat ring are subjected to chemical nickel plating according to ASTM B733 and B656. In addition, various corrosion resistance materials are available for users to select.
According to customer requirements, the valve materials can be selected according to NACE MR 0175/ISO 15156 or NACE MR 0103, and strict quality control and quality inspection should be carried out during the manufacturing so as to fully meet the requirements in the standards and meet the service conditions in sulfurization environment.

3. Welding Of Transition Pipe

During the manufacturing of the fully welded pipeline ball valve, the transition pipe can e welded for the welding ends valve. The transition pipe can be supplied by users or by our company according to user requirements. Please indicate the transition pipe diameter and length A when placing orders.

Product advantage of this Professional Fully Welded Ball Valve Dn80 Factory Price
The advantages of fully welded ball valves are as follows:
1. The ball valve is integrally welded, so there will be no external leakage.
2. Since the valve seat is made of carbonized Teflon seal ring and spring, the valve is very adaptable to the changes in pressure and temperature and there’ll be no slip with the specified range of pressure and temperature.
3. Processing of the sphere is tracked and detected by advanced computer detector, so the machining precision of the sphere is very high.
4. As the valve material is the same as the pipe material, there’ll be no uneven stress, no deformation caused by earthquake or vehicles running over the ground. And the pipe is aging-resistant.
