An Introduction to Stainless Steel Ball Valves

Aug 20, 2020
A stainless steel ball valve is widely used in various fields. Its superior quality and high performance stability can not be achieved by ordinary cast steel ball valves, and its service life is far longer than that of the cast steel ball valve. Stainless steel ball valves are widely used in city gas, city heating, petrochemical, shipbuilding, steel, pressure regulating stations, power plants and other pipeline equipment. Stainless steel ball valves can operate reliably for a long time. It needs maintenance and it is easy to install. The installation of stainless steel ball valve is more convenient.

Performance of stainless steel ball valves
1) Maintenance, adjustment and lubrication are not required. It is easy for installation. And it can be opearted in a long-term reliable operation at low operating cost. The surface of stainless steel ball valve is sprayed with plastic technology and has beautiful luster, which has been at the leading level in China. There will be no external leakage. It is very simple to install the adjusting mechanism. The operating handle can be removed and installed in reverse direction.
2) Since the valve seat is composed of carbon fiber reinforced Teflon sealing ring and disc spring, it has very good adaptability to the change of pressure and temperature, and there will be no sliding within the marked pressure and temperature range.
3) The machining process of the sphere is tracked and detected by advanced computer detectors, so the machining accuracy of the sphere is high.
4) As the valve body material is the same as the pipe material, it will not cause uneven stress and deformation due to earthquake and vehicle passing through the ground. Then, the pipeline is aging resistant.
5) It adopts fixed balls and floating balls, double piston effect sealing systems and automatic injection of sealant type bearing.
6) In order to prevent static electricity, steel balls and springs are respectively installed between the valve stem and the ball and the valve stem and the packing box, which can keep the electric conduction between all parts of the valve and the valve body. It can let the current pass through the area to release static electricity. It can not only prevent fire, but also prevent corrosion and achieve temporary cut-off for timely maintenance.
7) The valve stem anti dropping function is because the valve stem is affected by the pressure in the valve. And the total force is generated, so the valve stem is designed as an anti dropping structure.
8) Push the pressure to the valve stem with thrust washer support of low friction material so that the valve stem can only serve to transmit torque.

Application ranges of stainless steel ball valves
1. City gas: gas export pipelines, branch supply pipelines, etc.
2. Central heating: output pipelines, trunk line and branch line of large heating equipment.
3. Heat exchanger: opening and closing of pipes and circuits.
4. Iron and steel plants: all kinds of fluid pipelines, waste gas selective discharge pipelines, gas and heat supply pipelines and fuel supply pipelines.
5. Various industrial equipment: various heat treatment pipelines, various industrial gas and heat pipes.
