High-pressure welded ball valves are widely used for high-pressure pipelines in urban construction, chemical industry, metallurgy, petroleum, pharmaceutical, food, beverage, environmental protection and other industries. which can effectively cut off or connect the medium in the pipeline. They can also be used for regulating the fluid. V-shaped ball valves can perform more accurate flow regulation, while the three-way ball valve is used to distribute the medium and change the flow direction of the medium. The media in the welded ball valve are mainly compressed natural gas, water and steam.
High-pressure welded ball valves are the key device for high-pressure pipelines transporting oil and gas. They adopt a unique sealing structure and self-sealing material. The deformation caused by welding is strictly controlled. The toque is stable. An innovative metal plating is adopted. The material and structure are optimized. All of these make the high-pressure welded ball valve have good mechanical properties and corrosion resistance.
Specifications of high-pressure welded ball valves
Nominal pressure: 16 to 32Mpa
Applicable temperature ranges: -20 to 350℃
Scope of applications: for water, oil, gas and various liquids
Welding types: butt welding (BW) and socket welding (SW)
Features of high-pressure welded ball valves
The design of self-sealing
The design of the welded ball valve is related to its applications. Compared with other valves, high-pressure welded ball valves are designed with self-sealing to ensure better use value. The higher the pressure is, the more reliable the sealing becomes.
High testing pressure
High-pressure welded ball valves used in the market adopt high-pressure impact and forging. After the valve shell is treated by strengthening treatment, the test pressure can reach 50Mpa.
For ball valves with LPG or natural gas, their pressure should be considered when designed and installed.
Corrosion resistance and high-temperature resistance
The performance of ball valves should be always considered. Dervos Valve can provide high-pressure welded ball valves with good high-pressure resistance, high-temperature resistance, corrosion resistance and other properties, which can guarantee that the welded ball valve can play a good role when it is used.
To sum up, you can choose high-pressure welded ball valves based on their three features. The valve should be designed based on the relevant rules to ensure good performance. The valve can play a good role when cutting or connecting more media.
