A lubricated plug valve with pressure balance is a type of industrial valve designedto regulate the flow of fluids within a pipeline. In this context, "lubricated" typically refers to the use of a lubricant or sealant to reduce friction and ensure smooth operation of the valve mechanism. The presence of a pressure balance feature in the valve design is intended to maintain equilibrium or equalized pressure across different areas of the valve, which can help to enhance the overall performance and reliability of the valve, particularly in high-pressure applications.The combination of lubrication and pressure balance in a plug valve is aimed at improving its durability, efficiency, and ability to withstand demanding operating conditions. These features can contribute to reduced wear and tear, enhanced sealing integrity, and smoother operation, ultimately leading to improved performance and longevity of the valve in industrial settings.If you have specific questions about the design, application, or maintenance of lubricated plug valves with pressure balance, feel free to ask for more detailed information.1. Pressure balance type inverted oil seal plug valve product structure is reasonable, reliable sealing, excellent performance, beautiful appearance; 2. Oil seal plug valve inverted pressure balance structure, light switch action; 3. There is an oil groove between the valve body and the sealing surface, which can inject sealing grease into the valve seat at any time through the oil nozzle to increase the sealing performance; 4. Parts material and flange size can be reasonably selected according to actual working conditions or user requirements to meet various engineering needsThe after-sales service of the floating ball valve is very important, because only timely and effective after-sales service can ensure its long-term and stable operation. The following are the after-sales service contents of some floating ball valves: 1.Installation and commissioning: After-sales service personnel will go to the site to install and debug the floating ball valve to ensure its stable and normal operation. 2.Maintenance: Regularly maintain the floating ball valve to ensure that it is in the best working condition and reduce the failure rate. 3.Troubleshooting: If the floating ball valve fails, the after-sales service personnel will carry out on-site troubleshooting in the shortest possible time to ensure its normal operation. 4.Product update and upgrade: In response to new materials and new technologies emerging in the market, after-sales service personnel will promptly recommend update and upgrade solutions to customers to provide them with better valve products. 5. Knowledge training: After-sales service personnel will provide valve knowledge training to users to improve the management and maintenance level of users using floating ball valves. In short, the after-sales service of the floating ball valve should be guaranteed in all directions. Only in this way can it bring users a better experience and purchase safety.
