A few days ago, the scientific research project undertaken by the National pipe network Group construction project management company was "large-caliber forced sealing.

The NPS24 Class 900 forced sealing ball valve, developed in the "ball valve and axial flow control valve localization" project, completed the field test and expert identification in Changji test site, and successfully passed the industrial test acceptance. Expert experts believe that
The large diameter forced sealing ball valve developed in this subject has independent intellectual property rights, fills the domestic gap, the main technical indicators have reached the international advanced level of similar products, and can be popularized in the natural gas measurement and verification process system.

The forced sealing ball valve is used for measuring pipelines related to measurement and verification to ensure that the measuring pipeline can be reliably turned off when closed, so that the measuring pipeline can meet the requirements of zero leakage to ensure that the measurement and verification results are accurate and reliable. The ball valve is used very frequently in the metrological verification operation process, the main product quality is reliable, the performance is stable, and has the characteristics of accurate adjustment, rapid response, wide adjustable range, stable flow state and so on. Previously, the maximum specification of the localized forced seal ball valve was NPS16 Class900, and the large-caliber forced seal ball valve still relied on imports. If foreign manufacturers cannot provide post-maintenance spare parts in time, it will directly affect the normal use of the valve, and then affect the normal operation of the measuring station. The purpose of the scientific research project of the localization of large-caliber forced sealing ball valve is to solve the problem of relying on imports of large-caliber valves required by the metrological verification branch station of the national pipe network Group, and ensure the maintenance and normal use of the valve in the later stage.
