Cast Steel Flanged Concentric Butterfly Valve

I. DESIGN FEATURES OF TRUNNION FLANGE BALL VALVES The design of TRUNNION FLANGE BALL VALVES is an important guarantee for their performance and reliability.According to the information I've searched, TRUNNION BALL VALVES​ usually adopt a three-piece or two-piece structure. Their characteristic is that the ball is fixed on the valve seat and will not shift when the valve is closed, thus ensuring stable and reliable sealing performance. In addition, they have a low operating torque and uniform sealing, making them suitable for high-pressure and large-diameter working conditions. For example, the Q476F type three-piece soft-seal flange ball valve of the J-VALVES brand is designed in accordance with API standards and has excellent sealing and pressure resistance.

I. IntroductionThe J-VALVES 15Mo3 gate valve is a high-performance fluid control device, which is widely used in industrial pipeline systems. This article will, from the perspective of comparative analysis, analyze its performance characteristics in detail and provide a comprehensive operating guide

1.PERFORMANCE COMPARISON: SOFT-SEAL PLUG VALVES: · SOFT-SEAL PLUG VALVES mainly rely on soft sealing materials to achieve sealing. They possess good sealing performance and low opening torque, and are suitable for pipeline systems carrying water, gas and non-corrosive media. · Their design features include low-torque operation, anti-static function and fireproof design, making them particularly suitable for occasions that require frequent opening and closing or high sealing requirements. · Under ultra-low or high temperature conditions, their torque requirements will increase, but they can still maintain stable performance through optimized design.
