China API/API6d Carbon/Stainless Steel Ss Float/Trunnion/Dbb RF Fnpt Thread/ L Type/ T Type 4 Way/3 Way Manual/Electric/Pneumatic Industrial Gas/Oil/Water Ball Valve, Find details about China Ball Valve, Valve from API/API6d Carbon/Stainless Steel Ss Float/Trunnion/Dbb RF Fnpt Thread/ L Type/ T Type 4 Way/3 Way Manual/Electric/Pneumatic Industrial Gas/Oil/Water Ball Valve
The BALL VALVE is a patented product by China GONGNAI Valve Co. Ltd, the core technology concentrate on TOP-ENTRY TRUNNION BALL VALVE performance where it unique ball sealing and base sealing performance during the opening and closing process. In its operation, the ball is completely suspended in the body cavity during the movement, complete none friction in the ball operation with the valve base sealing contact, attaining zero rubbing effect. The structure of the core valve and the sealing rigid ball are unique and compensate each other, the gap designed on the top of the ball (along the direction of medium flow) enable it to accommodate changes of sphere size.
