Manual Jacket Insulation Top Entry Ball Valves for Petroleum and Natural Gas

Our fixed top entry ball valve also adopts an integral design. The threads are used to adjust the sealing between the valve seat and the ball, allowing online maintenance of the valve. The valve seat has two design structures, DIB-1 and DIB-2. DIB-2 is mostly used for ultra-low temperatures. The center of the lower stem fixing ball makes it easier to open or close the valve, more suitable for large diameters and high pressures. The valve can also be designed with a greased seat and stem.ZJINCONEL Valve Co., Ltd., Zhejiang is located in Yongjia County (known as the Production Base of Pumps and Valves in China), Zhejiang Province.
