Double ball valve includes the following parts: threaded retainers, integral bleed part and single piece body. Threaded retainers have valve fully pressure containing with or without installed end connections. Integral bleed port allowing veri?cation of valve sealing with line pressurized. Single piece body houses two valves, creates two physical barriers between pressure and downstream work.   The double ball valve has advantages in the following aspects: safety, compliance, and robust performance. Firstly, true double block and bleed safety is guaranteed. Since two valves in one solid body allow two physical barriers to pressure when working downstream of the closed valve. And retainers are threaded to the body using Stub Acme threads for durability and strength. This feature makes the valve fully pressure containing with either end connection removed. What’s more, retainers are Xylan coated for corrosion protection and ease of maintenance. And enter bleed port between the valves allows testing of either valve’s performance prior to conducting maintenance work downstream of the valve. Secondly, double block and bleed valves are designed in accordance with API 6A, fully compliant with the latest revision of NACE MR0175-2003 which severely limited the use of 17-4 PH stainless steels for valve stems and   eliminated its use for pressure containing components such as bodies and bonnets. This kind of valves have been ?re tested and certi?ed to API 6FA, API 607 and BS 6755 Part 2. Lastly, double ball valve performance in robust for its stronger weld neck end connections that allow bending loads up to 50% of pipe yield at full working and valve bore sizes chosen to closely, which match the most popular pipe bores to reduce or eliminate ?ow turbulence in the valve bore. In the current time, an improved double ball valve powered emergency release coupling includes two fluid-carrying conduits, each having a ball or plug valve received therein, which are prevented from
