These blocks are used for installation of safety valves type DBDS (see section 9.1) which must be ordered separately. The BPV type is built in sizes 6,10,20 and in the “G” versions with the threaded connections BSP ISO 228 or in the “P” version for mounting on plate.
The safety valves VS 224 are designed and manufactured by Epe Ita-liana. They have soft seal and total l i ft. They have a high flow coefficient (K = 0.95) and are sui table for gas and l iquids.
The two-way ball valve is used to detect the safety valve type VS224 and to remove it for periodic recalibration, without having to fully di-scharge all the nitrogen of accumulator/accumulator station. The ball of the valve is located between two pre- compressed seals provided with a floating system, so it is guaranteed a perfect seal at both low and high pressure.
The three-way ball valve is used to detect the safety valve type VS224 and to remove it for periodic recalibration, without having to fully di-scharge all the nitrogen of accumulator/accumulator station. The ball of the valve is located between two pre- compressed seals provided with a floating system, so it is guaranteed a perfect seal at both low and high pressure.
