Parker's ProBloc series is designed to replace conventional multiple-valve installations currently in use for interface with pressure measuring systems in process control applications Parker's ProBloc sériés modular valves are designed to replace conventional multiple-valve installations currently in use for interfacing with pressure measuring Systems. The traditional way of creating a double block and bleed valve was to use three separate single isolate bail valves, a tee piece to join them together and a flanged weldolet to connect to the process pipeline. This was modified to boit three valves together using through bolts and was referred to as a modular valve. No supporting is needed as the modular valve is small and light compared to the original method, It is easier to operate as the three valves are much doser together. By building three valves into one body to create double block and bleed valve you reduce the amount of potential leak paths, reduce the weight which is critical in offshore facilities, reduce the size and therefore the space taken up, very important offshore but also in onshore applications. By combining customer-specified bail and needle valves into a single manifold, Parker's ProBloc modular valves significantly reduce the number of potential leak paths. They also hâve a lower System mass. This reduces loading and vibration stresses, further improving safety and reliability. Parker's ProBloc valves are available in a range of configurations, including double-block, block-and-bleed, and block-bleed-block. Standard flange sizes include 1/2", 3/4", 1", 1-1/2", 2” and 3".
