Product Details

NSV Monoflange due to its one-piece design,that can withstand high overpressures. It ensures a robust and compact mounting of the measuring instrument directly to the process flange. The use of metal and graphite seals allows working at high temperatures.

In combination with pressure measuring instruments, diaphragm seals or level measuring instruments, the valves are suitable for use in critical applications like refineries or steam generation systems.

By combining customer-specified valves into a single manifold valve, NSV’s monoflange significantly reduces the number of potential leak paths. The monoflanges also have a lower system mass, which reduces loading and vibration stresses, further improving safety and reliability. The NSV Monoflange has needle valve primary and secondary rather than ball valves. The monoflange is preferred by some operators as it is smaller than a traditonal double block and bleed valve, giving even more space and weight advantages. This ensures that the monoflange is it is a cost efficient option for owner / operators.

The monoflange allows the mounting options to suit whether the pipeline is vertical or horizontal, the gauge or pressure transmitter can be fitted on either the front face or on the outer diameter of the body to allow good orientation and ease of reading.
