Monoflange Valve
Monoflange Valve
Introduction
Monoflange Valve are a unique valve design that combines the functionality of a valve and a flanged connection in a single compact unit. These valves are typically used in applications where space and weight reduction are critical, as they eliminate the need for a separate flanged valve and associated flanges. The Monoflange design offers a simplified installation process, reducing installation time and cost while providing a reliable and leak-proof connection.
The design of the YDB Monoflange Valve is such that it reduces the number of potential leak paths to make your system more safe and compact. Monoflange valves will allow you to achieve significant weight reduction in the system and cost savings. Most operators prefer monoflange over traditional double block and bleed valves as it gives them weight and space advantages.
YDB Monoflange Valve are available in single block, block and bleed, block bleed block, and block block bleed. All YDB monoflange valves are factory tested.

Technical Specifications
Process Monoflange
Process monoflanges replace the traditional isolation valve and are closely coupled to the process piping flange to connect process with instruments. Many markets have benefited from process monoflanges as they combine instrument and piping valves in a single unit. The standard connections for process monoflange are provided in accordance with the ASME B16.5.
Instrument Monoflange
Coupling of instrument monoflanges to a pre-installed isolation valve provides a compact instrument double block and bleed valve. The standard connections for instrument monoflange are provided in accordance with the ASME B16.5.
Applications
Monoflange valves are used in upstream onshore/offshore oil and gas production. They’re also used with gauge pressure instruments to minimize the weight and size of the pipe and valve assemblies used for vent, calibration and primary or/and secondary isolation.
The highly sophisticated design features of monoflange valves make them suitable for several other applications as well.
