NAILOK Stainless Steel Alloy 625 Double Valve Process Monoflange Valve
Double Block and DBB Ball Valve has Dual ball structure which evolved to replace and add the process of bolting together individual valves to make the valves in one body. it saved a lot of space and material, it is the development tendency of the valve in the future.

Mono Flange Valves are used as an alternative to a system which has multiple valves. They are designed specially to provide a compact installation for transmitter and gauge instruments. In an application where a monoflange is used, it is used toreplace other equipment. For instance, rather than having one valve and relying on it to close so that you can isolate the transmitter, two different valves can be used. In such case, a 316/316L Mono Flange Valve would replace two different valves perfectly. With this, you won't need to have two different valves but a single one. This is because the monoflange is composed of two different closed valves as well as a vent which is opened so as to limit the pressure which is between them. It also has a reduced weight as well as minimal leak paths thereby providing a higher integrity system. The reduced length of the installation likewise reduces the risk of damage through vibration. You can either place the 316/316L Mono Flange Valve horizontally or vertically so as to ensure the gauge is standing upright. This is perfect for primary isolation i.e. double block and bleed, as well as instrument duties. A monoflange also make provision for isolation, instrument mounting and venting in a single unit.
