Various other connection types and sizes are available for our DBB valves, from threaded to welded and hubbed. They have a Standard Temperature range up to 120 Deg C to 200 Deg C.  All NPT connection threads are Single Point CNC machined.The innovative design of our Instrumentation Double Block and Bleed Valves enables them to perform in both high and low temperatures pressures and with a wide variety of media. 

A smaller unit vs the traditional hook-up means less weight, which is significant on the top side of a platform when you combine all the pressure instrument take-offs. The typical installation is reduced from 33kg to 7kg, a weight reduction of 75%, a major benefit within the industry. 

Weight reduction is also an issue when take-off is horizontal because a bending moment and could cause a critical fracture of the pipeline-interface. This is often overcome by adding more stanchions to support traditional installation, which adds even more weight.

Cost reduction is typically a 30% saving over traditional installation methods, but this could jump to 70% for valves that are created out of exotic materials. For cost-saving onsite, the testing of one component compared to different flanges, connections, etc., as well as the cost when raising purchase orders and chasing parts or goods received, can be reduced. The shipping costs are often higher and weightier when there are more parts; rises in cost can be 30% of the overall cost.
