International Standards that recognize and mandates the use of DBB Valves

DBB – Norsok and OSHA are international standards for energy isolation.

Industry giants with the likes of Shell, Exxon, BP, Total and any major players for that matter, have rules and standard set in place dedicated to one subject area called Energy Isolation. Energy source could be in various form such as electrical, heat or pressure energy. Different companies and state agencies will have varying regulations and engineering practices for system or equipment isolation during maintenance and intervention. Nevertheless, regardless how minor or how critical the isolation requirement, the objective is to always meet the minimum “safety requirements”.

Smart DBB Valve Technology

DBB - Endusers have cost reduction of 30 percent.

DBB Valves: Traditional installations of DBB Valve systems at plants are very time consuming and an expensive practice. A traditional system consists of two single ball valves, a needle valve, various connectors, adaptors and flanges. There are many steps to consider when completing the installation process. In total, there can be as many as 41 steps required for a traditional installation of DBB valves setup.

Torque is more than meets the eye

DBB - Valve torque requirements for a safe process application.

When considering the torque values to operate the valve, one must consider how much torque is required to fully open and fully close the valve. If the valve gets stuck in mid function of opening or closing the valve a safety factor must also be considered sizing the actuator.

Compact DDB Valves for Modular Plant Systems

DBB - Manufactoring compact valves for oil and gas industry.

Construction of modularized plant system has become a popular choice of design in heavy process industries like the Oil/Gas and Petrochemical Sector. Modularization is where equipment, vessels, piping, valves, instrumentation and electrical/controls are mounted on a compact steel framework, commonly called “skids”.

Important Facts about Fire Safe Standards

DBB – Fire safety solutions and difference between test, design and approvement.

Reliable fire protection is essential for industrial valves in industries with sensitive applications. Because of the dangers that come within installations in the oil and gas, chemical, and petrochemical industries, the valves used must guarantee a reliable and safe shut-off in case of fire.

How the position of levers can influence the usability of DBB Valves

DBB - Position of levers can influence the usability of DBB valves.

Several Ball Valve basic designs are common and therefore a lot of different solutions are available on the market. Especially the position / orientation of the levers have an enormous influence on the usability of the valve, when used in horizontal installations. The following pictures are showing two different options.

Single Ball DBB vs. Dual Ball DBB

DBB - Difference between dual ball DBB and single ball DBB.

Very often our sales people are being asked why to use a DBB Dual Ball Design and not just a Single Ball Design. A Single Ball Design would be much cheaper.

Well, the answer is very simple: Safety and Process Reliability.

Here is a simple infographic to explain the benefit of the Dual Ball Design.
