Econosto has included a new series of double block & bleed valves from Vimec, a quality Italian brand, with a complete range of integrated DBB valves, in its product range. These valves are used in chemical and petrochemical industries, oil and gas industries, refineries, the energy sector, the maritime industry, for onshore and offshore applications and in water treatment plants. All valves are designed in accordance with international specifications and standards, including ANSI, ASME, API, NACE and BS.
Integral DBB valves are mainly used for instrumentation applications and are available in many design options, including dual-flange or flange-thread connections and for applications such as injection and sampling. The most significant advantage of a full DBB structure is that the use of two valves in a single housing provides a higher degree of safety.
A bleed is located between the two valves in the form of a needle valve. When it is opened the medium present in the main valve is bled, thereby reducing pressure to atmospheric pressure.
