How Double Block & Bleed made

How Double Block & Bleed made

Theterm double block and bleed primarily meant 2 separate block control deviceswith a bleed and pipe valve between the valves to check for leakage. The blockand bleed valve has 2 free seating slips that are automatically expand againstthe body seat by the downward action of the tapered plug. The seating slip willclose with both low and high force imposed on both downstream and upstreamsides of the control device. With the product now the trapped in the centercavity between the 2 independent slipsand the body bleed control device can be opened to confirm hundred percentpositive shutoff as low or high force, https://www.kp-lok.com/product/double-block-and-bleed-valves/.

Inthe conventional assembly the force tools, both the instrument and pipingdepartments are involved in ordering and stocking separate control devices,gasket and other fittings. Assembling so many parts can be costly, particularlyif joint welding is needed, and procedures up to eight potential leak points, whilealso taking up working area and generating a big bending moment. The highermass can also bring on vibration stress failure, " Wade Brandon says,Sales and marketing, Vice present." Our special approach for top forceapplications delivers an affordable, out-of-the-box solution, with decreasedinstallation costs, lower height and weight, fewer leakage points, that needsno mounting brackets and that is largely unchanged by system vibration, hesays.

DBBvalves are hundred percent tested to make sure fast start-up and best operationout of the box. They meet both tool and piping engineers features and deliverimportant saving on area, cost and weight when matched with old double blockand bleed valves. As an outcome they are well matched for use in importantapplications such as double block and bleed, primary isolation, force tooldevices, sampling force equalization, among others.

Doubleblock and bleed control devices are accessible in a big range of stuffs of constructionto relax specific application needs. Body and end flanges are accessible induplex steel, stainless steel, and super duplex. Seals spec PEEK seats foramazing resistance to heat, chemicals and wear. Further materials areaccessible for top temperature service.

DBBvalves are rated for use with working force from 10,000 or 15,000 psi and speca special trunnion ball shape for highest performance low-torque and smoothoperation. They give full traceability of stuffs, and a blow-out proof stem forraised safety. They are accessible with clamp-hub kind ends to relax API 17D features,and can be made to relax NACE MR-01-75 for decay protection.

Saves time space and cost

DBBsave space, time and cost by decreasing weight in critical places, eliminatingextra piping needs as well as the need for expensive multivalve systems.Addition to removing tool for repair or service while the facility continues inoperation, you can use it any place you want to stop product contamination. TheDBB valve can also be used in multi-product manifolds.
