BB4-Single Block and Bleed Valves

IntroductionHikelok unique combination of double block and bleed valve systems enable a smooth transition from the process piping systemto instrumentation, providing fewer potential leak points, lower installed weight, and a smaller space envelope. Block and Bleed Valves are designed for process piping isolation points,direct mount to instruments,close coupling of instruments,double block and bleed isolation,vents and drains
FeaturesMaximum working pressure up to 10000 psig (689 bar)Working temperature from -10℉ to 1200℉ (-23℃ to 649℃)Flanged connections comply with ASME B16.5Stainless steel, carbon steel, Alloy 20, Alloy 400, Incoloy 825, and duplex stainless steel materialsUtilising bar stock bodyCombines piping & instrument valves in one bodyWeight, space and cost saving over traditional designsStandard high performance bonnet designBlowout-proof valve stems and needlesCombinations of ball valves and needle valves in various configurationsComplete traceability of materialsBleed port equipped with plugOptional port sizes and threads available
AdvantagesWeight, space and cost saving over traditional designsOne-piece structure to realize an efficient transition from the process pipeline to the instrument pipeline while reducing potential leakage points. Different material are available■Independent handle nuts lock stem assembly in place if handle is removed.Live-loaded stem seal ensures positive sealing across the pressure and temperature rangeStem and body shoulders are separated by PEEK thrust bearing to ensure smooth, low-torque actuation.Body seals protect threads from system mediaCavity pressure relief prevents overpressurization from thermal expansion of system media when the valve is closed
More OptionsOptional material 316 stainless steel, carbon steel, Alloy 20, Alloy 400, Incoloy 825, and duplex stainless steel materialsOptional block and bleed: ball valve,needle valveOptional for sour gas service
