BLOCK & BLEED VALVES CONTENTS Introduction Application installaltions Specification Ball valve type OS&Y Needle type Glove Needle Valve type Block & Bleed valve Monoflange valve 3 4-6 7-5 6-9 INTRODUCTION NACO's response to the demand for reduction in leakage paths has been the combination of primary and secondary valves into one compact unit. The combining of piping and instrument valves into a single unit has benefitted various markets. NACO can offer the special combination of double block and bleed valve systems together with fittings, both being designed and produced by BMT. Choise of this combination results in the elimination of taper thread connections and the need for thread sealant.
Block & Bleed Valves APPLICATION & INSTALLATION SOLUTIONS NACO instrumentation products provided the ultimate suitable solutions for a integral block & bleed valve, which is consist of one piece forged body it provide many merits, featuring a choice of end connections, body style and Conventional Installation <> # A welded flange, connected to a primary ANSI class isolating valve. The primary valve will be connected to a secondary instrument valve. A pressure gauge or transmitter will then be installed downstream of the instrument valve. NACO BLOCK & BLEED Valve <> # A one-piece integral forging incorporating up 3 ball valve or mixture of ball and needle design. # Improved safety : leak paths reduced by up to 60% # Reduced costs : installation and component costs reduced by up to 70% # Reduced weight : by up to 80% # Reduced susceptibility to problems caused by vibration. NACO Monoflange <3> # More compact then NACO DBB valve, adding further space and weight saving possibilities. # Improved safety : leak paths reduced by up to 60%, less susceptibility to vibration # Reduced costs : installation and component costs saving up to 80% # Reduced weight : up to 85%

Block & Bleed Valves SAMPLING VALVE This manifold range is designed to replace conventional multiple-valve installations where sampling of the process stream is required. This design has been developed to remove a sample directly from the process stream at full system pressure. Sampling probe The probe length must be specified from the raised face to the end of the probe in mm, to the nearest mm. Probes are supplied to suit the insertion length required by the pipeline and thus must be specified by the customer CHEMCAL INJECTION VALVE This manifold range is designed to replace conventional multiple-valve installations where injection into the process stream is required. This design has been developed to inject directly into the process stream at full system pressure. Injection quill The probe length must be specified from the raised face to the end of the probe in mm. Probes length shall be decided in consideration of injection insert length in the pipeline and customer's request. Non return check valve This poppet type spring return valve has a viton soft seal(sepool standard)
Block & Bleed Valves FUGITIVE EMISSION ISO 5848 parts & (defining a classification system and qualification procedures, and production acceptance test of industrial valves, respectively) specify new ultra low standards for emissions. This standard is becoming the requirement for oil and gas and petrochemical organizations worldwide. The standard was originally created for process valves and control valves but is now being applied to Instrument valves which include primary isolation valves, especially on environmentally sensitive projects. Meeting these low levels is a challenge, which BMT Instrument has solved with the new ball and needle valve designs used in these DBB valves and mono flanges. These designs meet the highest class A level over the temperature range -9 C to +80 C, alongside the standard instrumentation manifold pressure ranges. Production testing and certification is available upon request. Please specify sample quantity required for production testing with your order. Valve Specification Tightness class A > x 0-6 mg.s-.m-. Maximum cold working pressure rating 6,000 psig. Temperature rating -9 C to 80 C (-0 F to 356 F) ISO5848- prototype tested using global helium vacuum method. Perfoemance class -ISO FE AH-CO-SSA-t(RT, 80 C)-ANSI500-ISO 5848- The ISO 5848 standard effectively sets a requirement for zero emissions for processes involving volatile air pollutants and hazardous fluids.this design has been developed to minimise fugitive emissions.
