Choice, use, maintenance and warranty conditions of all BLB products are described in the 2006 BLB general monoblock valves of the BM40 series are characterized by a single body having following features:- Low production costs- Sound construction- Compact size- Reduced weightMonoblock valves are generally used when no auxiliary valves are needed and the inside circuits are not too , the absence of tie rods and intermediate seals allow monoblock valves to provide.

6 - Improved dependability- Sturdy valves body for fewer leak points- Lower maintenanceAbove characteristics suggest that monoblock valves are ideal for use in mobile machines 10 BACOBAPT 10 BAT2PP2 VLBBTAPT10BA2 TCCPPWITHOUT relief VALVETCLOSED CENTERP2 STANDARDTHIGH PRESSURE CARRY OVER(POWER BEYOND)5BM40 DESIGNATION SAMPLEBM __ / __ __ __ (_)__/C __ __ __/__Mandatory fi eldOptional fi eldTYPE OF VALVEBM403 GU MO B2 MO A1MO K16 NUMBER OF LEVERSTYPE OF THREADSRELIEF VALVE TYPETYPE OF ACTUATOR (manual)SPOOL TYPESPOOL CONTROL TYPE TYPE OF ACTUATOR (manual)SPOOL CONTROL TYPETYPE OF ACTUATOR (manual)SPOOL TYPESPOOL TYPESPOOL CONTROL TYPE6BM40 TECHNICAL CHARACTERISTICS1 APP20B23968639582296722134581,5M8M83535A 35302127952B191023 LIBM40T2 TBAABT220P T - oil temperature 50 C - viscosity 32 mm /s(PSI) bar(218) 15(145) 10(73) 5010(2,6)20(5,2)30(7,9)40(10,5)50(13,2)P TPTl/min(GPM)6543217number of working sections(PSI) bar(290) 20(218) 15(145) 10010(2,6)20(5,2)30(7,9)40(10,5)50(13,2) P A/BPl/min(GPM)(73)
