*Ideal reference for industry
*Practical approach compared with competition
*Buyers' guide included
Industries that use pumps, seals and pipes will also use valves and actuators in their systems. This key reference provides anyone who designs, uses, specifies or maintains valves and valve systems with all of the critical design, specification, performance and operational information they need for the job in hand. Brian Nesbitt is a well-known consultant with a considerable publishing record. A lifetime of experience backs up the huge amount of practical detail in this volume.* Valves and actuators are widely used across industry and this dedicated reference provides all the information plant designers, specifiers or those involved with maintenance require* Practical approach backed up with technical detail and engineering know-how makes this the ideal single volume reference* Compares and contracts valve and actuator types to ensure the right equipment is chosen for the right application and properly maintained
