VALVES ARE DEVICES USED TO CONTROL THE FLOW OF A FLUID OR GAS BY OPENING OR CLOSING A PASSAGEWAY. THERE ARE VARIOUS TYPES OF VALVES USED IN INSTRUMENTATION, INCLUDING GLOBE VALVES, BALL VALVES, NEEDLE VALVES, AND GATE VALVES. THESE VALVES CAN BE OPERATED MANUALLY, OR THEY CAN BE AUTOMATED USING ACTUATORS, SUCH AS ELECTRIC MOTORS, PNEUMATIC OR HYDRAULIC CYLINDERS, OR SOLENOIDS
MANIFOLDS, ON THE OTHER HAND, ARE A SERIES OF INTERCONNECTED VALVES AND FITTINGS THAT ARE USED TO COMBINE, DISTRIBUTE, OR REDIRECT FLOW IN A PROCESS SYSTEM. THEY ARE DESIGNED TO PROVIDE A COMPACT AND CONVENIENT WAY TO CONNECT MULTIPLE INSTRUMENTS, SUCH AS PRESSURE GAUGES, TRANSMITTERS, AND SWITCHES, TO A SINGLE PROCESS LINE. MANIFOLDS ALSO HELP TO SIMPLIFY MAINTENANCE AND CALIBRATION PROCEDURES BY ALLOWING FOR EASY ISOLATION OF INSTRUMENTS WITHOUT DISRUPTING THE PROCESS FLOW
VALVES AND MANIFOLDS ARE CRITICAL COMPONENTS IN PROCESS CONTROL SYSTEMS, AND PROPER SELECTION, INSTALLATION, AND MAINTENANCE OF THESE COMPONENTS ARE ESSENTIAL TO ENSURE SAFE AND EFFICIENT OPERATION OF THE SYSTEM
VALVES AND MANIFOLDS ARE IMPORTANT COMPONENTS USED TO CONTROL AND REGULATE THE FLOW OF FLUIDS OR GASES IN A PROCESS SYSTEM.
