Description
KTSM Serial Pneumatic Micro-flow Control Valves are used for precise control of a small flow fluid. The compact valve body is of a forged structure and it is less affected by stress from the pipe. The valve employs a top entry type and parts can be replaced without dismantling the valve from the pipe. The thread-connected valves can be readily disassembled and reassembled without requiring any special tools. They are widely applied for power , chemical, pharmacy , food industry, etc .
