[Piping, Automatic Valves, Valve Technology] Motor for Electric Opening and Closing Actuators
MMC Series
Technical explanation of flow control and automatic valves. There is a track record of using electric actuators for opening and closing control and motors for fluid control lines.
"Valves" are responsible for fluid control such as water, oil, gas, chemicals, and powders in factory equipment, various plants, water treatment, semiconductor, and food manufacturing lines. Depending on the application and fluid characteristics, a variety of structures are used, including butterfly valves, ball valves, globe valves, diaphragm valves, and sanitary valves. The transition from manual valves to "electric automatic valves (electric actuator)" is essential for labor-saving, high-precision flow control, and remote monitoring. When selecting electric valves, important technical elements include the "tightening torque (operating torque)" that moves the valve body, prevention of water hammer caused by rapid closure, "sealability (selection of seat material)" to prevent fluid leakage, and "flow proportional control" through fine opening adjustments. Particularly in high-viscosity liquids or fluids containing solids, measures against overload during valve jamming and high torque retention are challenges. While Kuru Co., Ltd. is not a manufacturer of valves themselves, they have a track record of using their own products as "opening and closing actuators" to drive various valves and as motors for the piping lines before and after.

basic information
■Typical Valve Structures and Selection Points - Butterfly Valve / Ball Valve: Fully open and closed with a 90-degree rotation (quarter turn). The structure is compact, suitable for large diameter piping and high-speed opening and closing. - Diaphragm Valve / Globe Valve: Flow adjustment by moving the diaphragm or valve body up and down. Ideal for chemical and sanitary applications and fine adjustments since the fluid does not contact the drive components. ■Technical Challenges in Electric Valve and Actuator Implementation - Water Hammer Phenomenon Countermeasures: Smooth deceleration and correction actions to prevent shock waves generated in the piping when the valve is suddenly closed. - Opening Degree Control (Proportional Flow Control): Positioning performance that precisely controls the valve opening from 0 to 100% using pulse signals or signal lines. ■Motor Adoption Achievements Around Equipment - High-precision opening and closing control and opening degree retention in the actuator section of electric valves (Stepping Motor MR Series). - Drive for fluid control piping lines, pumps, and metering supply units (Brushless Motors/Gear Motors).
