The Water Meter Speed Reducer is a core precision transmission component for fluid control systems, widely used in smart water meters, flow measurement and control systems, water purification equipment, drinking fountains, water treatment devices, intelligent plumbing systems, and small valve control systems. It enables stable speed regulation, precise angle control, and accurate flow adjustment for these systems, laying a foundation for reliable fluid management.
Specifically optimized for medium-to-large caliber valve scenarios, this Water Meter Speed Reducer is mainly applied to DN40 and DN50 valves. It stands out with high torque output and long service life, effectively solving the transmission challenges of large-caliber valves that require strong driving force and long-term stable operation. As a key support for large-flow fluid control, the Water Meter Speed Reducer ensures that the entire system achieves accurate and efficient control of water flow and valve status.
All parameters are tested under standard ambient temperature (23 °C) and rated voltage, ensuring consistency with actual application scenarios.
