Stacked throttle valve is a key equipment used to control the flow rate in fluid systems. Its main purpose is to adjust and limit the flow of fluid through pipelines or pipelines to meet the specific working requirements of the system. By adjusting the opening of the valve, the stacked throttle valve can accurately control the flow rate of the fluid, thereby achieving the adjustment of system pressure and flow rate. This type of valve is commonly used in systems that require constant flow or flow adjustment under different operating conditions, such as hydraulic systems, water supply systems, heating systems, etc. The flexibility and precise flow control of the stacked throttle valve make it a common key component in engineering and industrial fields, ensuring that the system can operate stably and efficiently under various operating conditions.
