Product description

Double throttle check valve is a fluid control device mainly used to regulate and limit the flow of fluid in the system. This valve has a unique structure with a design of two one-way valves combined together, allowing fluid to only pass in one direction and limiting flow rate through an adjustable throttling device. The main purpose of this valve is to achieve precise control of fluid flow, ensuring that the system can maintain stable flow under specific operating conditions. Double throttle check valves are widely used in hydraulic systems, lubrication systems, and other engineering fields to ensure the safety and efficiency of system operation, while providing flexibility to adapt to different working conditions and requirements. By adjusting the throttling device, the operator can accurately control the fluid flow rate, thereby meeting the system's requirements for fluid flow under different working conditions.
