Flow distributing and collecting valve Diverting and collecting valve, also known as synchronous valve, is an independent hydraulic device that integrates the functions of hydraulic diverting valve and collecting valve. It is the general name of diverter valve, diverter valve, one-way diverter valve, one-way diverter valve and proportional diverter valve in hydraulic valves. Synchronous valve is mainly used in double-cylinder and multi-cylinder synchronous control hydraulic systems. There are usually many ways to realize synchronous movement, but among them, the synchronous control hydraulic system using diverter-collection valve-synchronous valve has many advantages such as simple structure, low cost, easy manufacture, and strong reliability. Therefore, synchronous valves have been widely used in hydraulic systems Wide range of applications.
