German METAL WORK valve, METAL WORK model, METAL WORK price

METAL WORK valve, also known as a speed synchronization valve, is a general term for flow divider valves, flow combiner valves, one-way flow divider valves, one-way flow combiner valves, and proportional flow divider valves among hydraulic valves. Synchronization valves are mainly applied in hydraulic systems with dual-cylinder and multi-cylinder synchronous control. There are many methods to achieve synchronous motion, but the synchronous control hydraulic system using a flow divider-combiner valve (synchronization valve) has many advantages such as simple structure, low cost, ease of manufacturing, and high reliability. Therefore, synchronization valves are widely used in hydraulic systems. The synchronization of a flow divider-combiner valve is speed synchronization. When two or more cylinders bear different loads respectively, the flow divider-combiner valve can still ensure their synchronous motion.

METAL WORK valve function

The function of a flow divider valve is to supply the same flow rate (equal flow division) from the same oil source in a hydraulic system to two or more actuators, or to supply flow to two actuators in a certain ratio (proportional flow division), so that the speeds of the two actuators remain synchronized or in a fixed ratio. [1] The function of a flow combiner valve is to collect equal return flow rates or return flow rates in proportion from two actuators, so as to achieve speed synchronization or a fixed ratio between them. A flow divider-combiner valve combines the functions of both a flow divider valve and a flow combiner valve.

METAL WORK valve classification

According to the adjustment method, they are divided into: fixed flow divider-combiner valves, self-adjusting flow divider-combiner valves, adjustable flow divider-combiner valves, and combined self-adjusting and adjustable flow divider-combiner valves. The above series of hydraulic valves can be designed as small-flow flow divider-combiner valves. Among them, the fixed-structure synchronization valve can be further divided into two structures: reversing piston type and hook head type. According to the flow distribution method, this series of hydraulic valves can also be divided into equal-flow flow divider valves and proportional-flow flow divider valves, and the commonly used ratio is 2:1. Small-flow synchronization valves can also be designed according to the required ratio.

Difference between METAL WORK valve flow combiner valve and flow divider valve

1) The flow combiner valve is installed on the return oil line of two actuators, combining the return oil flow from the two load paths; 2) The two flow sensors of the flow divider valve share the inlet pressure; the greater the flow through the flow sensor, the lower its outlet pressure. The two flow sensors of the flow combiner valve share the outlet; the greater the flow through the flow sensor, the higher its inlet pressure. Therefore, the pressure feedback direction of the flow combiner valve is exactly opposite to that of the flow divider valve; 3) The flow combiner valve can only ensure synchronization when the actuators are returning oil.
