German HORA valves HORA models HORA prices

HORA valves, also known as speed synchronization valves, are a general term for flow divider valves, flow collector valves, one-way flow divider valves, one-way flow collector valves, and proportional flow divider valves within 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 synchronous control hydraulic systems using flow divider-collector valves (synchronization valves) have 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 flow divider-collector valves is speed synchronization. When two cylinders or multiple cylinders bear different loads respectively, the flow divider-collector valve can still ensure their synchronous motion.

HORA valve functions

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

HORA valve classification

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

HORA valve difference between flow collector valves and flow divider valves

1) The flow collector valve is installed on the return oil lines of two actuators, combining the return oil flow from the two loaded paths for return; 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 collector 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 collector valve is exactly opposite to that of the flow divider valve; 3) The flow collector valve can only ensure synchronization during the return oil stroke of the actuators.
