Rexroth Hydraulic Relief Valve ZDR6DA2-43 150Y Fixed Flow Valve For Balancing System Flow

Product Description

Flow control valve, also known as 400X flow control valve, is a multi-function valve that uses high-precision pilot method to control flow. Instead of the conventional throttle valve using orifice plate or pure mechanical principle to reduce the basin area, the use of relevant pilot valves to minimize the loss of energy in the throttling process. High control sensitivity, safe and reliable, easy debugging, long service life.

The flow control valve automatically balances the flow of the system without an external power supply. The flow limit is achieved by maintaining a certain pressure difference between the front and back of the orifice plate (fixed aperture), so it can also be called a fixed flow valve. The constant flow valve acts on the flow rate and can lock the amount of water flowing through the valve, rather than the balance of resistance. He can solve the dynamic imbalance problem of the system: in order to maintain the efficient operation of a single refrigerator, boiler, cooling tower, heat exchanger and other equipment, it is necessary to control the flow rate of these equipment to be fixed in the rating; From the end of the system, in order to avoid the interaction of dynamic regulation, it is also necessary to restrict the flow at the end device or branch. In the design should pay attention to the problem, the disadvantage of the flow control valve is that the valve has the minimum working difference requirements, the general product requires the minimum working pressure difference of 20KPa, if installed on the most unfavorable circuit, it is bound to require the circulating pump to increase the working head of 2 meters of water column, so it should be installed near the end, the far end is not comfortable. When the distance between the user and the heat source is greater than 80% of the heating radius, do not install this flow control valve.
